Re: temp warning light - please help

["Ron Frazier" <frazierx@concentric.net>]

My temp warning light came on (1990 200tqw) because the temp warning switch
connector got water in it and was held in there by the rubber cover.  The
switch is mounted facing downward in the aluminum fitting on the engine head
where the water return hose to the radiator connects to the engine. I dried
the connector and put it back on and it has worked fine since.
