Airbubbles in Coolant?

the guy who did my swap told me that there's airbubbles in my system, and that my temperature guage will go all the way to H, but it really isn't at H. I drove home yesterday like that for about a good hour. Scared me for a bit lol. Anyone know how to get these "airbubbles" out? I'm thinking i just have to flush the radiator and put more coolant back in.

park the car on a hill with the front of the car at its highest point. or jack it up in the front. take the radiator cap off. fill. start the engine fill radiator as it goes down untill it stays full. you just need to bleed the system. if you flush it you might put airbubbles or pockets rather back into the system. raising the front of the car will cause the pockets to come closer to the cap. that is why the fill neck is usually the highest point in the coolant system. i reccomend doing this in the morning when the engine is cold. and when you run the engine it has to come all the way up to operating temps because if the thermostat doesn't open it wont do you any good.

Umm - instead of wanking around with hills etc, get the engine to operating temp and then open the bleed valve. Run, topping up as necessary until its all out.

Hills indeed - jesus, who comes up with these ideas? Honda made a bleed valve for a reason

but if it is at normal temp. and you open the bleeder bolt, wont it burn you??

no it wont burn you, your only cracking the bleeder barely open... a bit of air/fluuid comes out and then you close it up again........ it does help if the front end is a bit higher than the rear.... but you dont need a hill to sit on....

:rofl: Thats ghetto! do what sentana said or do a coolant flush, i do them at work all the time, they dont take that long at all

You fucking baby/idiot :grinno:

You use a ring spanner :screwy:

:banghead:

how do you get airbubbles in ur system in the first place?

By dumping the coolant and refilling - there are a lot of angles etc that the coolant has to travel and it wont always get rid of the bubbles unless you run the bleed valve.

Bubbles = increase in temp (air not water pressurising) and also causes cavitation on the pump impeller.

setanta, what the fuck do you mean by that, i asked a simple logical question. maybe my bleeder valve on my 93 civic is different that your 4th gen.

Setenta is no douche bag. maybe he was being sarcastic or somethin. The bleeder valves are the same on our cars and if your worried about burning yourself, just wear a glover or something ya know?

Nah - it was a stupid question and I was being an arsehole.

Why the hell you wouldn't use a spanner - well, it makes sense to me so that you DON'T get burnt - maybe it's not as obvious to jeffsby. The valve is the same on most cars in my experience.

Sorry - stupid question = derision where I come from.

No - I'm not apologising - bite me :D

where's the bleeder on my d16y8? bambam89lx show'd me his in his d15b2, but i dont have a bleeder in the same spot in the y8...hmm...

Follow the pipe lines - it will probably be close to the thermostat housing. Looks like a standard nipple with nut at its base setup.

aight thanks, will do later on today.

Back to the topic at hand.
I got a D16 and the to find the bleeder, follow the TOP hose to the HEAD. It will be the only bolt around their, and it looks like a robot nipple. it take a 10mm wrench I beleve.
