You might try a prestone super flush out kit to clean all the rust and debris from the cooling system. Then take a garden hose and spray down the coils on the radiator to remove dust and dirt. If the coils are dirty and blocked by dust and dirt it will cause the vehicle to overheat. Last, check your thermostat. If its not opening, it will prevent the circulation of antifreeze through the engine.

My engine overheat when A/C is running on a slow moving traffic or on parking.

I would check and see how much air is actually moving thru the radiator. The fan may not be running fast enough or you may have debris blocking the air flow. Also make sure the system is full of coolant and no air pockets.

Radiator always overheat?

have a compression test done to determine if head gasket or cracks
next have a coolant pressure test done to check for leaks
have a flow test done on the radiator to check for blocked cores
check and bleed any air from the cooling system
if the over heating occurs at lights or in slow traffic check that the fans are coming on
If you have a viscous fan hub (Vehicle not specified ) then the lights and low speeds in traffic the over heating will be the viscous hub.
if it occurs at speed ,check that over drive is engaging
run the fault codes to check that the engine is in tune and no sensors are faulty.

Check engine comes in when engine starts to overheat, which it does in slow traffic. Radiator, fans, water pump are OK.

Did you check/replace the thermostat? Another possible cause may be hair line cracks in the head(s).

I have a 1999 chry town and country van. Replaced radiator fan, thermostat and fan relay fuse and continues to get hot at times. What could be the problem?

IF your sitting in stop and go traffic with the AC on it will over heat and if the water Pump is weak or about to go out it will overheat. Try having the system power flushed and see if that helps and make sure you are using a 50/50 mix of Antifreeze instead of straight water in the radiator. Also try replacing the radiator cap a weak spring in the cap will allow the water into the overflow bottle too soon causing over flow.

My Chrysler 300m (2004), has been overheating, thermostat replaced, new radiator, mew at a loss. it only overheats while idling or in traffic.

Have your hose's checked , Sounds like your hose may be collapsed, this happens when breaks down from presure. Is this don't work JUst turn your heater on and let idle if this keeps from getting hot your heater core is stopped up. Best of luck, Let me know hao it go's,

The car is over heating while sitting still and is fine while in motion the fluids and belts are all good but I recently took it to an auto shop and they suggested that I replace the thermastate and the...

i would check and make sure the cooling fan is operating,if not it will overheat sitting still.a thermostat will cause overheating whether or not it sits still or driving(more so when driving).the same if it has a bad water pump although it may circulate just enough coolant when driving to not overheat with air flow also adding a cooling effect.if you don`t have a leak then i would say the water pump is okay as they usually will leak before causing a overheat problem.make sure the cooling fan is working and the rad does not have anything stopping the air flow over the rad and is not stopping coolant flow in the rad.

Overheats in traffic. The heat does not work. Does

It can be a couple of things....first one is easy.

1. Low engine coolant level. Just remove the cap on the readiator (engine cold) and check the level of your antifreeze. If it is low, replentish it. This could be your problem.

2. Water pump has failed internally. Easy way to check, start your Benz, squeeze the radiator hose while it is running. Better to do this when the engine is cold. If you start to feel pressure in the upper hose, water pump may still be good. Should feel like rushing water going through the hose.

3. Thermostat. Could be a bad thermostat. If you run the heater and there is no heat but you have air flow...could be the thermostat. Bad air blend door actuator could do this also.

Hope this gives you a starting point!

Weird humming noise & over heating while sitting in traffic

The humming is the noise the coolant makes when the car overheats and forces open the relief valve in the radiator cap and flows through the small hose to the recovery bottle., it you had all this work this done only 2 things can cause the issue, one is a problem with the cooling fan, the other is a blown head gasket, which I suspect is the problem, before you flushed the system was the coolant rusted?
