Coolant Leak. Replaced Water pump and T-Stat.

I have replaced my Degas bottle, my water pump, and my T-stat, but still manage to have a coolant leak. It runs under normal temps but will not hold coolant. It leaks heavily while running, and slightly when off. I am unsure as to where it is coming from. I had a T-stat leak but fixed that. (I already used the search function but cannot seem to find anyone else with this problem, if anyone else has this problem and created a thread. By all means show me) Any help would be greatly appreciated!

Could be the donut gasket/fat o ring between intake manifold and front cover, could be front cover gasket, could be an o ring/gasket in the valley as well. You need to pressure test the coolant system.

Re: Coolant Leak. Replaced Water pump and T-Stat.

i suggest a pressure test and with the degas bottle and small 3/8 line it is an easy task to do

seems like you would have an idea of the proximity of the leak ??

now if it's head gaskets it will push coolant past the cap you can test for that easily also

Thank you! I didn't even think of that! I will try a pressure test tomorrow when I'm off work! I'll post my findings!
