Correct temp sensor
 Can anyone help me and tell me the correct temp sensor I need to use for my 68.. The motor is a newer motor with center mount heads and the sensor that was on that motor makes the temp gauge go almost all the way to hot but I know te motor isn't overheating. I don't even mind having to run a reducer/bushing just want my gauge to work properly ... Thanks |

Re: Correct temp sensor
See post 4 in this thread. http://67-72chevytrucks.com/vboard/s...d.php?t=348071 You'd need a correct original sensor to have him machine it to fit your head.

Re: Correct temp sensor
There is actually a resistor on the gauge. You can change that based on the temp sensor your using to compensate for the difference. Here's a pic of it.

Re: Correct temp sensor
The other option would be to take the stock sender and turn it down to the correct size of the head. That's what I did. I run a LY2 4.8L LS truck motor. So my situation I took a stock sender from an 86 Monte Carlo ss the turned it Down on the lathe. But also had to compensate for the resistance difference. You may want to try this sender it's 15$ BWD makes it for the Monte Carlo pn#wt359 I think its 3/8" NPT. If it doesn't work I can turn one down for you.

Re: Correct temp sensor
Gonna try ts-66 temp sensor, one of the old gear heads here at work thinks that sensor may do the trick but if not he said he'd machine the stock temp sensor down to 3/8 and re-thread it .. Thanks for all the info guys

Re: Correct temp sensor
I did not konw that you could change the resistor on the back of the cluster so I bought one form Radio Shack and spliced it inline. Think it was a 10 ohm?

Re: Correct temp sensor
Part # TS66 is a direct bolt in and the truck was running for 15min in my garage and didn't peg out.. Hopefully this helps someone else out .. Still going to have the machinist at work turn the other sensor I have on the lathe as a spare
