Engine Cooling problem
1994 Plymouth Acclaim 4 cyl Front Wheel Drive Automatic 43000 miles
I've got a 94 Ply Acclaim, 43,000 miles. It started to go through big swings in the temperature gauge and then I noticed I was going through a lot of coolant. I checked all the hoses and related systems, and no leaks. Finally the engine started missing badly at idle, and then also on the highway. I pulled the first spark plug and I can see coolant in the cylinder. I did an oil change within the last six weeks and the oil was fine, no coolant in it. I'm thinking head gasket or maybe a cracked block.
Sounds like a head gasket. Pull the head and send it to a machine shop for evaluation. That is a pressure test and magna-flux for cracks. If okay have them surface it. I have yet to see a cracked block as it isn't the weak link. Although a possibility.
