1994 Jeep Cherokee Sport, 4 L inline 6. Bought it with 98K original miles recently. Took it and had the oil changed, the radiator flushed, 2 of the 3 transfer cases serviced, wipers replaced, yada, yada. The stuff you do when you buy a new used car. Drove it about 200 miles, and it overheated so that the whole thing sounded like it was falling apart in a Portland traffic jam like I've never seen before. shut it down and had it towed. Replaced the thermostat
and the temperature sensor, flushed out the radiator again, had the electrical fan checked, then nursed it back home. As long as I drive it constantly, the temp guage reads just under half way. But if I get in a traffic jam, or stop and go traffic, the temp starts climbing like crazy. Don't want to hurt the car, but not sure what to do. Should also mention that original owner had the radiator replaced. I'm told that maybe flushing the system caused gunk to break loose from the heater core, and thus almost immediately dirtied the coolant. ???
JA: Have you checked the connectors on the sensor itself? It's important that they not be loose or corroded. Are you hoping to fix this yourself? What have you tried so far? What confuses you?
Customer: No haven't done that. Really want to try and do this myself, and learn, because I'm not really a mechanic.
JA: Anything else you think the mechanic should know?
Customer: Not that I can think of.
