1994 nissan sentra overheat
Nissan sentra overheats While Driving Car Runs Hot The most common part that fails when car is overheating is Thermostat, some how it get stuck in one position. I you decide to get the part, get it from a Nissan dealer. The other part I can think of is Coolant Temperature Sensor. Maybe it's not turning on your fans. Check the engine oil, make sure coolant hasn't gotten in. Could be damage to the engine block if coolant and oil mixes. Remove thermostat and see how the cooling fan works. If the thermostat is removed, and if you are sure the fan is operating correctly, there are 4 other things to look at! 1. when you fill the cooling system, be sure to bleed it properly. Set the blower to "hot" to eliminate air from the heater core as well. Position the car so that the radiator is at the highest point. 2. Could be a leak in the cooling system. Get the car up to operating temp. and physically check for leaks. Or get a pressure check done...
