I have a 95' with 3.1 L engine. We experience what so many others with this engine have..A blown LIM Gasket leading to coolant mixing with the oil in the engine case. So I decided to do the job myself with the felpro gasket fix and I even changed out the oil pump shaft o-ring, thermostat, plugs, and valve cover gaskets. Everything went well, the gaskets are holding up, no leaks, and the oil looks clean (not milky). So I decided to test drive it and every thing was going good until after getting on the freeway the temperature spiked. I pulled over and had a look and saw that the heater hose coupler which is attached to the LIM (near thermostat housing) was snapped right at the LIM/coupler junction. In other words, the coupler threads are still in the LIM case. The coupler looked corroded but I decided not to replace it as it was working fine before plus I didn't know if it was a factory only item. Is this "break" the cause of the over heating? I did flush the coolant as well as did an oil change prior to starting the car up but I didn't bleed any air out. The coolant reservoir is full and not being drawn back into the radiator and it bubbles after overheating with the car off. How can I fix this temporarily? I had to abandon my vehicle at a 24 hr restaurant in hopes that it wouldn't get towed over night. Any suggestion will be greatly appreciated. BTW, I just ordered the Lisle heater hose coupler removal tool to fix this problem.
