low temp on gauge,2.3 engine 2002
Hello all,i'm new here and havent had much time to navigate around yet,looks like a great resource.The problem that I have appears to be either a malfunctioning temp gauge or sensor,or possibly a stuck thermostat.The gauge does not read above the "cool" mark even after the engine is warmed up.(half hour of freeway driving,moderate outside temp) This just appears to have started since Friday,before it worked normally.The gage appears to work since the temp rises slightly when I am idling,but not to where it used to,about in the middle of the gauge.I have not worked on the cooling system recently.Any thoughts or help would be appreciated.I am looking for a 2002 workshop manual to buy if someone can help with that.
Thanks, Jim McGuinness

You might replace your thermastat like you said. If the thermastat is stuck it would stay open and never let close when the engine is cold. The good news is thermastats are easy to repalce and cheap to buy. Like $4.

Hello all, thanks for the replies.Unfortunately, I have the engine that the thermostat lists at $230.00. It is part of a housing assembly that mounts to the side of the engine down by the lower hose.I had a tough time even finding the location since even the local dealer doesnt have an exploded view of it on their computer.Jim

Re: low temp on gauge,2.3 engine 2002
sounds just like the thermostat is stuck open. dont mean to jack your thread but did you say a thermostat for your vehicle ran $230? bear with me as this is the first ford i ever owned but i must be missing something here.

Re: low temp on gauge,2.3 engine 2002
The thermostat is built into a housing with the sensor is the reason it is so expensive.

Yeap. I think some guy from the forum found a great deal on ebay. IIRC, it was for 60 bucks.

This is one of these "what were they thinking!" when they designed it.
Are all 2.3L thermostats made that way?
I sure hope mine last a very long time if that is the case.

Re: low temp on gauge,2.3 engine 2002
I think all of the 2.3 Duratec have a tstat housing.
Mine is the original one. Last year, I removed the tstat and sanded it with a small wire brush and it started working just fine. You can remove the tstat from the housing (like I did, and it can be a pita). Ford won't sell you just the tstat.

Any info on this mysterious "electronic body module"?
Ford ended this special thermostat in 05 or 06 and replaced it with simple thermostats, to bad they missed the boat and didn't offer a fix for 02-05 models. :bastards:
