I got me a '63 cj5 i just got and i wanna flush the radiator but i need to empty it first. I was wondering if i had to just let it leak out of where the hose hooks into the block or if there was a wing nut or something i can loosing up on the bottom of the radiator to drain it. Any ideas??? :-O :-D :-O :-D :-O [addsig]

there should be a drain at the bottom left that you can drain it at, make sure you have something to catch it in, and dispose of it properly[addsig]

Thanks bro, i look under there and find it and drain it. Its running a little hot so i hope it helps somewhat. Its the stock radiator so it might be time just to buy a new one but im gonna try this first. Thanks again. :-O :-D :-O :-D :-O [addsig]

Far Right is correct it is on the under side of the radiator,
there should be a wing nut...Don't give the coolant to cats
they don't like it....J/K :-O [addsig]

Hey, what do you reccommend for a new radiator. Is there any way you can put a 4 core in there instead of the regular 2 core radiators i've seen for sale for jeeps??? :-O :-D :-O :-D :-O [addsig]

A 4 core might not fit in the space, you need to measure from the fan to your stock 2 core. If you have a lot of room between the radiator and fan, say over 3" then a new 4 core may fit.
Does your CJ-5 still have it's fan shroud? The shroud is important cuz if forces the fan to pull cool air from in front of the grill, not from in the engin compartment, (warmed air)
If all the components of the cooling system are working properly,then, you'd have no cooling problems, but, as you mentioned, it's heating up. So, something's not right. I suspect you already know this huh? Duh.......
Have you tried running with out the thermostat? perhaps is stuck closed. Another item, (not sure if your year had one ) is a fan clutch. 63' may not have one, but if it does, is it operating porperly? to check it, while it's cold it should be somewhat hard to turn with motor off. As it's warmed up, (from hot air from radiator) it'l start to grab alittle more until it's cooled off by the air flow from radiator. As radiator heats up again, the warm ari then heats up the clutch and caouses it to grab, causing the fan to spin up and move (pull) more air thru radiator. This process is continually on going while the motor is running.
If the fan shroud is missing, then the fan can't pull fresh cool air thru the radiator (cooling it). Course, if the radiator is junk, well then, all of what I just typed won't work anyway! [addsig]

Ummm . . . Yea, i got the fan and its still got the shroud right on the radiator. There isnt much space between it and the radiator, i'd say an inch or two. IS there anyway you can move the radiator further up in the grill that way a 4 core would fit so it would be cooled better? Im currently flushing out the radiator and it seems to be in rather good shape so im not sure what the cooling problem is from. :-? :-? :-? [addsig]
