Thermostat help

[87911jon]

Hello. After being a Porsche guy for many years, I find myself with no P-cars and two BMW's, an '83 633 (turning him into a track car) and a '95 525 Touring. I need to replace the thermostat in the 525, it's stuck open. Went to the dealer yesterday and bought the updated housing and thermostat. Went to change it last night and did a dry run on whether I could get a wrench/socket on all 4 bolts. I could reach 3 but the 4th bolt was not accessible due to the limited work area. Am I right in thinking I'll need to take the fan blade and housing off? Any help would be greatly appreciated! Jon

Yes you must take the Fanblade off of the car.
You have a 32mm open ended wrench needed.
This put you on the backside of the fan.
You have the pulley of the waterpump blokked.
Than you put the 32mm open ended wrench against the clock on
To make the fan blade com off.
On som cars can it verry hevvy to take the nuth to losse.
