Temperature Sender

I have some aftermarket gauges,I believe they are called TPI that I have upgraded to Autometer. The problem is the temp sender of the previous gauges will not come out. Would I be able to reuse the sender with the Autometer gauge. I am hoping that all electrical temp senders are the same. I have not filled up the coolant yet just in case they are not compatible & then I will have to find a way to remove it.

Re: Temperature Sender

They aren't all the same. Whether or not it will work is somewhat of a crap shoot. You could try measuring the cold resistance of your sender and compare it to what came in the box. If they're close the original sensor*might* work. Same is true of any resistance type sensor like oil-pressure.

Sorry, I don't know if they're the same, but why can't you remove the old sensor? Is it threaded into the manifold intake?

It is threaded it & it won't budge. I don't eant to break it off in the head. The sender is screwed into a reducer & neither will budge. I am afraid of breaking off the brass fitting in the manifold.

Re: Temperature Sender

Getting out can turn into a mission and a good chance of damage to the manifold...
Been there done that...
If intending to remove, and was like mine, no matter what sort of penitrating oil u use, or how long....doesnt work

In the end, I smashed drilled out the sensor, then in a drill press slowly drilled out the brass adapter...increasing sizes.
Once I could just start to see the manfold threads, I very carefully removed the top threads so I could get a good accurate start with a thread tap...then very patently tapped the brass out...
I have the tools etc...in retrospect...time, and if had to do it again, I would put the manfold into the local machine shop to put and do in their large drill press.

If the senor is the wrong one...and it does still work...u can always relocate the gauge needle so it reads about 180 to 190 degs in the middle of the gauge.
The gauge needles are pressed on...carefully lift it off....the drop the sensor/manfold into a bucket of water @ req'd temp..hook up electrics to a battery, put a tny spot of silicone sealer on the hole of the needle with a tooth pick and press back on

I use slicone because it holds, and maybe sometme in the future I may have to reset it
using epoxy or similar one cant reset without damage later.

My Spelling is not incorrect...it is creative
