I would suspect that the heater valve is not working. Locate the in line valve switch on the hot water supply line that usually sits just behind the radiator. Have someone move the cold to hot slide switch inside at the controls and see if the valve moves "opens". If not, the vacuum line that goes to it may have come off. You can manually open the valve too. I believe you have air trapped in the system. Try this: Elevate the front of the van such as on car ramps so that the radiator is sky high over the rest of the vehicle. Remove the rad cap, run the engine with cap off for 30 minutes and continue adding coolant as the air purges. This may take a while but it will work.Because this vehicle is somewhat high profile in the relation of heater core to rad cap this is necessary. I hope this helps you. Mark
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
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
A faulty thermostat in a 2001 BMW 325CI can cause a coolant leak. The coolant may be leaking out a crack in the thermostat or through a warped edge. In some cases the problem may be just a bad gasket and not actually a problem with the thermostat at all.
Could be low on coolant. If the coolant continues to "disappear", you may have a head gasket problem.
It could possibly be a clogged heater core
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
possible head gasket problem this engine was famous for it.
Check your cooling fans in front of the radiator. It could be a relay or fuse to your high speed fan motor. Also, check your coolant temp sensor, antifreeze level, and or thermostat again.
Could be low on coolant or a faulty thermostat.
BDTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature " I have seen this several times this week alone. All three times I replaced the coolant temp sensor and it fixed the customers problem. john f.
What other symptoms besides leaking antifreeze? Where do you see the anti-freeze leaking?
Ok, if you follow the main coolant hose from the radiator to the engine block you will see that before the coolant actually enters the engine block it goes through a plastic housing with two electrical plugs this is where the thermostat is located. One of the two plugs controls the thermostat (if not both). I had a problem with my cooling system ('94 VW Jetta GL III 2.0L) as well and had to find it on my own. I replaced the whole housing for approximately $35 and it fixed my problem.
Check your coolant levels and make sure it is up to level and decent looking...Coolant (in this case) should be a nice Lime green. Engine Thermostat is probably the most likely cause of overheating...It should be replaced if you haven't already.
Check coolant level in RADIATOR when cold When light is blinking turn on heat and see if you have any. If no heat good indication that thermostat is stuck in closed position and needs to be replaced
flush the system and change thermostat,this should fix problem. I flushed mine and i changed coolant and thermostat,it is now fine.
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
Leaking hose? Defective thermostat housing or bad thermostat gasket? Bad water pump or gasket? Leak in radiator? Leak at heater core? Leak at head gasket? Coolant recovery tank?
I hope you replaced the coolant with a 50/50 mix of coolant and water. Pure coolant will overheat and freeze quicker than a mix. You should have replaced the thermostat, and checked the water pump, and fans for proper operation. Also after draining and refill the cooling system, it must be bled properly, which I suspect is your problem. Trapped air in the system will cause the engine to overheat.Answeri had this problem you've got to wait for the water to circulate. just open the cap and pour more water in (i put 2L of water in)
Could be the thermostat it's stock, replace it.
Had the same problem on my 1991 accord. Replace the thermostat, gasket, and radiator cap. Also, get a gallon of coolant if your current coolant has been in there for more than three years. The thermostat is in the engine block. Simply drain coolant, remove the radiator hose from the engine - the hose that goes from the bottom of the radiator into the engine. There may also be a small spount that bolts into the block, remove the bolts and there is the old thermostat.
you probably need to flush system including heater core.AnswerSometimes the metal in the thermostat corrodes and breaks down so the stat stays open, unable to close....causing the engine to run cool at all times and reducing the efficiency of the heater. Remove it and check it. I have the same problem, I replaced thermostat twice, flushed system and replaced sensors, it did not fix problem, still searching for an answer.^^^^ To this guy, its probly your Coolant Temp. sensor.
I have the same problem I am ready to jack the chrysler up and install a Toyota underneath it
either you are not using correct thermostats,or putting them in upside down,or thermostat is NOT the problem
Thermostat may not be opening
I had this problem with my 106 and it turned out that the thermostat was broken.
