95 honda civic overheating - help anyone??

Mar 25, 2005 3 Replies

Hi, I have a 95 honda civic. I had my temp spike up suddenly once in a while... 2 months later my radiator broke down. I had the radiator changed. car drove ok for a week or so then started spiking up on heat.... going to max. The only way i could control it is by turning on the interior heater to max. as i turn heater to max the temp begins to climb back. Then i changed the thermostat (drained fluid). It ran a little better..... less spikes. But now it's almost predictable.



if i drive on highway wihtout turning on my interior heater the heat will climb to max. again i have to turn on heater to max to cool it down to normal (half way).



I really need help to suggest me what could this be?? The fan is working when i short the wire going to temperature switch. Also if the temp goes up



3/4th i do see the fan running.

anyone with ideas?? I am dreaded that i may need to run heater during summer.



help me pls.

You probably have an air bubble in your system. It could be in your heater core, and those bubbles take a while to dissipate, if ever.

Try running the engine stationary at a couple of K RRM with the radiator cap off. Watch the temperture, because you don't want overheating. When you see the coolant level drop, add more coolant. Eventually you will hear a distinct burb, signalling that th air bubble came out.

Hope that's it Remco

sounds like you have a coolant leak. check all your hoses and if necessary, the water pump "weep" hole. my crx was losing coolant because the water pump seals had gone.

I have to agree, you never mentioned replacing the water pump. If you have at least 100k miles it's time to replace the water pump.
