ford transit coolant temperature sensor/cylinder head temperature sensor replacement 

The A/C in my 2010 Transit Connect would only work when the ambient atmospheric temperature was in the low 70s, or when I on an open highway. Stil, my A/C was not that cool. The engine temp gauge was showing very low to zero temperature. Once the check engine light came on, and it was showing a bad cylinder head temp. sensor, I changed the sensor, reset the check engine light and all was well again. She starts right wasy. I am getting an accurate temperature read on my gauge and the A/C is once again COLD. If it helps, Amazon sells a 9MM, 11" extra deep, socket. It is an exact fit at 19MM, and a lot longer at 11" than I needed. I bought it as none of my deep sockets would fit. Extra deep socket sets did not include a 19MM size. So, the Amazon socket was a deal. They sell the sockets as an identical pair, so now I can change cylinder head temperature sensors till the cows come home. These sockets were about $25.00 for the pair and got the job done.

I would start with the temp sensor

@@JaboTheMechanicperfect. I think it is because my fans go on and the engine hasn’t even warm up. Plus, it dies on me when I start it. Something about this design ford did isn’t good overall. Coolant level good, oil is nice and brown. So that leaves the sensor. When replaced I’ll come back with the result. Thanks brotha.

What year is your TC? Which engine do you have?

Yes. The metal business end of the sensor lives in the coolant stream in the cylinder head. There will be a squirt of coolant if the engine is warm to hot. Your best bet is to change the sensor on a cold engine.

Jabo used a deep 20MM socket with some lube. I had no trouble using an EXTRA DEEP 19MM socket from Amazon.

You need a 19MM EXTRA DEEP socket. In this video, Jabo used a larger 20MM socket and he said that he had to lube the end to get it on the sensor. You may also have some luck with an EXTRA DEEP 3/4" SAE socket as it is a tiny bit larger than a 19MM socket. if you have a thin wall 3/4", EXTRA DEEP tire lug nut wrench you may get lucky. Your best bet is to get the Amazon 19MM, 11" long, EXTRA DEEP sockets. They sell them as a pair for about $25.00. It beats checking with every auto parts store and flagging down the Snap-on truck!

Do you have hot air when does it over heat

@@JaboTheMechanic I haven't checked recently but I know the heater core was clogged up. Had that unclogged and the gauge did seem to go longer without heating up. But the engine itself doesnt seem to be actually heating up

Your system could be clogged

@@JaboTheMechanic my mechanic put an additional temperature gauge that's direct to the coolant and it never goes past 230. If it were clogged, wouldn't it really be over heating?

230 is pretty high

This video is for a 2010-2013 Ford transit connect with a 2.0 duratec 4cyl gas engine.

@@thishandleisalreadytaken Thanks for responding but I ment changing it in the title (maybe add Make4,5,6 etc) of the vid, cause your reply is not straight away visible for all.
