ok, here goes...i have a '95 integra ls motor (odb 1) in my crx that i converted back to obd 0 using the crx engine harness. i thought that the motor was overheating b/c the coolant starts bubbling over into the reserve bottle on the side of the radiator after a few minutes and the climate gague on the cluster reads that its overheating (after about 5-7 minutes). but i know that its not overheating b/c i let it run for 30 minutes and the radiator hoses didnt feel hot enuff for it to be overheating AND my shop hooked up an external climate gauge that lets the coolant pass thru it and it indicated the temp. was normal, my shop also swears that the new OEM head gasket was installed properly....so my question is

#1 why is the coolant bubbling over into the reserve bottle?

#2 what could cause the climate gauge to give a false reading?

#3 could this have anything to do with the sending unit or the temp sensor?

also, im not sure if this could be related to the problem above, but whenever i start the car up for the first time (cold start), it takes me a couple of attempts to get it started. but after i finally get it started and let it run for the first time, every time i start it after that its ok. i was told that this could be due to the temp. sensor..is this true?

thanks a mill.

 

im not sure how they hooked it up but I can think of two reasons.

one, the thermostat is stuck
two, the radiator cap is defective and not letting the coolant flow back into the radiator

 

um i would say sending unit but im not sure why it would bubble over..i would try a new cap and see if that helps you would be supprised how much a new cap could help...

 

1st what radiator are you using
2nd are the fans working
3rd is it overflowing
4rth is not climate gauge is water temp gage.
where is the aftermarket sensor for the water temp gage is located


dont forget that the reservoir is to serve that purpose the cap (09lbs) regulates the
pressure from the system so any excess goes into the reservoir

 

i am using a crx radiator, the fans are rigged up to a switch so i turn them on manually from inside the car, the coolant is bubbling up to the top of the resivoir bottle but does not overflow when i remove the radiator cap...i think you misunderstood the last point....the aftermarket temp gauge was not permanant, it was just a temporary thing used to check the temp of the coolant to see if the gauge cluster temp reading was accurate (which it turned out not to be). there is no thermo b/c i took it out.
