In case anyone has to replace their CHT sensor which is a PITA, you'll have to make some type of tool. I ground down a corner off a 3" extension, and attached a deep socket.

It's much easier to install and uninstall if you remove the decel valve and MPS.

Here's a picture of the extension and socket with the CHT ready to install. I attached the washer to the CHT sensor with a drop of superglue:

That is Slick! It's amazing, I never thought about grinding the corner of the extension. I've alway fenagled it by just using the deep well socket and using the wire with tension to guide the sensor to the hole. you have a cool tool there and now I'm going to make mine. I don't know about you, but I find myself replacing that sensor every couple of years.

How do you know you need to replace the cht

The PO soldered a 1/8w resistor to the old one, and the vibration caused it to snap. I had a NOS one from mark heard so I put that one in place of the old one instead of repairing the wire.

man I hope I don't have to do that -- the 017 part is a pretty rare beast for the 73 2.0L.

Nice tool! What size is that socket? I will be crafting one up myself. Not to hijack, but I suspect I need a new CHT for my 1974 D-Jet and found these on Ebay. Price seems very reasonable. Are these legit?

I believe 13 mm. When I did mine I took a cutting wheel and cut a groove wide enough for the wire to pass through into the corner of a 3" cheapie extension. That way it doesn't weaken the entire corner of the extension (although the're inexpensive) to much.

It's a 13mm deep craftsman socket with a 3" extension from lowes.



Mark Heard has some (914sixer), and he is legit. Send him a PM and he'll hook you up.

thanks Jim, great thread!

A 1/2" plumber's faucet wrench works fine - a couple of bucks at Ace. No grinding, no welding. Can also be used to tighten faucet valves.

Can you post a pic of what it look like? Thanks.

Or,....... you could just stuff the wire in the deep socket and go.

Zactly

but then you don't get to grind anything
