I just want to take a minute to tell you my experience with Stewart company. I bought one of their high volume pumps last April and compared to the stock one, the car runs about 20 degrees cooler while cruising for 1 to 2 hours at idle speed.

I noticed a little coolant under the truck in a rest area on a 800 mile trip last weekend but felt around and didn't feel anything so I figured it was left there by somebody else. I kept an eye on the temp gauge and checked for leaks when I got home...none. The next night I went out in the garage and there was about a tablespoon of coolant on the floor. I haven't checked it out real close yet but from what I can reach up behind the pulley, it feels like its leaking thru the weep hole or from the backing plate gasket.

I called them today to get a feel for what my options were and the guy was real courteous and said there would be no problem returning the pump if I find that its bad...they pay the freight..and he is even sending me new mounting and backing plate gaskets to use if I need them....his suggestion. I've only bought one other pump from them and it was still working great when I sold the car with lots of hard miles on it. I'll be taking it apart tonight to see what I find and if there is a problem with the pump I'm confident that they will take care of it quickly. I was real impressed with the way the guy treated me today and I'm pretty fussy when it comes to customer service. I would definitely recommend them. If the pump is bad it doesn't reflect on their quality in my eyes....their reputation is too good for this to be normal.

George, Like i posted alittle bit ago on 40's post. Those are the stories i like to hear about compaines that stand behind there product. Let us know what you find out.

Well, I've got a little to add about my current experience with Stewart Components. First of all when I sent the pump back to them for repair on 7/11, somehow they forgot they told me shipping would be paid by them. They wouldn't cover it so I paid for it. I explained to Mark their customer service guy, that I was pre registered for a show this weekend and would appreciate a prompt turn around if possible. He said he would fix it the day he received it and ship it out the same day. Well, here it is 10 days later and no pump. I called (long distance), was put on hold, then was told they would call me back. They did and said that I should get the pump by Monday or Tuesday of next week. I guess I can drive my Taurus to the show :-( I'm on my way to autozone to get a cheap pump just to get thru the weekend. If it lasts 6 months it will have lasted longer than the Stewart pump did! I spent $90 for this pump to avoid all these problems...I'm not sure I'll do it again. It has already cost me way over $120 plus a lot of grief.

If I sound pissed....I am. I deal with customers everyday and when I tell them I will do something I do it and if I can't I call them and tell them because I know they are depending on what I said.

Nuf said.

George........... you have hit the nail purty hard there.

At the performance tranny / converter place I work for we had a company meeting thursday. The GM tells us at every meeting that he does not have a money printing machine in his office.

He always tells us "we MUST take care of the customers". Returning phone calls is big on his list.

Sure we have problems, but we work to minumize them.

About water pumps......... I just bought a sbchevy pump from Speedy Bill's place Speedway Motors. An aluminum unit for $45.00 plus shipping. I had to modify it. It had a 1.5 inch hose inlet and I needed a 1.75 hose fitting there.

I machined a piece to slip over the smaller fitting & tig welded it on. I imagine my warranty is gone. ((-;

For those of you that know me and all of my posts over the years, wherever they are, I have been a real advocate of the Stewart products and services for years. Howard Stewart is a business friend and now he has sold that company last winter and still is envolved with the function of the company. 99 times out of 100, everytime you talk to one of the many Stewart components employees they are curtious and helpful. They make the best product for it's use in my opinion and I have tested the top of the line.

The mear fact that today's high performance engines require much more and the new and rebuilt stock pumps of yesterdays technology is antiquated and obsolete. The design difference is wide and the performance is just plane tops.

I know some of you out there are reluctant to mess with these new fangled pumps, but in high heat and slow idle speeds on the street it's just what the doctor ordered. There is no downsides to using high flow water pumps, other than they cost a tad more.

I have either put on or recommended hundreds of these pumps for street use and without a complaint or failure.

I hate to have to bring this old thread back but I will until I get Stewart Components to "get it right". As I indicated in posts above, my Stewart pump leaked and I had to send it back to them to be fixed. When I finally got it back I couldn't see where they had broken any seals or turned any of the bolts (it was painted). But I still had faith that they had at least fixed it...even tho it took much longer than their customer service said it would.

Well, I figured it was about time to clean up the truck from Louisville and guess what I found under the truck. As near as I can figure its coming from the very same spot it leaked from before I sent it to them for repairs. This isn't a pleasant job to change water pumps every two weeks....TWICE each time too since I have an autozone pump I'm using while the FAMOUS STEWART pump is being fixed. I don't even want to think about how much I've got into this damn thing now. Its a good thing I don't charge myself labor.

Its 93 degrees out and humid and I just came in from the garage and I had to vent!!!

Oh, by the way, this is what I found.

Hey George.......sorry to hear about the mess.

Ya know something.......I am always apprehensive about companies that buy good companies. The reason is clear and logical. Usually the good one, or the one that gets bought is doing something right and the company that bought them (esp a competitor) is doing something wrong or can't figure out how to do it all. Maybe this is the case with Stewarts?

This WAS one of the deciding factors behind MY decision to go away from Stewarts for a default pump with our pulleys and bracket kits. You just never know what the new guys are going to do. My point here is that I have heard just enough bad stuff of late to put my eyebrows in the air on this takeover.

I have been doing business with TuffStuff....the up and coming newbee!

This is very upsetting. We'll see what they do this time. Rest assured I'll post it here....good or bad.

If these messages are going to do some good, sent the entire page to them!
After all we do have 600 or more members, and countless viewers that are not members. Don't forget we do have a pretty big soap box here.

I'm going to take it off first and make sure its leaking out the weep hole and give them a call. If things go smooth, I probably won't cause trouble. If they don't, the internet is an ace I can play. I'll just see how it goes.

Prolly won't buy another one tho.

Just wanted to share my stewart experience as well. I had one of their "famous" pumps on a 39 ford... and guess what, I had a leak from the weep hole as well. after a fight with the "tech guy" I disassembled the pump myself to find a hole in the casting causing the leak!! I run only edelbrock pumps now, and have had no problems since!!

Well........isn't this interesting and coincidental......I go over to the garage where my 57 sits waiting and hasn't run for over 6 weeks and what do I find.......a leaking Edelbrock pump thru the weep hole? Not much.....but enough! I can't believe that I was going to put this up this morning and find it posted right behind someone else having problems with Stewart(by the way...I have had one Stewart leak on me....then it suddenly went away......??). Regardless of spot problems......I think the two manufacturers are real quality pieces!

Goes to show you.....what I don't know. I'll replace it this winter when the 385/385 goes in!

Wouldn't some seepage be normal if the the motor wasn't started regularly?
Aren't the seals ceramic or carbon? Like an a/c it needs to be lubed by turning regularly?
If the belt was to tight couldn't this cause the pump to leak or leak prematurely? Check side play on the shaft?
A hole in the casting would not be the norm.
If I replaced the same part several times I need to make the cause is not me.
I rebuilt alot of pumps on diesel engines years ago. Maybe these are different.

Well being a new guy here i probably should just be quiet and watch this one.But it is one of the biggest problems(next to poorly built front suspensions)that i deal with with customer rods. I also have some NASCAR exp. soooooo......here goes.We have also used the stewart pump on the race car,great pump but saw NO gains in HP, engine temp, or anything we stopped using them.Now for rods ,if you are looking for the easy way out (buying a trick water pump) it aint gonna work for yah.First things first you must restrict the flow of water with a t-stat or restirctor washer.Reason?cause you do have to try and keep some pressure in the block and stop air bubbles from forming around the ex seats (thats were a lot of heat comes from)We had to slow the pump down for racin(4500-7500rpms all nite) not for power but ot stop cavitation(bubbles)On a rod the biggest thing is tuning the motor first,you dont know how many rods i have see with a nice shinny new alum radiator,3 electric fans a dark blue chrome header and the guy b*tchin about how the radiator or water pump manuf stiffed him.One look and i can tell the guy sets his timing by ear or never has really checked to see if the dampner is indexed to the timing mark correctly(75% of the motors out there with bolt on tabs are off 4-10 degrees)plus never did a plug check in his life,but xyz's car is like that and he has no problems is what i get when i ask.
The cooling system is a whole package and you cant cheap out.Its way to long to post here but radiator size ,fan placement,fan shrouds, grill area,air condenser mounting,Firewall placement (yep the angle on the bottom)Hood sides,pulley sizes,engine compression(on a rod any more than 9.5 to 1 is worthless cause you cant buy the gas anyway)lots of diff thinks effect cooling.Now on to the good part,i am sure some old timer's know this trick.If your having trouble with a water pump neat little test will cost yah about 5 bucks.The chevy is easy,make 2 block off plates for the block side of the pump and bolt them on now. plug the heater hose openning with plugs or caps.Take a short old raidator hose and find a freeze plug that will fit tight in the opening,drill a hole in the freeze plug and install a tire valve stem(you get the idea now )Now put that on the pump were the lower hose goes.Get a bucket of water,CAUTION only put a little bit of air in the pump(maybe 5-8lbs) or you will have a missle freeze plug.(Little hand pump works great)stick it in the water and presto you can see for yourself if its a casting flaw or packing or? Be aware ALL pumps leak a small amount .The one in the pix is not normall LOL That is a lot of coolant for a weep hole.Also do yourself a favor DONT use straight water its no good for the motor,pump or gaskets.At least a 50-50 mix.Try to get the cap pressure up past 16lbs(if you have a good radiator,not some orig recore stuff),everything i build now is over 18 lbs some as high as 22lbs. Hope this helps a little but it doesnt even scrape the surface.Sorry for the long know it all post. Ok hammer away .LOL :)

If you have to trailer it, leave it home!

37NASH.......welcome to the fray. Wow....alot to swallow in one gulp to say the least.

Great comments on tuning your car to keep the cooling issues from biting you, esp the timing and mixture!

But...I have to respectfully disagree with a couple of your points here. First, I have tested water pumps over the last couple of years (many of them) or so and the Stewart pumps DO provide more pressure and volume.....esp compared to stock pumps. Whether or not they take less hp is another conversation. But, the additional pressure greatly reduces the likelyhood of hot spots as you mentioned in your comments. My experience with Howard Stewart is that he is a fine engineer and his products have always produces results. You did not mention what pumps you went to and I would be interested in that. And correct me if I am wrong....but in all racing applications that I have ever seen...including Winston Cup and alot others, the reduction of pump speeds are common with underdrive pulleys. Something a street car should never see I might add. The added pressure and volume that these pumps provide esp at idle and slow speeds are paramount to a successful cooling system these days.

The other point is your commment about the 50/50 mix of water to antifreeze. The specific heat number of water is 1.0. The specific heat number of ethylene glycol (antifreeze) is 0.5. What this means is that it takes two gallons of antifreeze to carry as many BTUs as one gallon of water. In other words.....there is no better heat carrier than pure water......the more antifreeze the worse your engine will carry and displace heat, not my opinion...just chemistry 101 and I know it works. Now I don't recommend pure water to run for the very same reasons that you are thinking but according to all the manufacturers that I have talked to and read thru...they will readily admit that 15% mix of antifreeze to water is enough for corrosion and lubrication. I usually run 20% max here in Atlanta. A higher percentage will only give you better freezing protection. The fine tuning of the coolant works well in very hot locations and problem heat situations, but you have to have the heat removal system in place to be successful with this formula.

I hate to pick on you at such an early time in your arrival here, no offence meant...and you did say let the pounding start or something like that....so we look forward to you long stay I am sure. I have done years of research on cooling systems and what makes them tick specifically. I currently have designed a product for the use on street applications for pulleys and brackets that are also used in the circle track areana as well. I have worked with Howard Stewart and a number of other manufacturers and R&D engineers in this area. As an engineer, I found so much questionable information out there that I had to go after it.....I consider it a safety issue. My kids and wife drives these things as well as many others out there too. You will find one of my cooling ariticles here on the "Articles" site. Please read and give me your critique......I am an information glutten!

Again welcome to the site. What Nascar experience do you have? We have a couple of X-Winston Cup guys here and then there's Johnny Walker.....Humpy's best friend. Can I say more?
