stop the anti-freeze bath

Does anyone else have to reach up and around to open the radiator drain? no way to do this without soaking the arm with anti freeze.

maybe it is just the grand cherokee limited 5.2, but I had enough...thats all I can stand !
I will replace the draincock with an extender or other type... he thought.
NO you wont, said gmc.

the threads on this are -- according to the local pro -- "acme" threads, not metric and not english, therefor there is NO off the shelf replacement, other than back to the same thing you already have.

I can verify that there is NO off the shelf fitting for this, auto stores/ home centers/ specialty shops/

I took a nylon threaded to barbed conector, found a nut with 'close to the thread count' as the "acme" and forced the nylon into the nut -- effectively cross-threading, remove and force into the radiator - effectively cross-threading tight.

add a length of plumbing hose (good to 75 psi - far more than will be seen from the radiator) and a 1/4 turn ball-stop spigot. clamp both ends for good measure.

Test drive to full op temps, verify connections,
goodby to soaking arms in antifreeze.

lol nice! Just be sure that hose and plastic part can withstand hot temperatures without deforming.

Pro-tip:

If you leave the radiator cap on and pull the drain plug first, very little coolant will come out. Then pull remove the radiator cap to quickly finish draining the system.

1. the new fitting is the same material as the original plug, should be good.
2. apparently a 5.9 has more room under the hood, the 5.2 has no space for an arm, even a thin one. the petcock is located under the steering box behind the fan shroud, access ONLY from under - and reaching around the stabilizer bar. (believe it, I would not go to this trouble if I could reach it from top side.)
3. 'rrigghtt' only a little soaked (been there, tried that), the 2nd problem is the anti-freeze puddles in the lower fan shroud and other places, the local animals will find and drink this poison.
4. the real question is why GMC didnt make a standard thread there! so a standard extension could be used. "its a jeep thing" eh.

I guess you will just have to get a 5.9. Only way to fix that problem.
