i have a 2000 civic ex bone stock maual trans. Car wont stop overheating. Headgasket, water pump, thermostat was replaced. head was milled when headgasket was done along with a pressure and vaccum test. did a coolant flush. cooling fan switch was replaced. after all that car will still overheat with really no difference then before. ideas anyone. this is my dd and i ned this issue gone. thanks

 

So you're overheating this thing daily? Air in system is always the first suspect. How did you bleed the air? It overheats when exactly? Not enough info past "I've been throwing parts at it with no change".

 

No it not being driven since the issue don't wana create damage. System was burped using the open funnel and car running method. And the heat on the car blows hot not just kinda warm.

 

Did the cooling fan kick on while you burped the system?

 

fan does kick on. system was only burped once. need another round of burping and see what happens from there.

 

Yea, try burping it once more making sure the fans kick on and try elevating the front of the car so the air has an easier route to the funnel. And credit to grumble, I believe I saw this trick in one of your other comments somewhere, squeeze the coolant hoses a little bit to release any trapped bubbles. It should help relieve any air still in the system.

 

yea i always do that squeezing the hoses and sometimes thats all it takes to get that pocket to purge. ill give it a try and see what happens.

 

Not sure if this will help but I had the same issues with my 2000 Civic for 6 months and did everything you have done. The cooling fan would come on but not until temps were climbing too high. I bypassed the new fan switch and wired the cooling fan direct to run all the time and my overheating issues have pretty much gone away.

 

^^^Not a correct way to deal with the problem.

 

your motor needs to be at a certain temp to operate correctly. running cold is not what you want.
