Overheating issue
 

I've checked the water pump and the thermostat but both seem to be in good working order. My problem is there so muc pressure building up that its pushing out all the water in the reservoir causing it to overheat. Anyone have any other suggestions?

Same thing happend with mine, turned out that the water seals around the engine had gone. Rebuild time for me.

damn that sucks, i just got this engine from ray less than 1000 miles on it

jimmyp281,

When you say its overheating, you are seeing the stock gauge go to "H", or do you have an aftermarket temp gauge?

mine overheats only when going up hill over 70 mph and yes the stock thermo goes slighty

i have a pfc and i look at the commander. Its also the water thats causing an issue, i put more in and the pressure just shoots it out. Basicly it wont hold it.

What temps are you seeing?

Are you sure you aren't just overfilling the system? Its designed to expel extra water/coolant.

on the pfc im seeing temps get up to 130. I dont think im over filling it. I didnt put any water in untill my coolant light went on. When the light goes on i put in some water. Drive for a bit like only a block and boom light goes on again.

With temps that high I wouldn't be surprised if your motor was damaged.

I would start by talking out the t-stat and inspecting/testing it. Make sure its working properly. Also, if you suspect a coolant seal failure, you can have your cooling system tested for Hydrocarbons. Its a common test that pretty much any shop can do (or you can buy a tester from most local auto stores).
