Then diagnose it and fix it. There is more than one possible reason why this is happening. Narrowing it down requires diagnosis. Either you have blockage in the coolant lines or passages, a faulty thermostat, a faulty water pump, or a bad belt driving the water pump.


Why does your 1995 dodge 1500 shutoff while driving?

Motors will shut down automatically if they get too hot. Check your coolant levels and your thermostat. If fluid levels are fine then it is probably a bad thermostat. Never add coolant to a warm or over heated motor, it will crack the head or cause other problems. wait until the motor cools down to add coolant.

How do I change a thermostat on a 03Chevy impala?

To change a thermostat on a 2003 Chevy Impala remove the connectors to the battery, wait for the coolant system to be drained and take out the radiator hose.

Attach the radio hose and fill the system with coolant. Put the negative part of the battery cable to the terminal and let the car run for a few minutes before driving.

Your 1997 escort only heats when you are not driving?

Chances are your thermostat is stuck open. Your cars thermostat sits in a coolant passage. When the car is running your coolant begins to heat up, and at a certain temperature your thermostat opens up and lets coolant flow to the radiator to dispel the heat of the engine to the air. When your thermostat is stuck open, instead of the coolant staying in the engine until it heats up it is constantly circulating through the radiator transferring heat to the atmosphere. When your cars sits still it heats up because the amount of air passing through the radiator is minimal, but as you begin to drive the air flow is increased.


When to change thermostat 1998 Honda Accord?

Ideally, a thermostat should be changed before it fails or begins to fail. Personally I would change it every five or six years or so, with normal driving.


Why do you not heat in a 2000 Mercury Sable after changing the thermostat?

If this happened immediately after changing the thermostat, then the most likely problem is the thermostat was installed backwards.The spring side of the thermostat faces the engine. It's the spring that is reacting to the coolant temperature and driving the valve to open/close.When the thermostat cannot open, that prevents any coolant from ever getting to the heater core. Thus, you shiver a lot!Pop it out, flip it over and you should be all sorts of warm and cozy.See "Related Questions" below for more


Does the coolant temp sensor in your 1997 Cadillac deville cause the readings on the dash cluster to fluctuate between high and low degrees constantly while driving?
