At 82,000 miles my intake manifold has developed a crack. I am trying to gather all the parts I am going to need to replace it, I think I have everything so far except the two sensors that thread into the coolant crossover (one on the pass. side, and one on the drivers side by the T-stat). I doubt they are going to come out of the old manifold, they both look pretty rusty.

So my question is what are these sensors so I can order the replacements, I cant seem to find any info about them.

By the way, this is for a 96 Mercury Grand Marquis, and with mechanical gauges if that helps.

any help is greatly appreciated.

The one on the passengers side is for the gauge and the one on the right is for the fuel injection. Some places call the ECT for the fuel injection the fuel temp sensor. Even if they look rusty, they may still come out and reinstall okay.

Thanks Bert, I would rather have replacements on hand and not need them, than need them and not have them on hand. I am hoping to get this all done in one day, next Friday, because I have the day off and I have a class Saturday morning.

I replaced the manifold today, took about 4 hours. I am glad I got those sensors because when I tried to remove the one on the passenger side from the old manifold it snapped the brass fitting right out of the plastic manifold, it was seized solid to that fitting even though I soaked it with penetrating oil yesterday and let it set overnight.

That was real forward thinking. Glad you're done with it.
