For model year '86 and '87, the thermoswitch in the radiator tank for the cooling fans can be mounted in one of two ways:
1.
Thermoswitch into plastic threads or, 2. Thermoswitch into threaded brass insert.
When repairing, proceed as follows:
1.
To avoid breakage of the plastic threads in the radiator tank, always use fiber washer Part Number 900 123 012 70 (arrow A) and torque
thermoswitch to 20 N-m (14 ft. lbs.).
2.
On radiators with threaded brass insert, use fiber washer Part Number 900 123 012 70 (arrow A) and torque thermoswitch to 28 N-m (20 ft. lbs.).
Radiators with threaded brass inserts are installed in production as of the following VIN's:
92HN451193 94HN471588 94HN450798 95HN150140
Use fiber washer Part Number 900 123 012 70 (arrow A) when repairing leaks or replacing thermoswitches on older models. Metal sealing rings must no
longer be used.
