I'm a new owner of a 1974 2.0. Does anyone have a photo of where the Cylinder Head Temperature sending unit is located on the engine? I have a center console gauge that isn't working and the gauge seems to be fine.

Thanks, Dan.

The gauge is oil temp . Bottom of motor, taco plate with wire coming out.
If real CHT gauge it's aftermarket so the sensor will be on the other end of the wire plugged into the gauge with no stock location.

The stock cht sensor is passenger side rear of motor, just behind the intake manifold bolt on the rear you will see the wire coming out of the head tin.

Usually it is a sensor ring around one of the spark plugs.

Cut off the plug crush washer and replace it with the sender.
2.0 heads are a bit of an clearance issue, but will work if you bend the ring close to plug. On new builds I notch for the sender.

If it's a VDO brand it looks like this. It is made to replace the crush washer under one of the spark plugs. It is usually installed on the #3 plug because that cylinder is known to run the hottest. The wire to the sender is not normal vinyl covered wire it has a braided kind of stiff covering. Where the wire attaches to the circular part of the sender it has to be bent to clear the head.

Update: Installed cylinder head temp sensor, new plugs, wires, cap / rotor. Still sweating fuel from cold start valve, which tested ok and has new gaskets.

Thinking of chucking the whole fuel injection, going to carbs.

Don't do that, you'll regret it at some point.

You can remove the hose that goes to the CSV. Cap the fuel rail port that this hose comes from with a bolt of the appropriate size, or use the hose to semi-permanently mount a fuel pressure gauge in the engine bay.

Or replace the CSV; it's not exactly that expensive...

Dumb Ass Prior/Previous Owner.

Work the bugs out of the FI, it's well worth it.

The FI can be a bit intimidating at first but i can assure you, once you got it sorted you'll be glad you did.

When i had my 1.7L D-jet, it took me several weeks to get all the bugs sorted out from many years of neglect, but once it was done, the engine ran exceptionally smooth.

Plus, you don't have to worry about elevation. No matter how high (or low) you go, it always starts with the first turn of the key.

D-jet may seem pretty complicated at first but I really like it. I put aftermarket injection in my squareback but I want to put the stock D-jet back on when I rebuild the original motor. It's a nice system to drive.
