It is behind the housing that both the top and bottom radiator hoses are connected to.

Most likely a bad Thermostat or Water Pump. Replace the Thermostat, the cheapest part, and if it still overheats replace the water pump.

I have a 1997 BMW 328i- Left it idling in the driveway for about 10 minutes, and it over heated, and started spewing rad. fluid out of overflow tank- let it cool down, took off up the road, and it...


yes, if the water pump is bad, input hose will be hot output hose will be cool, but that also could mean a bad thermostat.

a way to see if the water pump is pumping coolant is to remove the bleed screw on the thermostat housing and see if coolant spews out.

But it overheats. may as well change out the water pump and get rid of the original plastic impellers. While you're there, replace the thermostat with a 12 degree cooler one and drill 2 3/16" holes 180 degrees from each other in the thermostat.

2.8L motors are sensitive to overheating. you can bust a head gasket this way in no time. Also warp that long cylinder head.

Where is the thremostat located


In BMW 328 To locate the thermostat follow the hose from the right side of the radiator to the motor at that connection there is thermostat.There should be 3 bolts which you will have to remove to take off the thermostat. In BMW 328i The thermostat is located behind the viscous fan and approx 9inches above the center of the fan. The viscous fan drives the water pump and the thermostat housing is just above the water pump at the front of the engine. The thermostat is a one piece unit and is a bit expensive £55 at dealers £42 independent. You will need to remove the viscous fan to get at it there are special spanners for this and its a 30mm socket left hand thread ( screws off clockwise). Thanks. you can rate this solution and show your appreciation.

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

OVERHEATS IF SITTING STAYS OK COOL IF MOVING OVER 40 NO HEATER FA


you can check if the water pump is working by feeling the top rad hose , if it is hot it should circulate into the rad and the rad should be hot at the top and cool at the bottom if the pump is faulty there will be no circulation of hot coolant into the rad. I suspect your head gasket might be blown if you are getting pressure built up in the rad. in that case you will need a new gasket and have your head skimmed

1995 328i Over heating


If the water pump was bad you should hear it or if the bearings were bad, then the serpentine belt would likely fall off. run the car until hot and open the cap for the radiator. If there is pressure then the pump is working. And running without a thermostat just keeps a constant flow iwth no engine temperature regulation. I would put a thermostat in and see how the heater works after that.

Over heating


If your thermostat aint seized shut, its your heater core. You need a new one. Your heater core is another element that makes the antifreeze move in a circular motion. If it aint moving in a circular motion, your car is overheating, meaning that it could be your thermostat, heatercore, or waterpump, but I think that its your heater core. If it is your water pump, your check engine light would come on.
