Oil temp sensor compatibility- numerical gauge

[OldSpool87]

1982 SC. My oil temp gauge is the numerical style and I want to replace the temperature sensing unit in the engine. I am getting conflicting part numbers from Pelican’s catalogue and Porsche PET. I am trying to plan ahead and make an order of parts. Unfortunately, I don’t have access to the car for a while and can’t pull the gauge for more info.

What’s the best way to determine which sender is compatible?

Thank you,

The 82will have a chrome sensor with a 911 part number.
The early sensor is brass and has a 901 part number
The numerics on the dash can be either as there was a time selling both units to install in dash with sender.

Thanks for responding Bruce. Did the ‘82 come stock with a numeric temp gauge? I thought they had the hash mark style temp garage and therefore a different sensor. I guess I’m trying to confirm which sensor is best for a numeric gauge.

Going through the pet it looks like the date stamps is most important
I recall a 77 had numerics and used the later sender.

There was a posting recently about the temperature topping out different depending on the year of application

I know the one on the left was out of a 69 but they’re both early to go with the brass 901 part.

Bruce-

Here’s the gauge I’m trying match the sensor to. I’d pull it an look at the markings, but I won’t be with the car for a few weeks.



Thanks for any insight.

We know the brass one is good for 340 so it will have to be the chrome one that should already be on an 87 930.

You want sender 901.641.632.00. That temp gauge was used from 1974-1977. I'm pretty sure none of the SCs came stock with numbers.

As a double-check, I have the same temp gauge in my 1979. In my case, I bought it aftermarket, and it also came with a 901.641.632.00 sender. It is brass.

Bruce/Mark- thanks for the responses and information. I’ll report back once the job is done.

Hi Mark , I bought mine aftermarket too, I ran into the same conflicting information as OP . I must have guessed wrong

I often wondered if I had the right sender in it.
mine is chrome .. dammit another project...
