fords4life Posted April 4, 2018 Share Posted April 4, 2018 Wondering where the needle should be on a 302 with a factory 192* thermostat? Before my lower manifold R&R the needle would sit between the N and the O almost all the time. After installing a factory t-stat, I'm now riding between the R and the A depending on ambient and what speed I'm running on the freeway. Wondering if the PO had a lower temp t-stat and all is good, or if I need to be looking into a cooling issue. Anyone know the temp range on the sender?

1986F150Six Posted April 4, 2018 Share Posted April 4, 2018 They vary from truck to truck. See if you can locate someone with an infrared hand-held thermometer and aim it at the base of the thermostat housing, once the engine is up to operating temperature. Be very careful of any moving parts. Link to comment Share on other sites More sharing options...
