Electric Water Pumps, for street use - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**jaros44sr** · 07-24-2008, 06:30 AM

I've just read a thread concerning this topic, and am confused(typical) Durability and function are my concern, and it seems they have neither!

I've spent alot of money on this setup w/o checking to see if it works, so now my problem is finding a way to make it work. Has anyone sucessfully done this, for street use.

I also bought an alum. rad., but this doesn't seem to fix the problem either, so what are my choices, any?

Thank you for any input or suggestions, I don't want to go back to a belt driven w/p, but if I have to I will

Define street use. Weekend play toy or daily driver. We have run the CSI pumps on the street with no problems. I don't think I would try it with one that says drag race use only, but I have never had an issue with them. But, be aware that a lot of the electric pumps flow the water too fast and that you have to have a restrictor of some sort in there. Don't just run the thermostat housing with nothing in it. If you run a thermostat, you need to drill a couple of small holes in it to allow some water through. It seems like they were about 1/8", but the instructions usually tell you what to drill. Breaking the bottom of a thermostat off and just running the top plate works about as well as the restrictors that they sell.

for true street use, don't do it.

Not every day use but maybe sometimes, I was worried about the elec. motor taking a dump and I would have no flow. No instructions with it, I will call the manftr. for info. Didn't know about holes

Andy, any reason why?

They arent as reliable and people have been left stranded because of them. A buddy of mine runs a CSR on his DD, but carries a cheapy reman water pump in his trunk with new gaskets incase it dies. $30-40 dollar insurance policy.

That's what I was worried about, I thought I could carry an extra motor, but I would loose all my fluid. Plus all my brackets are set up for this system
