ratrapp Posted May 12, 2011 Share Posted May 12, 2011 last year i ordered a few things from hesco.i got a hgh flow waterpump,high flow t-stat housing and t-stat and the pricey hesco tps adapter to use ho throttle body with a renix sensor.the t-stat housing kept leaking so i had to have the machine shop resurface the housing so it was true and no more leaks,no big deal.the t-stat stuck shut and failed within a year,i replaced it with a mopar piece,once again no biggie.the high flow waterpump has seeped ever since i put it out of the weephole until the seep turned into a leak so i replaced it with a new gmb pump,starting to get a little upset now considering the price of the pump.the final straw has been the tps adapter.i've had a few idle problems ever since i installed the adapter.i blamed it on not being able to get the proper tps voltage because i figured that my tps was going bad.i purchased 2 at the pnp and neither one would go down far enough.my voltage would not go below 1.15 volts at idle.i bit the bullet and purchased a new mopar tps for $120(Ouch) and it also wouldn't go below 1.15 volts so i had to take dremel and slot my brand new factory tps sensor to get the tps down to .90 volts.idle problem gone and tranny shifts good again.maybe i got a bad bunch of parts and the rest of the stuff is great but i'm very dissapointed.what pissed me the most is the waterpump has no warranty and i'm surely not going to buy another one.i can buy 3 gmb pumps for the price of one hesco and at least they have a one year warranty.just want'ing to hear anybody else's experinces with hesco.

HOrnbrod Posted May 12, 2011 Share Posted May 12, 2011 I have a Hesco high flow water pump and t-stat housing along with a Hesco stroker crate engine for over four years now and zero problems with anything. Never heard of anyone else having problems either. :dunno: Hesco does not warranty anything they consider a "performance" part and have always had this policy.

87Warrior Posted May 12, 2011 Share Posted May 12, 2011 Dang, I would be upset too. However, I have only heard positive tings about Hesco. I have been thinking about purchasing some of their parts for my 4.0 rebuild. Subscribed so I can follow this thread. Link to comment Share on other sites More sharing options...
Incommando Posted May 12, 2011 Share Posted May 12, 2011 Hornbrod: I am curious about the Hesco strokers as I have read some conflicting reports. Would you consider the maintenance on the engine higher than average? More than the 3-5K oil change and the occasional tune-up? Do you take any steps for maintaining and tuning your engine that would be considered above average for most engines? I have read some posts "on other forums" flaming them but nobody has any particulars, so I am very suspect of the claims. Link to comment Share on other sites More sharing options...
Motion Offroad Posted May 12, 2011 Share Posted May 12, 2011 We run the Hesco hi-flow t-stat housing and hi-flow waterpump on our stroker in our '89 XJ and have had no issues with it. Link to comment Share on other sites More sharing options...
ratrapp Posted May 12, 2011 Author Share Posted May 12, 2011 i'm not saying there stuff is junk,maybe i just got a bad batch of parts.i was just wondering if anyone else has had bad luck with there products. Link to comment Share on other sites More sharing options...
flint54 Posted May 12, 2011 Share Posted May 12, 2011 Hmmmm, I was just about to pull the "buy" trigger on that water pump, but this thread causes me to pause. Not so much that someone had a problem with one, but because, according to this thread, they do not stand behind the product. I don't consider a water pump with an improved impeller design a "performance" part. At least not in the same vein as a turbo, or NOS, or some such other device that is intended to actually improve the power, not just move some water a bit better. This is troubling me.

Eagle Posted May 13, 2011 Share Posted May 13, 2011 Why would anyone want a water pump that flows MORE coolant than the engine was designed for? Pushing the coolant through the system faster means it has less dwell time in the block to pick up heat, and less dwell time in the radiator to shed heat. Many years ago, when I crewed on a short track modified stock car, just about every team cut the tips off the water pump impellers so they would flow LESS water, to combat overheating due to high RPMs not keeping the water in place long enough to transfer heat.

Why? I was running hotter with the stock pump, especially sitting in traffic w. 100+ degree temps. Short track modified stock cars don't sit in traffic that much. Put the Hesco hi-flow pump in, along with junking the POS mechanical fan for dual electrics, and no more problems in the traffic.

No offense Flint, but it doesn't really matter what you consider a performance part. They have sold thousands of these pumps and it's a must on a built stroker; browse the stroker forums. I doubt it would do anything for a stock engine. One of the big selling points for Hesco is that they DO stand behind their products. That's why they sell more JeeP go fast stuff than anyone else, in spite of their normally higher prices. To the OP, call Hesco, talk to Bennie, or better yet Lee. Explain clearly what happened. Done that? Hornbrod: I am curious about the Hesco strokers as I have read some conflicting reports. Would you consider the maintenance on the engine higher than average?

I have read some posts "on other forums" flaming them but nobody has any particulars, so I am very suspect of the claims. My stroker is a mild build, .030 overbore and a mild grind cam. Very streetable and no more maintenance than a stock engine. I do 3K oil changes and use a high zinc content oil. I've done all the bolt-on mods to allow it to suck and blow better: 99 intake manifold, dual 2.5" exhaust, Unichip, etc. Use the same plugs as the stock engine only one step colder. I have done several dyno runs after all major mods, and consider it mandatory to determine the overall drive train health. It's a very reliable engine (over 30K on it now) and surprises a lot of folks when they realize it's just an inline six. Hesco gets flamed mainly by fools who spend a lot of money for their products, bolt it on their NA engine and then expect a miracle to happen to their junk. Doesn't work that way; you need the whole package. Gotta do your homework on the stroker forums to find out what works and is questionable. :cheers: Link to comment Share on other sites More sharing options...
ratrapp Posted May 13, 2011 Author Share Posted May 13, 2011 i never expected increased power from a water pump.i was needing to replace my leaking pump and simply wanted to upgrade to a better pump.i did call when i noticed the pump was leaking and they said it had no warranty as it was a performance part and that was that.i don't blame them for the t-stat anyway as they don't make the t-stat,just sell them.like i said maybe i got a bad batch of parts and everything else they sell is great but the piece that really got me was the tps adapter.for the price of that little chunk of aluminum they don't even give you longer screws that you need and it won't allow proper tps adjustment without slotting your tps.i wouldn't be mad if it cost $50 and you had to modify it but i think i gave over $120 for it a year and a half ago.for that price it should be perfect.

flint54 Posted February 4, 2013 Share Posted February 4, 2013 Resurrecting an old thread, I ended up buying the Hesco water pump early last year, and it is now very close to failure. It started chirping a few days ago and got progressively louder. With belt off it does not spin smoothly. It has never been run dry. I'll phone them tomorrow and report their response.

HOrnbrod Posted February 4, 2013 Share Posted February 4, 2013 Their response will (should) be: it's a performance product, as such there is no warranty. It's spelled out clearly on their web site. Same for their stroker engines - no warranty. But they sell many more than their competitors. As you know. That being said, I have one on my Hesco stroker now since 05, no problems. No problems with the stroker either. Just lucky I guess. :rolleyes: Link to comment Share on other sites More sharing options...
Stacks Posted February 4, 2013 Share Posted February 4, 2013 Rant on....'GMB' is an abbreviation for JUNK, poor design engineers, whatever you want to call it. Water pumps especially!!! Rant off. Thank you Larry Link to comment Share on other sites More sharing options...
mountainman Posted February 4, 2013 Share Posted February 4, 2013 If its a "performance" part it should outperform and outlive factory stuff. If flints water pump is only 1 year old thats pathetic. Link to comment Share on other sites More sharing options...
Comanche County Posted February 15, 2013 Share Posted February 15, 2013 No water pump is a "performance part". I'd trust Hesco's measurements and tolerances on a crank or any of their stroker kits, blocks, rods, pistons, cranks etc because they build them in house. I don't know if they cast and build their own water pumps in house with home made bearings because they're so cheap when sourced from overseas. IDK? No clue where their WPs come from. But it doesn't matter. Even if they do build their own, a water pump is a throw away part. Just expect it to go bad anytime, regardless of where it comes from...its an easy job to replace one. A WP is a normal maintenance part, unless its made of unobtainium and gold plated there's no reason to cry over one, its just another normal maintenance item. High flow is one thing, but the cooling and volume capacity of the radiator is far more important. Link to comment Share on other sites More sharing options...
Exgrayxj Posted February 15, 2013 Share Posted February 15, 2013 It wasn't the pump for Flint54, guys. He posted a while back it was the balancer rubbing the front cover ... not sure what Hesco had to say to his call ... Link to comment Share on other sites More sharing options...
flint54 Posted February 16, 2013 Share Posted February 16, 2013 Sorry, I switched threads and forgot to follow up on this thread. Exgrayxj said it, the HB was the culprit, and thankfully I did not pester the good folks at Hesco before I had all the facts. My suspicion was flat wrong, as I've learned countless times when chasing noises. This one fooled me too easily. But, I do not agree that WP replacement is routine maintenance, even if it's an easy job. I expect them to last a very long time unless run dry. Tires, batteries, bulbs, filters, fluids, and plugs are the things I don't mind changing regularly. The other failures are an irritation, proportional to the cost and effort.

Then i stumbled across the same thing, no sense in pumping if faster thru the block/rad and not giving it time to cool off. instead i got the hesco tstat housing and a bigger better radiator Link to comment Share on other sites More sharing options...
