Question about 1991 Honda Civic
The timing belt broke so I had it replaced by a mechanic. This is the second t. belt and the car has 190,000 miles. The mechanic thought the water pump looked fine so I told him not to replace it (dumb on my part). Shortly thereafter, the car started overheating intermittently. I immediately replaced the thermostat. It still overheated intermittently. I next replaced the radiator cap, overflow tank, and finally had the radiator flushed (in that order). After all this the car still overheats. Now the water pump doesn't seem to be leaking nor is it making any unusual noises. At some point during all this I also replaced the fuel filter because once in awhile the car doesn't idle worth a darn and I thought this would fix it. It didn't.
Hi justin my name is brad i see you are haveing a problem and i think i might know the problem. if you have done all of that to your car and it still over heating you might have a blown head gasket one way to check is to pull your thermostat out and fill your coolant leaving the cap off then start you car let it rrun a few minutes and if you see bubbles the radiator its the head gasket even though you wont have coolant in your oil or out the tail pipe. if you check that and ther is no bubbles i have one other spot for you to check ( dont know if you have the 1.5 or 1.6 sohc ) but if you have the 1.6 sohc with the mpfi you should check on the throttle body at the idle air control valve(IAC) you will see two small line`s that have coolant some times on hondas in the 4GEN(88-91) with high millage the line will fill with crud and that can cause a problem.. if you have any other honda needs please let me know
