My guage has read low for many years now and thought I'd investigate
further and perhaps try a new sender.
The guage has three temps: [ 100 | 210 | 250 ] equaly spaced, 210 dead
in the middle and a hash mark between each #. I always run a standard
195F TStat (changed a couple few times in the life of the car). I'm
pretty sure the water temp is running 195+ish.
For as long as I can remember the needle is always right on the hash
mark halfway between 100 and 210.
Is that normal? Or would that be registering about 155F? My experience
with a couple of older GMs with factory guage is that w/ age they have
read low and can be fixed with a new (and correct) sending unit.
I picked up a Wells (TU66) at Autozone. But once home noticed that it
has a spade connector. The original has a round connector (not a
barrel) that the connector slides over from the side.
I'm willing to cut off the factory wire connector and add a common
spade female connector to the wire. But I'm curious if anyone has had
any issues with calibration on replacement sending units.
Part of the reason I ask is that I've had challenges in the past
finding correctly calibrated senders on older Chevys from 60s 70s w
gauges - Delco service replacement senders being particularly
innaccurate before finding one that was calibrated correctly.
