Cooling System

That sounds like a water pump leaking. In many cases the water pump seal can leak while the truck is parked, but not while it is running. In other cases it may leak when the engine is cold, but not...

Based on your description it sounds like your engine is overheating and the overheating is accompanied by a coolant leak. Coolant leaks can be both a cause and a consequence of overheating. Consequently, once the leak is repaired, your vehicle...

If you are getting a coolant leak behind a manifold then you may have a coolant pipe, hose leak on the intake side of engine or a head gasket or freeze plug leak on the exhaust side of engine. Have...

You're probably low on coolant. Filling the reservoir doesn't really do the trick for filling the cooling system. There is probably air trapped in the cooling system that needs to be bled out. You may be able to do it...

If the vehicle is presently overheating, you want to check, and perhaps just replace, the cooling system thermostat (thermostats are not costly and they do eventually fail), check the radiator for blockages (radiators can be flow tested) and check the...

You seem to be indicating there is a leak, possibly a coolant leak. If so, the leak point(s) in the cooling system should be identified in a leak diagnostic and thence repaired. If perhaps the leak relates to the water...

Be sure not to drive the car if it is overheating because overheating can warp the cylinder head and/or engine block causing costly damage. After repairing the hose, when you refilled the cooling system, if all air was not purged...

Based on what you are describing, typically a Mechanic would look for a faulty water pump, faulty radiator cap, plugged up, or externally obstructed, radiator, and/or non functioning electric cooling fans. However, your description of erratic operation of the temperature...

If you have really found evidence of cooling system blockage(s), then your continued overheating could simply be due to the fact that not all blockages are yet removed. Also, you could have multiple faults, that is blockages plus perhaps a...

I would test for exhaust gas in the coolant which, if present, would mean that there is a head gas leak. If the coolant level is falling slowly over time, that suggests a leak as well and a pressure test...

Try to put the blower on high speed and move the mode to floor or windshield to see if any air is felt or the noise from the motor is heard. If you hear the blower running but still get...

Driving a car with "zero" coolant will destroy the engine within minutes. Even after a coolant leak, though, you have some coolant in the engine and water can sometimes be added to enable one to drive a "short" distance as...

If you have replaced the thermostat and radiator and the engine continues to run hot and cold and temperature is not controlled correctly. You should replace the cooling fan control switch and make sure all the air is removed from...

The first thing to confirm is whether or not the engine operating temperature is in the normal range and whether there is sufficient coolant in the radiator. If, for example, the engine cooling system thermostat is stuck open, and thus...

If it is confirmed (i.e., no false positive) that exhaust gas is present in the coolant, that means one of three things: the head gasket is leaking, the head has a crack in it (not unusual) or the block is...

If the engine has a coolant leak that is not external to the engine or cooling system would not have anything to do with the transmission repairs. You need to have the engine head gaskets and intake manifold checked for...

The engine could have an internal coolant leak and the coolant is being consumed into the motor. This is is you do not see any leaks anywhere on the round or on the engine. I would recommend having a mechanic...

If what you describe is all you had done then I would have to say it may have been on the high side of pricing for parts and labor. I would however need to see the work order to know...

The thermostat is a commonly known part to fail causing the coolant to not flow through the radiator properly causing the engine to overheat. The diagnosis sounds about right and is consistent with a thermostat failing. This can be caused...

If your cooling fan is inoperative, I would start by having a mechanic check the fan for power. If the fan is getting twelve volts but does not work, the fan is faulty. If the fan is not getting battery...
