Intake temps HIGH

I took the ty out to run datamaster and after about ten minutes of 30-40mph driving (low to no boost) my intake temps started rising and shortly they were at 100 degrees (high 50's to low 60's when doing the run). I put a paperclip in the A/B terminals on the ALDL and the pump wouldn't run. The fuse was good (behind the alternator). Checked the wires to the pump and had nearly 14 volts :-? Intake was hot as hell to the touch. It's just not adding up here.


IC mods:
Jabsco pump (hotwired)
ATR aux IC
rubber hoses

Have you replaced the metal lines with 3/4" heater hose? If so, you might have a kink in one of your lines. VERY easy to do if you aren't careful. Did you take the cap off the intercooler to see that the coolant wasn't moving around? Did you ground the *right* wire to get the pump to come on? When I replaced my IC pump, it wouldn't run even when connected directly to the battery due to it being locked up. HTH's

I checked my hotwiring job (I used a scotch lock to tap into the yellow wire and grounded) the rubber hoses are all kink free. I drained the coolent today and it all came out, I blew threw the top of the core and all of it came out.
I crawled under there and saw that I had a connector not hooked up, it's got a green wire going into it, I'm pretty sure it's the ic coolent temp sensore that triggers the ecm to run the pump. But, do I need that hooked up when I have it hotwired? Thanks.

If the green wire you are talking about is the one that is above the stock IC pump all by itself, you can leave it disconnected for as long as you own the truck because it doesn't do anything... That is the sensor that was *supposed* to illuminate the "low coolant" idiot light for the IC but, GM decided to not connect it to anything on the other end rendering it useless. Some folks have took the time to make it functional so, it *does* work in some trucks. Based on your report, I would say that your IC pump is DOA :( . Time to give Ron Gregory at: http://www.autoperformanceengineering.com/ a call. HTH's

I'm going to pull the pump and test it, but believe it or not it was working (at least my intake was cold to the touch) befoe I put a fuse in the in the connecter behind the alternator :-?

is it possible that my pump works when it's not fused and doesn't when it's fused? I took the fuse out and the coolent started circulating :-?
I'm so happy that nothing about my truck makes sense :evil:

HAHA, that should be impossible.
