Left rear cylinder head, just below the rocker cover.

Available from SI, SASCO and any number of other Studebaker vendors.

Unhook the sender wire and short the circuit to determine if the problem is the sender or the gage.

Here's the scenario that matches your problem. Rearmost area of the cylinder cooling jacket - where there's the "laziest" flow of coolant - accumulates crud thru the years. Stuff gets REALLY impacted back there and creates a hot spot where that sender resides. Sender reports to you what IT sees, even tho the temp in the working part of the colling system seems normal![:0][xx(]

Cure - remove rear, block drain plugs (threaded pipe plugs) and dig around in there with a screwdriver or some other such tool until water (You'd have a hose running into the radiator while doing this) runs clear of the loosened crud.

Hotspot eliminated - rearmost cylinders grateful to be evenly heated once again and a sender that now sees the temp of the coolant and not just the hot corner.

NAPA's Echlin # TS6460 should be available.

Miscreant at large.

Mr Biggs,
What you say makes sense. Where are these plugs located? Can you get to them without removing anything?
Thanks,
Ken

Ya hafta take the starter off to get to one. On the other side (bank) it should be relatively clear access.

Messy job. Do it outdoors!

While you're under there, check those "freeze Plugs". If they're rusty or leaking, now is the time to replace them. With those removed, you can REALLY get that crud completely blown out. I've adapted a 3/16" piece of copper tubing about 24" long to my garden hose. At "WFO" it really does the job. As the previous poster said it's very messy. I've used a rain suit and a face shield. Our vendors sell brass replacements as well as brass drain plugs. Hope this helps.
