What size engine? Are you losing coolant(this may be internal or external)? Is your oil level rising? This is critical to anwer these questions. The 3.1 (if you have it)motor can be tricky. 2 common problems are intake manifold gasket and the water pump. When the water pump leaks on these, it can be difficult to verify. Look for dried coolant spray on the hood or on the passenger side of the radiator in relation to the water pump. Also look for a rusted flat surfaced pulley of the water pump, or try to check for moisture on the inside the pulley-easier said than done.
You may havt bleed off the air that is in the cooling system. Their is a bledder just above the #2 spark plug ( it is a very small bolt that turns ccwise) I t is connected to a solid blck tube that runs horizontily above the front valve cover and connects to the block. Good Luck
The radiator may be plugged. Take it to a radiator shop.
i have replace the thermostat, checked the fans,filled with water and it is still overheating. Very often, the waterpump leaks and stops working only years after it was last replaced. Coolant is probably not flowing from the engine to the radiator to be cooled.
If you have an old ISUZU Trooper, the radiator thermostat may be not working. Therefore, it will not let cool water from the radiator into the hot engine, even if the radiator is full. Have the thermostat checked and replaced, if necessary. Good Luck
If you replaced some of theses already ignore and go down the line # Not enough coolant # Water pump drivebelt defective or out of adjustment # Radiator core blocked or grille restricted # Thermostat faulty # Electric cooling fans blades broken or cracked # Radiator cap not maintaining proper pressure # Ignition timing incorrect
Not sure if these have one but it could be a bad thermostat.
Get your radiator checked, may have blocked core
first of all, do you have the right thermostat? ie: winter, summer. if so i would get the radiator checked, it may be getting pluged.
2 things I can think of which need to be checked: your coolant and your thermostat.
This question is not complete. . Need to know if you've replaced radiator, thermostat, hoses etc. Are you asking this question *after* yo checked the thermostat, changed, added or drained the system?
If it is not losing coolant I would expect a plugged radiator.
Hi have you checked the radiator for blockage if it is blowing water back out the radiator this could be the problem.
We don't know what relay you are referring to. Check your thermostat and radiator fan. Fluch out your cooling system.
you need to remove the fan the thermostat and the thermostat housing, and the water pump pully and belt. Also you will need to remove the radiator hoses, these should be checked for any holes and replaced if needed.
it could be your thermostat on the radiator. if it is then you could be causing some severe damage to the engine and radiator. i recommend that you take it in to be checked out. a simple problem like that can lead to something far more damaging and expensive in the long run if let go.
Thermostat possibly installed upside down. Also a possible clogged radiator. we have had the same problems. replaced water pump thermo 3 times flushed sys twice repaired radiator,replaced hoses even left thermo out and still overheating help me too PLEASE!!!!! If you replaced the head gasket, it may not be installed in properly. I.E. coolant passages blocked by gasket. Could be air locked. I had this problem with a 1995 Grand Am. Get yourself a repair manual and follow the entire procedure to bleed all air in the cooling system. Some vehicles have a bleeder valve between the water pump and thermostat housing.
im having the same problem with my 1994 I've replaced the heater core,thermostat,radiator,i checked the coolant, and it's not over heating or nothing and still no heat lol
You didn't say anything about changing the thermostat....and when you changed the head gasket did you have the head checked for cracks....But first, be sure that the fan comes on and maybe back-flush the radiator. AND when you fill it with coolant be sure to get all the air out.
Why is YOUR MB overheating? There are plenty of reasons why, so you should check to see if there is/are: 1. enough water/coolant in the system. 2. leaks....hoses, radiator, seals at the thermostat and water pump. 3. working thermostat 4. working temp sending unit. 5. fluid on the interior foot areas 6. good heater core 7. head gasket leakage Now, is this overheating constant? Is the overheating only when you're at an idle? You would need to check the fan clutch...these go bad all the time and cause overheating. You would need to check the electric fan. Have you checked the radiator for leaks or clogs? If you have the original factory radiator still in the car, chances are it's clogged up
changing the valve cover gasket will not fix an over heating problem u need to check out the cooling system. Radiator, water pump, hoses, belts
If the engine is overheating, it is most likely one of three things: 1. It could be that the coolant pump is not working 2. There may be a leak or obstruction somewhere in the radiator, heater core, engine coolant channels, or one of the various tubes connecting them 3. after a while, the thermostat that controls the flow of coolant to the engine may give out and need to be replaced. This is the least costly repair to make and should be checked fore first.
Have you checked your thermostat?
have the engine timing checked. if the timing is wrong the engine will overheat, are you loosing coolant?is the fan working, is the water pump working?
The car is overheating. Possibly the thermostat is stuck closed. Have it checked by a mechanic.
Was the gasket replaced? Have you checked the hose and the heater core. Is everything tightened down?
