unplug the two-wire connector between the time delay module and the fan control valve to activate the fan and cool the engine.
Are you sure its the rad? BMW suffered from viscous fan failure. Symptoms were overheating in stationary traffic but ok when driving along.
Low coolant or an inoperative radiator fan.Low coolant or an inoperative radiator fan.
when overheating occurs at highway speeds the cause is usually. a radiator or coolant circulation problem, Check for a restricted or clogged radiator.
radiator plugged.or coolant low
Yes, but indirectly. Without the radiator cap in place, or using a faulty radiator cap, you run the risk of overheating the engine, which can cause head gasket failure.
There are other things at play to keep your engine from overheating and they are cheaper than radiators. First make sure the radiator cooling fan is coming on. Cost to do this "Free" Next you may want to replace the thermostat. It may be stuck closed or partially closed. Cost about $8 and your time. Either of these two will cause overheating and are more likely to be the cause than the radiator. A collapsed radiator hose will cause overheating also but rare. Hope this helps
Overheating ? - Check radiator for water and coolant, and engine for enough oil and not old burnt oil
did you replace radiator hoses i have seen hoses collapse and cause overheating while driving and radiator could be clogged. also did you bleed your cooling system according to owners manual
Did you replace the thermostat, and check the water pump? Does the cooling fan operate as it should? A plugged catalytic converter can cause overheating. If above items check out OK you need to check for leaking head gasket.
Yes. This will cause the water to leak out under pressure and cause overheating. A hole like this should be repaired before driving too far in this vehicle.
Driving with low coolant in the radiator will allow air into the cooling system, and result in overheating. Severe overheating will damage the engine, and could lead to costly repairs. A low coolant reservoir (the plastic bottle) indicates you are loosing fluid somewhere. It's cheaper to find out where, then replace an engine. Caution! NEVER open the radiator on a hot engine. The heated water is well over 200 degrees and under pressure, and could severely burn you. Wait until the engine is cool to the touch and the hoses can be easily squeezed, indicating that the pressure has bled down enough to open the radiator safely.
