Alright I did look through about 8 pages and can't find what my car is doing exactly. Ok when my car idles it won't put out heat when you give it gas it blows heat. It sounds like a belt to me but not sure. I already changed the thermostat cap. Same problem. Kind of defeats the remote start in winter. Ok my car is a 03 Honda Civic 1.7. 2 Door. And my window on the drivers side stops about quarter of the way down for no reason anyone have that problem? I just got the car and am kind of wondering has plenty of power not missing or anything just need some heat. Thanks for your time all. Apprciate it.

Have you checked your radiator and reserve tank fluid level? Are they both at the correct levels? Was your radiator full when you replaced your radiator cap?

Come on.....Now tell him what causes this.

I didn't want to go right in to it without getting more information. I was just waiting for "the reserve tanks full to the top and there's coolant all over my engine" statement. I know the blowing cold air is another symptom, but he could have air in the system from doing something else he's not telling us. Not likely, but possible.

You can tell him if you'd like.

Nah, I already got my exercise from jumping to conclusions today.

This isn't going to be good is it???? The resivoir tank was full and the radiator was down. Wait no let me guess head gasket??? I"m going to be so pissed if it is but ****. If that what you are leading me to believe I guess I' m calling a buddy to do it errrrr. But wouldn't there be other symptoms?

Ohhh yeah coolant not all over the motor though....

It isn't overheating either I'm so stumped right now........ Waterpump? Headgasket? Errr what to do....

Normal symptoms are:

No heater or weak heater output, (varies with level of coolant in the radiator)
runs hot/overheating (worse as more coolant is pushed out of the radiator)
radiator appears low, while the reservoir appears overflowed.

That's about it, until the symptoms are ignored for too long.




They don't do most of the things that *some people* think blown head gaskets should do.
That's probably why head gaskets are the most common thing people misdiagnose on these.



Oh yeah, congratulations on your purchase of a used car.
Now you know why it was for sale.
LOL

Coolant won't go all over the engine. It only comes out of the reservoir cap if the reservoir overflows. If it started off empty, then it isn't likely to overflow.


To prove a head gasket failed on these: I fill the radiator to the top, then pressurize each cylinder with 170 PSI of air pressure from the shop air lines, and watch what happens to the coolant in the radiator. When the level rises, I found the breach.

Here's the thread that Matt made when his went. Read what he saw in his first post: https://www.civicforums.com/forums/3...ppened-me.html

Sorry man. I felt the same you do now. Fortunately for me, I was able to do the work myself with some advice from ezone.

If you can't get shop air in to the cylinders to test it like ezone can, you can use the item pictured below to look for bubbles coming through the radiator.



Fill and bleed the system as best you can before doing the below.

Fill the funnel with a little coolant and watch for a stream of bubbles coming up through the funnel as the engines running. Manually rev it in the engine bay and see if the bubble activity increases. If you see an increase, one or more of you cylinders is pushing compressed air in to the coolant system.

Good luck with whatever happens. Better to knock it out now before it overheats and warps your head.

I was sure that someone made a video of putting the overflow hose into a container and watching the bubbles come up from it.

Couldn't find the thread.

You mean this one?

You know this forum does have a search function.

 
Rep Power: 519

That's the one.

I DID search too.

My search-fu is weak.
I bow to your superior skills.

 
Rep Power: 187

^ My search keyword was "bubbles". Goes to show my primitive thinking.

 
Rep Power: 519

Reminds me of.....

Did you ever blow Bubbles in the bathtub? He's back in town and wants you to call him.

I know, that was wrong......

 
Rep Power: 187

Yeah, we talked. We're not making bubbles anytime soon.

His heat obviously is running out. Time to refill.

Seriously though, this is the second person this week who bought a Civic with a blown headgasket, what the hell is going on?

 
Rep Power: 519

I wonder if JC Whitney has some of that?

How about kalecoauto.com?
Good salesmen. Poor buyers.

ok I did a pressure test on the coolant system passed great. We did the funnel thing and filled it it worked great that day next day same thing. So today I ordered Head Gasket set as well as a waterpump since I will be right there anyway. Talk about **** me off good thing my buddy likes working on cars for hours on end. I don't know though. So once I get this done What next? Exhaust? Intake? What are the things to do?

 
Rep Power: 519

I'd probably figure out the drivers window problem next. That sounds like it would pizz me off in a hurry.

Did that already it fixed the stupid cable was a jacked up

 
Rep Power: 187

Sorry. I'm a little confused at what you're saying here. Did the funnel thing work and prove the HG was bad or did nothing fail and you're doing the HG job anyways?

It passed the funnel thing until we put a load on it. idiling was fine put load on it bubbles yippy I mean ohhh F@@K.
