I haven't actually got the temp gauge in yet. But I can tell you this,... I have now replaced my ENTIRE ignition system, and the entire cooling system. And,... it's still overheating. But it doesn't say that it is. And the weird thing is, today I got to work at 9am. When I got off at 3pm, the car was still registering as hot. It wouldn't start. So I popped the hood, felt the engine, and it was slightly warm. Though I suspect that of being caused by the freshly paved parking lot and the outdoor thermometer reading 98. But it fired up immediately after that. I asked around a number of places. Some said check this, check that, blah blah blah. And all of it has been diagnosed and replaced, same issue. The only guy who makes any sense is saying that because the coil is mounted on top of the engine, move it,... and the head gaskets could be rotted, allowing exhaust gas to heat up the coolant.
I have yet to test that theory. He said to remove the belts from the water pump, turn the car on, and when it heats up watch the water in the radiator. If it is moving or bubbling, then it's a head gasket.
He did also mention the starter solenoid,... but I have a BRAND NEW starter. And it just slowly developed the issue. When she does try to start, even after being hot, it has no issues cranking. But the engine can still run crappy if it's too hot. I don't understand one thing, though. If for some reason it is the ignition coil overheating,... could age cause that? Because in my logic it doesn't seem right that the engine should over heat the coil. Especially if it's the stock parts.
