temp sending adapter
5 months ago i put a new stewart warner mechanical temp gauge in my truck. I haven't driven the truck since, i have idled it about 2 hours total.
today when putting in a new water pump, i pulled the thermostat to block housing and i noticed a large amount of white crumbly stuff growing from the area where the adapter for the probe meets the block. It had almost encircled the lower half of the probe. i didnt think to take a picture. I am sure this is corrosion, the adapter, from the s/w kit, is plated steel, the housing is the original steel housing, so how do i get so much corrosion so quick and how can i avoid it.

Re: temp sending adapter
Make sure all the ground wires are good. Block to frame, block to cab, battery ground to block. Try using distilled water rather than tap water in the cooling system...

Re: temp sending adapter
Distilled water will most likely fix it . Tap water has a lot of chemicals in it and will do what you say . It will also plug up the radiator . Been doing this for years in all my rides and the systems still looks good .

Re: temp sending adapter
I didn't think that grounds would make a difference with a mechanical gauge , but i am having some ground issues with my lights so i will try better grounding. In the almost 50 years my truck has only had battery to block, and battery to radiator support grounds.
I do know that distilled water is best, but i have been using tap water for awhile, with 50/50 anti freeze and havent had corrosion in the radiator, thats why i was so surprised at the quick growth of corrosion at this spot. thanks all.

I used about 4 new ground strap on my 68 to eliminate gremlins in the rear tail lights and gauges. I put a grnd strap from bed to frame, one from frame to cab, a new one on engine to cab, radiator support to frame. I may have used another one for good measure but don't remember where.

I think a ground strap kit is on my list of things to do.
