The latest on my bizarre overheating prob, with no tstat-she still overheated
#16
if you hear gurgling, then there is air in the system somewhere, like already stated. Try the air bleeder screw on the thermostat cover...u just start the car and unscrew it untill air stops coming out and water starts coming...dont unscrew it too much our you will get water everywhere...just enough to bleed the air out
honestly, the air doesnt sound like the problem...most of the time an air bubble in the system will only cause overheating because the air is blocking water from getting to the thermostat, thus, keeping it from opening, and the car overheats...but without a termostat in place, that doesnt make much sence...im going with bad or mis-wired water pump.

How do you have yours wired? I followed some online instructions that I found through this webpage..

My positive for the waterpump goes directly to that lil red plastic housing for positive connections by the battery, with the lil flip lid on it.
since my car is going to be put away soon i'll recheck how I have it wired, because it goes to a relay then to my fuse box that is spose to turn it on with accessories....so once you turn the key forward but before starting it.
Its strange though that it would only act up now after being there for 2 years.....

Make sure the coolant crossover tubes which screw into the rear of the cylinder heads are not clogged/obstructed/leaking. this is a long shot but highly probable in the event the CSI pump is functioning properly

I had a problem with my CSI pump similar to what you are describing. It stopped one day when driving home. A couple of other times, it had overheated rapidly with no explanation. Like you, I went through all the mechanical stuff and made sure to bleed the coolant.
I could not hear it running, but my indicator light said the pump was still getting power. After checking all the wiring to the pump, it was getting power, but still not running. I started jiggling the wires, and the pump started running again. After I jiggled them some more, it stopped. You could hear the pump speeding up and slowing down as I moved the wires. I moved each part of the wiring carefully to try to locate where the wiring was bad.
It looked like it was right at the pump housing that something was loose. So, I called CSI and asked them. They said the wiring might be bad, but that there was no way to tell without disassembling the pump. So, I paid to have them send me a new one and just swapped it out. I sent them back the old one for a refund with an explanation of the problem.
No more overheating...
