Smile 2000 740il overheating fan not working and

Radiator overheating.

Fan not working.

The light sometimes lights up for Park, Drive etc on the dashboard.

The car jumps when I start it in the morning and drags with little pickup.

Any recommendations for repairs? Thanks.

Overheating: Need more info. Does your gauge tell you it's overheating? Are you spewing coolant somewhere?

Fan: Which fan? Viscous, Aux or HVAC

Do you mean the lights on the cluster do not show the gear selection at times?

Start up: Jumps as in rpm's or the car shakes? Poor performance could be a number of things. Check Engine Light on? Tried to have codes pulled?

The gauge tells me coolant level low. Coolant is leaking from the radiator. When I put water in the radiator and drive the car a short distance and stop the car, the water spills out from the bottom.

The lights on the cluster do not show the gear selection at times.

The car jumps or lunges forward and then slowly moves forward. The check engine light has been on . I am not sure which fan ...It is near the radiator. Thanks.

You really need to isolate the leak and get it fixed. Could he the lower hose or the radiator itself. Timm covers a few of your issues here:

You may or may not have this issue but look at the info in this thread. You need to check the connector on the thermostat, which is attached to you water pump. The 'could' cause your running problem but the big danger is when thermo leaks into this connector, it travels up the loom into the ebox.

Again, find the source of your coolant leak and get your codes read at an auto parts store, if you don't have a reader yourself.

Multiple issues require patience, fix them one at a time in order of relevance. In this case the cooling leak should be taken care of first, auxiliary fan next.

I have an extra MAF that you can use and see if it fixes the problems at start up.
