About 35000 miles on my 04 MCS. I had no overheating problems of any sort until just a couple of weeks ago. Now my fan runs a lot more, and for the first time ever, the car overheats while idling only, never as long as I'm moving. I JUST had it in for service not three weeks before this started happening. All fuses are okay, so it is not the infamous pwr strng fan.

Ideas?

 

did you check coolant level?

 

I would pull out the thermostat and test it. That's one easy variable to eliminate.

 

Thats my bet, these cars burn/leak coolant at a previously unbelievable rate.

 

I'll put my money on a bad thermostat.

 

^^ that's where im going next if the coolant level is ok.

 

Try bleeding the 2 air bleed screws

 

It is most likely the power steering fan, which has blown your 5 amp fuse under the bonnet. On earlier cars, the fan for the rad is the on the same fuse as the power steering fan.

Look under the fuse cover in the engine compartment, and check the 5 amp fuse. If it is blown, replace it and check your power steering fan for stickiness.

Hope that helps!

Thanks, all. I will check that stuff in sequence and get back.

 

Sounds like it's not the PS fan as all your fuses are ok.
