98 JGC radiator question

Neoisthe1 did pass the time by typing:

Should be. On my 4.0 it is located at the bottom passenger side of the radiator. You fit a hose to the outlet then unscrew till it starts draining.

Some do, I don't bother since most of the block will drain.

I had a hard time finding it the first time I changed the fluid on my old Cherokee. Once you find it, it'll be the only thing you see down there from that moment on :) n.

Neoisthe1 proclaimed:

Which engine? V8 or 6?

On the 6, the radiator should have a draincock on the lower right. On the V8, on the lower left. Drain first with radiator cap on, then remove cap to continue. Then drain the block if desired...it can hold quite a bit of coolant.

Thanks everyone for responding, I finally found it with your help - if it was a snake it would have bitten me - LOL.

Next novice question - while I am under there I might as well do a lube job - any advice on fittings,type of lube to use, etc. I assume the ball joints, steering, any other places ?

Again thanks for all your advice, Morph

Thanks for the tip Harry, I never heard of using PH , but this makes sense. I know you can also use a multimeter to check for electrolysis. 300mv and below is OK. Ground the black lead to the (-) battery terminal and put the read lead in the coolant. Take a reading with the car off, if it is above 300mv - time for a flush and new coolant. If it is below 300mv then start the car and let it warm up. If the reading goes over 300mv, time to flush change the coolant.
