temp light switch

[tj5489]

Does anyone have a part # number for the temp light switch? I know that there are three senders. The one I need is the larger diameter one in the drivers side head below the valve cover. Autozone guys keep trying to sell me one for a powerstroke.

That would be the factory overtemp switch. I'd advise you not to replace it with the same part. That switch is set for 242 degrees. TOO HOT. Put in a cooler one. You want to know it is GOING to melt. Not that it HAS melted.

Duralast TU25 at $7? That's the only one listed for my '90 truck under "coolant temperature switch"...

Duralast SU201 at $17 is the gauge sender, listed as "coolant temperature sensor".

Edit: Mel, what other vehicles use the same thread but is set at lower temperature? The switch I mentioned above is also used on 5.0 SEFI cars like Mustangs and Mk7 Lincolns...
