i installed the stock intake back in. a lot of coolant spilt out because i couldn't catch the line fast enough.

thing is, i let my car sit over night then filled the radiator and over flow bottle in the morning. now even after a week or so im still losing coolant.

say i let it sit over night, fill it up in the morning and leave. i let it sit again over night and it will be low again (the radiator, not the over flow bottle) the next morning and its about 1-2 cap fulls low. the over flow bottle just rises some after i drive, but when it cools down it goes back to exactly where it was.

no leaks and the lines are correct.

help

 

are you running hot?

 

no overheating at all

 

before with the cold air intake it wasnt loosing any coolant at all. at first i thought it was just cuz i spilt some coolant when installing it back on that i just needed to fill it up still. but its been about a week.

 

are you just noticing the level of coolant when checking the resevoir/radiator? or is there actually a leak that you notice when parked or otherwise?

no leaks. im checking both the bottle and radiator.

 

Sounds like an air bubble if your reservoir level keeps changing, but in theory, it sucks coolant in and out and the level should not change when the car has been sitting (under equal conditions).

To test for sure, go out to shucks and buy a coolant system pressure checker and pump it a few times, you should see stuff leaking out if it is actually leaking. If not and coolant is simply disappearing, its not related to the intake installation (most likely an internal engine issue, like failed head gasket).

 

how could switching intakes cause a failing head gasket?

It shouldn't, didn't say it would cause it. But if coolant is disappearing and it isn't leaking, its evaporating

 

If you lost track of how much coolant is in there, drain the whole thing and put correct amount in and see what happens.

 

Just had a thought....before this happened I took in to the dealer for a tsb (suspension clunk) but they couldn't "replicate" it. They said the tech drove it around or what ever to hear the sound....note this is when I still had my CAI on....

Could it be that they could've ragged on it to cause this to happen? I mean, that is the only thing I can think of....

 

Coolant circulates thru your motor, could just be that.

so your saying its normal? why does the manual say coolant level is supposed to be at the top of the neck when cold?

 

Are you checking the levels in exact same conditions? Check it in the morning when 100% cold for 2 days.

yes like i said, i let the car sit and check in the morning for the past week.

to be specific, the sits in the garage at like 3pm and it doesnt move till the morning.

 

what the hell happened to 8thcivic? the site has been down since i checked this morning

 

Anyone know how much pressure you need to pump on a pressure tester?

The air bubble sounds most likely. The air bubble will expand when the car get's hot, allowing less fluid to be added. Once the car cools, the air bubble shrinks so you can add more fluid. If you have the system flushed (which is done under pressure), that will remove the bubble. If you don't, the bubble to hang around in the system for months.

You fill when cold, the engine gets hot and dumps into the overfill, then the bubble shrinks and you can add fluid again.

Good Luck.

Do I really have to flush it? I just bleed it and there were quite a bit of air bubbles. We'll see
