Head Temp Sensor Install Tips/ have any?
 

hey people,

my '71 1.7L needs a Head Temp Sensor changed out.

any suggestions on the best way to pull out old one and install new one?

it seems I have to remove the intake manifold on that side to get a straight shot at the sensor.
it was easy to remove it with the manifold in place, but I cannot for the life of me get a straight shot at the threads to get it started.

you would think "they" would of thought this out a little more.

thanks guys,

look around here, there is directions in the parts table. Basically buy a deep 13mm socket, use a dremel to cut a little slot for tghe wire to pass through and twist.

I prefer to not cut the socket. I like cutting the corner off of an extension (a 3" one works well) to pass the wire out through the square hole in the back of the socket. A slice in the side of the socket works, but it's more work to make and the wire easily gets wrapped around everything.

Since you should only have to do this once in a blue moon, why destroy a tool to do it?

I take the lead and wrap it tightly around a screw driver, making a pig tail. I then take a 13mm deep socket and slide the pigtail with the connector on the inside, into the socket, then the sensor. I have removed and replaced the sensor a dozen times using this method, no problems.

BTW the sensor is canted at about 20 degrees off of perpendicular (towards the rear of the car) That may be contributing to your frustration.

Good luck!

Good tip Herb, I think I will try that next time the blue moon waxes! I did this job a few days ago, and luckily I had a hollow tube with a 13mm hex head that worked great.

BTW, those pesky little make-up mirrors your girlfriend/wife or sig. other has in their purse works great to help see different angles.

First we wash parts in the dish washer, now we are snagging cosmetics from their purse...pretty soon we'll be on the street!

Probably the easiest way to install it is to take off the engine tin, then you can put an offset wrench on the sensor. Although it may be time consuming, it is very straight forward, and will save you a lot of aggravation.

That angled position took me by surprise. I futzed with it for at least an hour until I lost my grip on the socket extension. It just happened to hit the right angle & slide on. A camera would have been great to catch the look on my face:rolleyes: Those Deutschmen thought of everything when putting these little jewels together. Like the little hole that's in the right place for the socket & extension to unscrew the hose clamp for the heater flapper box (if you put the hose clamp in the right position!)
