ive been told before with a brief non specific explanation and that doesnt really help me since i dont know all that much. and i did search for it and didnt find anything. so if there is one out there already could some one point me to it?? if not could someone please give me atleast a semi detailed explanation on how to change it, what to remove to get to them?

 

Which o-rings are you talking about? There's quite a few of them. The ones under the beehive oil cooler? The o-rings in the intake manifold? Let us know where the o-rings are and we will be able to help you better.

the ones in the intake manifold

its the same up until you plug the holes.

 

thank you!!! but this is possible without having to take my engine out right?? cause i dont have access to a cherry picker

 

Did you read the link provided?

You don't have to pull the engine to answer your question.

 

+1!

its 6 bolts and 3 cables

 

...and a bunch of slickery green fluid...

 

you may want to plug the holes anyway.

 

it talks about having a carb, i have a 13b. but im assuming its the same thing just minus removing the carb right?

 

There are no coolant o-rings on a Se!

 

If you are leaking coolant on that side then check the 2 coolant hoses that go to the throttle body. 1 goes from the back of the water pump housing and runs in between the throttle body and upper intake manifold to the T/body nipple. The other one runs from top of the rear iron of the engine to the t/body nipple.

 

im totally confused now, ive asked around and even one of my friends (who has an 88) told me it could be an o ring.
and the guy at pineapple racing told me too. http://www.pineappleracing.com/pinea...lications.aspx

so im confused

 

This would probably be a good time for you to describe your car: year, model, build, engine setup, mods if any...

When you said you have a 13B, that led Doc to assume you have a GSL-SE, in which the engine setup is very different as it's fuel-injected. But if you have a non-stock setup or a swapped 13B, you could well have a carb'ed 13B.

A couple photos of your engine compartment and your problem area would also clear things up nicely.

 

He states that he does not have a carb-
it talks about having a carb, i have a 13b. but im assuming its the same thing just minus removing the carb right?

His posts from other threads state that he has a GSL-Se.
Like stated SE's do not have the water o-rings in the intake, end of story!

 

Sorry; just trying to help.

 

The NA 2nd gens don't have them either. Only the 12A and the 13B turbo cars have them.

Are you blowing white smoke, just losing coolant, or what? If you tell us what is going on, then we could better help. Pineapple and your friend may have thought it was the o-rings due to not enough info given to them. If you say you have a 1st gen, most are going to assume 12A.

 

Sorry my statement was not directed at you but the OP.

 

Like a lot of new members instead of using their original thread they start new ones?

your right i do have a gslse. but if my car doesnt have orings, then what is leaking the coolant down to my exhaust manifold area under the heat shield?

its not the hoses. ive checked those multiple times with and without the car running.

 

It's not a matter of if you don't have o-rings, you don't have them!

As far as you leak I have given you the 2 main possibilities.

You have options.

1) Get some coolant dye and put it in your radiator. Napa sells it. Buy the Back light bulb that is used to detect the leak.

2) Have the system pressure tested.

3) Pull the upper intake and T/body and inspect the nipple that is at the rear iron and hose where it attaches to the nipple. Remove the other hose from the goes from the back of the water pump housing to the t/body and inspect it also. Don't know what else to tell you.

 

mk. thanks guys

 

If you don't have a CA-spec car, the sub-zero system is also connected just above the manifold and that could leak small amounts of coolant (the sub-zero setup uses a mix of coolant/water). Not very likely and you probably have a CA spec car since you are in San Diego (CA spec cars didn't have the sub-zero setup), so this isn't likely, but a small possibility.

More likely it is one of the small TB hoses that is leaking or you have a small leak up by the water pump/t-stat and the coolant is blowing back when driving.

Just follow what Doc said and you should be able to find the leak.

 

well thanks for all the help guys. i fixed the little leak. but now i have one hell of an idle problem. i think its a vacuum leak, dont know from where. i rtv'd everything i took apart. soo yeah. any suggestions on how to find the vac leak?

 

What did you take apart and what did you use silicone on? Also what was the leak?
