coolant leak help

I just bought a 93 with the h23a1. This is my first prelude and I am excited to get into her. It does have a coolant leak coming from the passenger side of the engine. Not too sure where its coming from right now because I don't have possession of the car until tomorrow. Just wondering if anyone has an idea where to start or if there is a common problem with the hoses or gaskets. I plan on replacing the rad and anything that looks worn. Any help would be greatly appreciated.

Thanks

Re: coolant leak help

thats what the pic looks like to me. got a 95 civic that just poors out of there and look exactly the same. its a very simple fix. either order one from honda( highly recommended) or take out the distributor and take the ring to a parts store. 10 min to get off, 10 to put back on. done.

Re: coolant leak help

So i have 2 problems then. Distributor o-ring and also a coolant leak. The guy told me it leaks coolant and the rad was not full when i looked in it. He thought it might be the head gasket but never saw any white smoke out of the tailpipe. No coolant in the oil and no oil in the coolant. I am having it towed tomorrow and will have a good look at it then.

Thanks for the fast response.

Head gasket an easy fix? Please put the crack pipe away! To replace the head gasket you have to remove the timing belt, which means you have to undo the engine mounts, and then delving into that you have to remove the camshafts since the head bolts are under them. I'm not saying its not an enjoyable project, but its not just an "easy fix". It takes some time, and done right you'll need to have the head shaved probably, which means a day at the machine shop.

I've gotta do this since the guy that had the car before me didn't get the head shaved and it just trashed the head gasket again.

To check the head gasket (cold engine please).
Open the radiator fill cap and leave the hood up. Start the car. Get back under the hood and give it some good throttle, and see what the coolant does. If your coolant flows out of the fill port, its the head gasket.

And if your leaking coolant, that is another thing. Park the car over a clean spot of pavement or cardboard with white paper on it. Run it for awhile and see if any coolant gets on the paper.

Re: coolant leak help

Ok. So I got the car today and spent some time looking around the engine. I found my lower Rad hose was kinked pretty bad. Replaced the hose and bled the cooling system. Once it was bled it fixed the surging idle problem. I still have a coolant leak somewhere around the back of the engine that drips near the center and onto the exhaust. Also I had the heat on full while bleeding and it was cold coming out of the vents when the car was fully warm. I guess I will have to get under there and find the leak.
Any ideas where to look?

you put the crack pipe away and learn how to read you self righteous fool. leaking coolant like you said, park it over a clean spot find the leak replace the 30 dollar part 15 minutes done. if it burns it, its a different story meaning its the head gasket.

step 2 learn some forum manners. were all here to learn, not to be belligerent when you read something the wrong way.

your leak is most likely from the intake manifold if indeed the leak is on the back side of the motor. only other place would be the thermostat assembly

Re: coolant leak help

I have a similar leak. Seems to be from the back side of the motor and only when the car is cold and sits over night. Seems odd to me. Thought it was the hose that goes to the heater control, replaced it and it seemed ok until i came out this morning. Hard to tell if it's the thermostat housing or not. I pulled it off previously and cleaned it out and the thermostat is new. Ive replaced the thermostat bypass hose, lower radiator hose and that heater hose. What else could it be? If it's somewhere on the manifold...where should i start looking?

Re: coolant leak help

Mine ended up being a bad head gasket. Wouldn't leak while hot but as the engine cooled or sat overnight it would leak pretty bad. Took it to a shop and had them replace it and all the timing components and water pump while they were in there....not very cheap.but necessary
