Default Help?

I took this video right after I drove about thirty miles.


Click the picture

Turn up the sound... I think the reservoir may be overheating and the coolant boils over and comes out from the lid. Should I be worried about this or am I just worrying about nothing?

What is your temp usually at? You will definitely need to get a new overflow bottle.

First of all, I'm not getting the video, just a picture. Second, it's quite possible that you have a blown head gasket. Exhaust gasses escaping into a coolant passage will cause pressure to build in the system. This is commonly noticed when the engine is cold and you start it and after a minute you shut it off and then open the coolant resivor. If you hear air pressure release then it's time to take it to a shop and have it checked.

^^^Eh, I dont think its necessarily indicative of a blown head, its a renix era..they are known for finicky cooling systems. Anyways..I had the same issue with my 88..took a few different steps and never had the problem again, I went ahead and swapped in a new t-stat, replaced upper and lower rad hoses, did a complete flush, and then..replaced the entire reservoir and it solved my problem, I had a small (I mean damn small) crack in the reservoir that was causing the pressure to escape.

First off, replace that chinese crap-cap with one from Napa. 703-1396.
