Re: Stuck thermostat 1989 J70TLCEM Help!!!!!!!!
If you still have the 'old' version of thermostat, a vernaterm in a white housing with 3-fins going into a rubber bushing, replace it with the newer version!!
Should be automatic if you order on the old part number from a dealer. Remember however to change the rubber seal and cup with the new 'plastic' seat that fits the new version.
The new number is 0434137 for the thermostat.
