Radiator

Ahhh!! I'm so pissed right now.

My new radiator arrived today. I had everything I needed to swap it in for the old one. Until... The farking transmission cooling lines would not unscrew from the old radiator.

I really don't want to take it to the shop for this problem, but I may not have a choice.

There are two choices listed in the Ames catalog and I have no idea which to order if I go ahead and just cut the old ones off. I dunno...

This was supposed to be an easy project... half an hour to an hour tops. Now... I'm just... grrrrr

EDIT:: I have a Turbo 400 transmission in it now.

I've had this happen a lot of times. The flared end of the tube becomes one with the connector. The solution is to use a tubing cutter and cut the lines. You can then: get new lines, or: flare the old lines with new fittings attached,(if the lines are long enough), or: install barbed brass male fittings in the radiator and splice the lines in with a short length of rubber trans line and clamps. Any of these methods will work...the rubber hose splice is the easiest, and is a reliable fix.

My anal-ness would force me to get new lines where as any above suggestion is cheaper and will bet you back on the road sooner...!

I would try heating up the nut that screws into the rad and tap it and try to loosen it with a line wrench......JB.

I have good news! The Liquid Wrench did it's thing and the lines came undone rather easily.

I still may need to get new lines though as I now have very minor fluid leaking from both connections into the radiator. It's like a drop every 5 minutes or so. I'm going to continue to drive it for now, though I will make sure to check my levels frequently.

Also, when I put fluid back into the transmission after the filter change, I did put in a bottle of Lucas Transmission Stop Leak. I'll see if that works it's magic and seals these up as well.

Lastly, I'm thinking about taking it to a local show tomorrow just for ****s and giggles.

EDIT:: Thank you all for your suggestions. I do appreciate the time you take to help out a stranger.

hey wonderin if someone could help with my overheating problem with my 66 gto? It has a fairly new radiator and i changed the thermostat and flushed it and added all new coolant. The next time i took it out it overheated after idling for about 12 minutes on a cool day about 66 degrees. Is it the fan clutch?

Update:: I ordered new upper and lower hoses as well as new transmission cooling lines. I checked the current hoses and they seem to be ok, but I just want new ones on the new radiator.

Wayne... Are you sure the new thermostat is working properly? Also, what motor do you have? Sometimes the lower hose can be sucked shut if it's worn out. That will restrict coolant flow as well.

Don't forget to put the spring back in the lower hose so it don't collapse.....JB.

I ordered a new one of those too. It was only $5 so I figured why not.
