1990 Oil Temp Sending Unit?
Hello
I’m having a hard time finding this part. To date, i’ve been sent the wrong part (1 or 2 terminal) twice rather than the correct 3-terminal part.
Does anyone know of a reliable substitute?
Thanks in advance for your help!

Thrre are 2 oil sender/ switch units. 1 is large and for the oil gauge 1 terminal the other fuel pump and oil light.3 terminals and smaller. Most parts stores should stock it.

OP is looking for OIL TEMP!!!! For a '90 the GM# 10096136 or equivalent from a 'local' auto parts store should do.

Yup, most folks see “oil” and think “pressure” but what I need is the oil temp unit.
So far, both of the delivered “equivalents” have been wrong.
Surprised no aftermarket company has built one since the same part number covers a number of GM models.
One guy reported that he damaged his block because the part he used had non-tapered threads.
It’s been suprisingly hard to source.

Be careful....late l98 dash clusters are weak at best. They’re not linear and the readings can’t really be trusted.
Example- my rpms are actually 400-500 lower than the dash says.
My oil temp reads 100 at cold and 105 at operating temp
coolant temp works but not linear
lcd goes a little wonky over bumps sometimes then comes back
key chime / lights reminder only works when it’s really hot in the cab and the solder expands a little.
We are dealing with typical GM stuff that they still had problems solving 15 plus years later.
