Old man with an old guitar, and a blue note.
In my 66 Polara 383, I recently did a timing chain replacement and installed a new water pump hosing which I cleaned thoroughly and replaced the temp sending unit with one from a1967 and up application, which the stud connector instead of the spade. This also eliminated the jumper wire from the factory to adapt the two harnesses. See photo...
I used a 180 degree T-stat (gates) which came with the used housing but did the hot water test and it opened at 180 degrees.
The car seems to run hotter than normal by the gauge
See photo...
Before all the swapping, the car ran with the temp setting on the R and rarely over the A, now it runs between...well you can see it. Sometimes it gets hotter. It never gets below the A
I checked the antifreeze temp at the top of the radiator with an instant read thermometer, and it reads 160 degrees. There was some air in the system, but a lot has been bled off.
So...is there a resistance difference between the 1966 and 1967 temp sensors?
Is my T-stat working correctly or... ?
The car runs great, but it could it be a timing issue? I have not checked that.
You can see the "top" lettering on the water pump so it should be correct?
Thanks!
Edit: Checked and adjusted timing slightly...seems ok
