I have a 2000 Civic Hatch with a b18c1 swap. My A/C works on my car but whenever i use it and I check my coolant level, the level drops. I have filled my radiator several times and also the resevoir. When i use the A/C and I check my resevoir, the resevoir is empty. This happens all in 1-2 uses of the A/C. If anyone can help me out with this, it would be appreciated. Thanks.

 

but when u have the a/c off, it uses 0 water?

 

exactly, i mean i know its using the coolant of course but the level doesnt drop like when i use my a/c.

 

Dont use your a/c.

 

well the a/c puts alot more stress on your engine causing your engine to leak faster. You should pull your spark plugs and see if they are white. If they are, your burning coolant, and you prolly have a head gasket issue.

 

alright ill check that.

 

Do you see the temperature on the dash gauge rise above normal? You need to carefully look for a leak from the radiator and hoses. Also consider replacing the thermostat and radiator cap and then bleeding the cooling system.

 

the temp gauge on the dash is always at normal but then again i dont drive it when the coolant is almost empty either, im going to check over all the hoses and do a flush because im thinking i might have a leak somewhere that i havent noticed.
