2001 f150 sup crew 5.4 l ..... the dummy light and gauge read no oil press in cold temps [20's and 30"S} until engine warms up.... sending unit???... use thinner oil ??? I'm using amsoil 10w 30 now. just turned 80k miles and have had no probs except a couple of coils go bad. and have religiously changed oil at 4k mile intervals. Where the "F" is the sending unit ?

Bert

It's on the lower left front of the engine. It has a white/red wire.

Thank you very much ! I think I will start there , and a can of sea foam for a few miles. I have always used 10w30 . Do you know the exact grade of oil recommended?

Bert

Ford recommends 5w20. Amsoil is a good oil for it.

Thanks Bert . I changed the sensor yesterday. $9 at Napa. The sensor is actually on the filter assy. and a bitch if you have big hands. And only has one wire . But it's done, and so far so good. Although it was only 34 deg. in my shop this am. Maybe I should move south ?? PS you might want to take filter off before removing sensor as about 8 oz of oil will run down your arm or the floor if your quick. HE HE

Bert

Glad to hear you got it fixed. Thanks for the update and the information on changing it. The Ford manual says right front and all I've ever seen was on the housings too.
