Mechanical Water Temp Gauge Install Write-Up (1 Viewer)

Just an update on this should anyone follow it in the future:

The 'Steiger' brand upper rad hose adapter was not a good fit. It was too long for the short upper hose and made the hose rub against the Power Steering pump reservoir. I finally changed it out for this one and much better fit.

The autometer mechanical Temp gauge requires a 3/8" NPT hole and the radiator hose ID is 38mm or roughly 1.5".

How's this working for you? Have you made any changes/updates to this setup in the last few years?

Nope. The smaller insert is perfect. The only thing I'd be tempted to change would be to use an Electric gauge instead of the mechanical. Mechanical is more accurate (so I've read), but it's a pain to install. There are a lot of very simple digital elec gauges out there that I have no doubt would work just as well. Plus, those can be adapted to other spots on the head so you don't have to cut into the upper rad hose.

Depends on how much work you want to do.
