New Radiator Warning: leaking plug

The new radiator has a place to connect a hose under the radiator cap on the pressure side. This was capped off with what looks like a vacuum cap. It was a very thin rubber plug and only lasted about 800 miles before total failure. You are going to need to upgrade this cap with a better plug.

Plan A … was to use about 6 inches of 3/8 fuel line and a longer 3/8 bolt with 2 hose clamps on the shank portion of the bolt. Bend the hose down 90 degrees and secure it to the transmission cooling line.

Plan B … was to use a short bolt threaded into a small piece of fuel line and just clamp it.

I ended up going with Plan B as I tend to over think things. I did cover the bolt threads with silicon first and let it dry. The parts to do this came from a in-line fuel filter, as they come with 2 short hoses and 4 clamps.

Here are a few pictures of the fix I did.


The first photo is how I got the new radiator.

Turns out it said Murray on the box and was the same thing O'Reillys sell for $60 cheaper.

Ok, thanks. I'll watch out for that extra fitting - and not buy one with it.
