SOURCE: 98 328IS OVERHEATING AFTER CHANGING THERMOSTAT

Are you putting the thermostat in correctly? It it will not work backwards.

And to confirm that there isn't a different problem, take the thermostat out all together and see if it overheats.

Engine not fully warming up is not usually caused by the thermostat. Stats usually fail closed, not open.

You will want to check the water temperature sending unit or gauge after verify the water temperature with an external calibrated thermometer. You can attach and insulate the external thermometer to the housing where thermostat is located.


Reply back what you figure out. I will be happy to help you further.

There can be several things that could cause this concern on a LS and coil packs are certainly one of them. However since the problem is more previlant when turning on climate control I would think problem may be the dual climate control valve is shorting out.The e popping up on your gear indicator is telling me that the network is getting knocked off line, kinda like your home computer rebooting during a lightning storm.
You can do a self test on the climate control,use the follwing sequence.
Front Panel DATC Module Display—Retrieve Continuous Diagnostic Trouble Codes (DTCs)
Continuous DTCs are fault codes recorded by the DATC module which have occurred during normal operation. For the DATC module this means that all faults (intermittent or hard) that occur while the module is in an operational state shall be reported as a continuous DTC.

• To retrieve continuous DTCs, press the OFF and PANEL buttons simultaneously, followed by pressing the AUTO button within two seconds.
• The DATC module will report all continuous DTCs to the vacuum fluorescent (VF) display.
• The DATC module will not carry out a self-test; it will only display continuous faults codes which are stored in memory.
• All VF display segments will light if no faults are detected.
• Individual continuous DTCs will be reported with the °C symbol lit.
• DTCs shall be reported as a four-digit DTC (less the alpha character).
• Pressing the front defrost button will exit the retrieve continuous DTCs mode and clear all continuous DTCs from DATC module memory.
• Pressing any other button (other than DEFROST) will exit the retrieve continuous DTCs mode and maintain all continuous DTCs in DATC module memory.
• Upon exit from the retrieve continuous DTCs mode the DATC module returns to operational status. The DATC module executes a hard (cold boot) reset which places the DATC system in the OFF mode.

it is down under the intake manifold. the intake manifold must be removed to get to it. this vehicle is known for developing a vacum leak in the elbow hose that connects to pcv valve, so ive done a few.

check to make sure heat flaps are opened,check fuses for blower motor or check blower motor

Good point above. Does the fan come on?

If you have no heat, you have air in the heater core.

You say the head gasket is ok because yoou have no oil in the water. Many times the head gaqsket blows combustion into the cooling system only. Get the car up to temp with the radiator cap off, put it in gear, hold the brake and load the engine. If you have a lot of bubblls out of the radiator, you have a blow heade gasket or cracked head.

Check the ignitin timing. Old BMW's would overheat in a heart beat with retarded Ignition timing.

My bet is head gasket because the heater core is air bound

good luck
