[QUOTE="chad keene, post: 1021292, member: 68848"] Ok so this is the run down, my thermostat housing started leaking, so decided to replace it. Well before it was replaced even with it seeping, the vehicle never ran hot, so replaced the housing, the sensors, and thermostat, now it shows it's running hot, but here's the issue. Immediately on startup even with the engine dead cold, and the vehicle setting for hours, on startup the temp gauge automatically rises to the middle within 10-20 seconds showing its already up to operating temp, which I don't see how that is even possible, and as you drive it, it gets up near the H mark, not in the red, but gets close to the H within only few minutes of driving maybe 5-10 minutes. Well we have had the coolant system flushed, all new 50/50 mix, radiator coolant system checked for air, fan clutch checked, still same symptom. As I said before the swap we never had any trouble ever with it getting warm, could it be a faulty temperature sensor? How could the engine get up to operating temp so fast within 30 seconds or less? Would a stuck thermostat cause the temperature gauge to rise that quickly? [/QUOTE]
