I have a 1994 F150 XL SC with 5.0L with manual transmission.

Contrary to seeming convention, I have 2 two-wire coolant temperature sensors.

Can someone give me the part numbers of both styles I have - the one on the standpipe near the base of the distributor and the other on the drivers side manifold near the front (which normally has the one-wire sender for the dash gage).

I've attached pics of both styles.

 

1st is ECT (coolant) that ECU uses for calculations, 2nd is ACT sensor (intake air temp).

You still have a 1 wire temp gauge for gauge.

Don't buy the cheapest ones. Go to your Ford dealer and get good ones.

 

Oh by all means get Motorcraft... if one can, but it ai'nt always available OR affordable.

Exercise was to show that parts are available & what he has ai'nt unique.

 

and rock auto has them both (motorcraft), so you are not at the mercy of a dealership.

 

I looked at rock first & they had zip in the sensors alone, so WTF?

At any rate he HAS 2 wire sensors & they are available.

Thank you for the info! I did locate the single wire gage temp sender - it was under a jumble of wires and a bit "south" of the ACT (which I think is also called IAT).
