Check for possible air flow restriction to the radiatior. Anything stuck in the cooling fins to cause a blockage. Also check the cooling fan to see if it is working properly. To check the fan (while engine is cold) turn the blades on fan, if the blades do not turn freely then the fan is at fault.Grasp the fan on both sides and rock the fan checking for any excessive bearing play (wobble). To check the fan after the truck has warmed up, turn the ignition off andd disconnect negative wire from battery. Turn the fan by hand, some resistance should be felt. If the fan turnes easily, replace the fan. Hope this will help you.

My 2001 pt cruiser limited over heated. It has already had a new radiator and both fans replaced with in the year. Should i now replace the water pump which is the original?


Overheating is caused by:
1. plugged radiator core
2. Wrong mix of water and coolant.
3. Low coolant level.
4. stuck thermostat
5. hoses collapsing.
6. Air lock in system
7. Bad fins on water pump.

How do i replace water pump on a 2003 cadillac cts n hw do i knw if its no good


Removing the timing chain cover to gain access to the water pump is a tedious job. Consider ruling out other causes such as a defechive coolant sensing unit which is relatively commom. Can you leave your hand on the radiator cap or is too hot?

2003 nissan sentra no heat, over heating


If the engine has overheated, chances are pretty good that you now have a warped or cracked cylinder head and a blown head gasket. Those engines are very unforgiving when it comes to being overheated.

Car is overheating. Flushed three times--no improvemrnt. Can run pretty well with heater on and windows open. Doesn't heat up at idle speed. Someone suggested a loose fan belt but it is hard to...


There are 3 common reasons for a car over-heating:
  • lack of coolant due to a leaking radiator hose
  • clogged thermostat-fails to open to allow more coolant from entering the the system
  • bad water pump- although most bad water pumps tend to leak, it's possible to have a bad bearing inside the water pump which in turn would fail to adequately circulate coolant

2004 dodge ram overheating??


Hi,
Engine overheating?
1. Coolant level at cold
2. Coolant leak check for loss of, during "not hot" running condition. (water pump, hoses)
3. Replace the thermostat. It's inexpensive and easy enough to do.

Hope this helps... Good luck!

2.3l ranger keeps overheating, been through two radiators already.


Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

Overheating


Hi,
If the car is overheating it could be due to a thermostat which is stuck in the closed position, a failed water pump or just a slack belt driving it. I think there will be a "little" tube carrying coolant from the engine to the coolant expansion tank, and if you run the engine with the filler cap removed you should see water coming through that pipe IF the rump is running. A failed water pump will not necessarily leak, it just won't pump the water round the engine.

Always take care when dealing with a pressurised cooling system on an overheating engine - the water may well be above boiling point.

If you run the engine without coolant the cylinder head may well warp and repair bill will be huge.

Hope this helps you a bit. D

I have an overheating problem.what could be wrong


Overheating can be casued by a few things.

1)Thermostat
2)Water pump
3)Dirty coolant clogging the pump

A thermostat is the cheapest part to replace, a thermostat opens and closes allowing coolant into the motor as needed to keep it cool, if it gets stuck closed then it doesn't allow any coolant into the motor thus overheating.

A water pump is what pumps your coolant around the system, and if this goes no coolant moves thus overheating. Usually when these go bad they leak coolant and are also noisy when bad.

Lastly could be bad or dirty coolant, a coolant flush can take care of this.

If I were you I would start with the thermostat followed by the coolant flush, both of these can be done in your driveway.

Hope this helps
