Is the coolant full? Sounds like the heater core is plugged up try flushing your cooling system this may help if not the heater core will need replaced. Or there could be a problem with the heat select switch or vacuum lines under the dash that control the heater door. COULD BE THE BLEND DOOR ACTUATOR. OR BLEND DOOR INOP. OR TEMPSELECT SWITCH Many of Ford�s manual air conditioning systems use an electronic blend door actuator (motor) to control the temperature of the air entering the passenger compartment. The temperature knob on the A/C�Heater control panel is a variable resister (potentiometer) which varies a voltage signal to the motor. This signal determines blend door movement. Complaints of temperature always hot, cold or not changing as the temperature knob is rotated will be caused by one of four problems: 1) bad actuator; 2) bad potentiometer; 3) open or shorted wire(s); 4) broken door. See this site for troubleshooting procedures http://www.4s.com/fourseasons/tech_tips/tech_tips_english/AB356_Ford\'s_Blend_Door_Actuator_02.pdf I had the same problem with my 1998 Ford Ranger and the accumulator hose was disconnected. Replace the hose and it is functional once again.
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
had the same problem with a sibring,took to the garage,they replaced the thermostat and gasket and found a hairline crack in the thermostat housing they replaced the housing and everything was fine then
The sensor may be defective/broken. I would have that checked or replaced.
either you are not using correct thermostats,or putting them in upside down,or thermostat is NOT the problem
are the cooling fans coming on
If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its 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?
I've had the same problem before and after a new thermostat, but have never had a problem with over heating. I have a feeling the gauge is very sensitive.
If the car vibrates when the brakes are applied, it could be a sign that the brakes or rotors need to be checked or replaced. When a problem like this occurs, it is best to get it checked out as soon as possible to avoid worsening the problem.
ask your service station to do a compression test. I had the same problem and replaced all sensors and thermostat but after the test it was found out that there was a crack in the housing holding the thermostat
Did you put the thermostat in backwards? I would check to see where the steam is coming from. I had to change out small hoses for the same problem with mine.
Could be a problem with the wiring from the computer to the sensor.
is it just residue from where the gasket is gone?, if not there is a possibility that the head is cracked, was the head checked to make sure it was not warped? and pressure tested?, also you might have an additional problem, radiator blockage,thermostat stuck or if its the k series the dreaded ballbearing problem, each of these could cause the gasket to go again
Perhaps plugged radiator - have it boiled out or replaced
check your radiator. is it clean or does it need to be replaced? a simple cleaning cured my problem.
Inoperative radiator fans, bad water pump, failed headgasket?
My guess is the head gasket, have same problem. Nightmare
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
Could be the head gasket. Very common problem with this engine and model year Windstar.
I had the same problem with my 98 jimmy I repalaced the water pump have had heat since.
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.
The top radiator hose is above the thermostat. If the top radiator hose is hot, the thermostat is opening. The thermostat is not the problem. Perhaps the radiator is clogged up or the water pump is bad. Look elsewhere.
it should be replaced when it stops doing its job controlling the temperature and replacing the battery does not solve the problem or it is showing a digital error code that tells you it is defective. You may also want to test if it actually is doing its job but the heating or cooling unit may be broken. If you have more than one zone and you know what you are doing, you can switch it with a known working thermostat and see if the problem stays with the zone or it moves with the thermostat. That should tell you if the thermostat is broken or the system related to that zone needs maintenance.
There are a few things that could be causing your 200 BMW 528i to overheat. You may not have the correct mixture of coolant in the vehicle. The problem could also be your thermostat. Have the thermostat checked out to ensure that it is working as it should.
If the engine is taking a long time to warm up or the gauge registers low heat the thermostat probably is stuck open and needs to be replaced. If the engine runs hot check the temperature of the upper radiator hose. If it's not hot the thermostat is stuck closed and should be replaced. If the upper hose is hot it means the thermostat is open and working. Cooling problem could be restricted radiator.
