Coolant plugs?

scaggsj · 03-25-2010, 05:04 AM

I did a search but didnt find what I was looking for so I just put this out there knowing its been anwsered somewhere. I have an 87 7mge auto recently replaced headgasket and the stuff that goes with it. I didnt change the coolant plugs or #3 gasket. This is where Im starting to think I messed up. Cars been running fine but has been losing coolant, its been winter and the only smoke I see seems normal. (Im also running real rich you can smell it) So losing coolant at a slow pace didnt seem to be affecting power or causeing misses, then more recently the loss has gotten worse but still not bad but now its missing. I you get it above 1000 rpms it seems to run alright, again im having air fuel problems. No oil in coolant that I can see and no coolant getting in oil. How do I know if its the coolant plugs and how do if its the passages. I read something about that on one of cres posts.

Thanks Bill but I think we must be atlking about two differant things. The freeze plugs are on the side of the engine the plugs Im talking about are on the head. in between the spark plugs in between the valve covers

You are talking about the 3 plugs between the spark plug holes, because if you are I was working on mine today and was not able to get them out.

I asked at toyota and they said to use a big breaker bar but I had no luck with that so I put rtv on top of the plugs for now. I may try again when the head is back on.
