temp sender
 

(39 standard) I am going to remove my water temp gage from instrument cluster to get repaired (only one not working) I will put in a Aftermarket one while wait for the other to come back. Question is how much water will I lose from the system? Will it be all that is in head, all in hose and head or all in upper radiator to? If its going to be a lot I'll just go ahead and drain the system. What's in there now is fresh. Doug

You don't have to lose any fluid if you use a catch can.
Just drain it to slightly below the level of the sending unit.

Re: temp sender
 

It will drain everything that is equal to or above the height of the sender. As 51 Merc stated, drain the coolant to below the level of the sender.

Thanks.

Well got the old gage out and guess what it said on it. "Made in Industria Argentina." The tube is broken so I guess I need to find an old stock one or get another industria argentina or China one. I see Mac's has them. Saw some used gage clusters on ebay.

Be careful of used clusters. TOO MANY times, idiots just cut the capillary tube to the temp gauge with a pair of dykes, which OF COURSE.....destroys the gauge. DD

Here is a working 37-39 cluster with correct temperature gauge with the capillary tube attached, it shows it cold and all the way to boiling temp. If your interested

I replaced several cap tubes from any after market gauge
to the original. Coil both tubes and submerge in water leaving
about 4 inches to the gauge out of water. Put in the freezer
freeze. Make a small brass coupling about 1 inch long. Cut
both tubes, tin the ends being careful not to get solder in
the ends of the tube. Solder the tubes into the coupling, use
a little flux on the tube ends. There should be enough solder
on the tube to make the joint. Make the coupling a snug fit
like normal copper pipe. Melt the ice and it should work like
new. G.M.
