I needed to make an adapter for a water temp gauge so I went and
bought a 35mm galvanized tubing from Home Depot and had my dad weld
on a threaded adapter.
This tube will go between the upper-rad hose (once I cut the hose in 1/2).
The big question is. Will this tubing corrode from coolant over time? I
doubt it will corrode to the point that it will leak but I don’t want like
the metal to slowly deteriorate and pollute the coolant (as whacked as
it may sound).
This is what it looks like on Phil’s KA-T. The piece he has is made by GReddy ($60-$75CAD).
It’s the blue piece you see between his upper rad hose.
THIS IS NOT MY CAR
Here is the adapter my dad made (cost me $4 for the tubing).
The copper piece is the Autometer temperature probe (used by electric gauges):
My dad fabbed some little cylindrical metal piece which he then drilled
and tapped threads onto. He then drilled a hole on the tubing and placed
this metal piece in and welded it on.
I have the same piece to extend one of my coolant hoses when i did the swap, and it turned rust colour, but has not leaked yet, and we are going on 3/4 year.
