I think i remember reading about an "adapter" that mounts between the thermostat housing and the block, which is used as a take off for water to warm the intake; it seems it would be a good place for a coolant sensor...
Is someone actually selling this or is this a home-made thing? If home-made, any advice on making one?

It has 1 or more pipe thread outlets one of which is used for the heater outlet. If there is another opening with a plug in it this can be used for a senser. Most of them had an outlet on top the cyl. head about 1/3way back. Some had a outlet on top the therm housing, but that would not be very suitable for some sensors. If you don't have more then 1 on the intermitiat houseing you might find one from a later engine. When they started putting the emission controls on them they put outlets for coolant sensors.
They say money can't buy happiness. It can buy old Chevy trucks though.

When I mounted the gauge, I put the sender in the left side of the head.
The truck, '65 C10, has green & red lights on the dash, presumably for cold & hot, respectively. I've never seen the green light come on. I might have the wrong temp. switch?

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.1965 Chevy C10 | | | | | Joined: Feb 2000 Posts: 5,210 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,210 | I drilled and tapped a hole in the thermostat housing. Mine had the boss there but it wasn't drilled out. Most temp sensors are between #2 and #3 cylinders in the head. Joe | | |
