Oil Temp sending unit question
 

Hello, I have a quick question for the Porsche gurus. The temp sending I removed from my motor is stamped 150C. The one I was given is stamped 200C and it appears to be the correct part number per the Porsche Parts Manual. My gauge has a range from 30-170C (euro car). Does anyone know which unit is the correct one for my gauge application?

Thanks,

Ed,

Do a search.

There are several post on this subject.

Good luck,

Gerry

I did earlier and came up empty. I'll try to reword my search

Ok did the search, nothing. Maybe I wording my search wrong.
Thx

Try this thread http://forums.pelicanparts.com/porsche-911-technical-forum/427076-hot-hot-hot.html if you have a '77 temperature gauge - that seems to be a one-year only part, as the '76 and earlier are different, and so is the SC.

'77, 930 and 3.2 all use the 911 606 112 00 sender.

74-76 and SC use the 911 641 632 00 sender.

Thanks. I just found the parts catalog and it listed the 911.606.11.00 sender to be the correct sender. so I installed the 911.606.112.00 sender and removed the 911.641.632.00 sender. I'll buy an IR thermometer to double check.
This Euro car keeps me on my toes. thanks for info.

Ed,

What did you ever find out here? I'd almost be willing to bet that your gauge readings will be off.

I ran into having a 200C mixed with what I believe to be a gauge designed for the 150C. Doing the math shows that it can be off as much as 60 degrees, so be weary. In essence (using my understanding of the expected outputs, using the 200C sensor and a gauge designed to read the 150C will show things to be coolere than they actually and . . vise versa if you reverse that and use a 150C sender and a gauge calibrated for a 200C input.
