Well.....last weekend, I found my "last" coolant leak.
There is a plug on the bottom of the radiator (brand new radiator).
I'm guessing some universal hole for a fan switch that is plugged with a allen head for those who don't need it (i.e., me).
It only seeps out when its at running temp and stops. The allen head is very large (9/16" allen....hard to find in two towns I looked)
But I got it under control with a custom piece.
I did not want to put an additive in there (Bars or whatever)
So I used some pipe dope......but no dice.
The allen plug that I took out didn't have the best looking threads. It had nicks in 8-10 spots (all the high spots but still threads fine)
I am guessing that is why it leaked. Threads on the radiator looked good.
Who ever makes the radiator for the company (middle man i bought from) put some type of pipe dope on it before....I could see it and had the pleasure of scraping it off.
These pictures are before I thoroughly cleaned them......or at least I gave it my best.
The company told me others used JB Weld and told me to do the same thing. So I did.
The plug is not aluminum and is cheap metal.....the threads just suck....period. "Others" means its ain't the first time.
But what do you want for a radiator/fan/silcone hoses/clamps that cost half the price of a nice Walker radiator for a hot rod??
Should be done curing in 14 hours lol.
