I'm using a Honda Civic LXI bought in 1997. In 2004 and 2005, the temperature gauge would just continue to rise until it almost reaches the redline, then goes back down to midlevel after some time. There seemed to be no set pattern when this would happen. Sometimes it does while I'm driving, sometimes days would pass when my drive seems hassle free.

In both instances, the problem was traced to a worn out thermostat and thermostat valve, and these parts were replaced then.

Last Friday, it happened again, and I'm almost sure this time that the thermostat and thermostat valve are worn out again.

When the problem was being diagnosed and fixed previously, some people suggested to me that I would be better off having those two parts removed from the engine altogether.

Has anybody had the same problem with their civic and were successful in removing these parts? Share naman po sila ng experience nila.

Sir Speedyfix and others, your thoughts are highly appreciated.

Thank you very much in advance!!!
The purpose of thermostat is to get the engine up to maintain the optimal temp., w/o it can cause you too much gas since your car is lot cooler. Do not remove this into the cooling system.
You should find out the temperature of the thermostat that was originally installed in the car (ask your honda parts dealer)and stick with that and make sure to replace the the old coolant w/ fresh 50/50 coolant.
