Im trying to replaced my bad radiator and the bottom transmission line is seized in the fitting so everytime I try to turn the fitting to remove it from the radiator, the whole line wants to twist. I've PB blasted it and tried loosening and tightening. Is there anything else i can try?
two weekends ago when I did the engine swap from my 67 to my 66 pretty much everyline was frozen like you describe. I'd spray it with some PB blaster or your favorite penetrating oil let it sit. Then very very carefully and I cannot stress the carefully part. use a pair of vice grips to clamp the line part and use a line wrench to turn the nut. Watch the line to see if it continues to turn with the nut or if it breaks free. if you clamp it too hard you'll squash the line and if you twist too hard before it loosens you'll twist the line. I'd say use that as a last resort.
Use a propane torch to heat the tube nut a bit, not as far as red hot. Quench the nut with cold water, attempt to loosen the nut normally. Repeat if necessary and lubricate again when it's in the cold state. If you heat while the lubricant is still present, avoid breathing fumes. Devon
nothing worked... haha i ended up hacksawing the line clamping a hose to the cut line and then to a new line and fitting working as intended... at least for now haha.
You can run a barb fitting or just bend up some new hard line and put a bubble on it to work as a barb. I've done this on plenty of cars. Not factory correct, but it works great and makes it easier to do radiator repairs in the future.
Absolutely. Heat is your friend. Just try to heat the nut (the female threaded part) not the male part.
A hose and clamp over the cut line with no flare or other means to "stop" the hose from coming off will come off and make quite a mess when the tranny fluid sprays under hood ... ... ask me how I know
Something to try in the future is to hold the tube with the flaring tool yoke and try to turn the nut with a line wrench. Use lots of rust spray. Its saved my A&& many times.
A line popped off my transmission cooler (Hayden, in front of the radiator) in my '56 Chevy wagon on the freeway many moons ago. I put the clamp back on with a dime as a screwdriver and coasted slowly backwards about a mile on the freeway shoulder to the onramp, walked to a gas station, got 6 quarts of ATF (deep pan), refilled it, and was on my way. I rode that brake down the hill the whole way, at a ridiculously slow speed. Ended up with a crick in my neck from looking back. I'm willing to bet the underside of that wagon is still not rusted. ---------- Post added at 06:27 PM ---------- Previous post was at 06:26 PM ---------- Now that there is some pretty good advice!
I would of used a compression fitting and a replacement piece of steel line and a new nut. It would be a perfect repair
my Transmission line is not stuck it actually came off pretty easy. but my question.... I'm trying to figure out which lines will connect to the current a/t lines? my new radiator has the a/t holes on the right vice the bottom. I'm being told that i just need to flare the new lines and connect them to the radiator but the problem is... i dont know what size to buy. Could someone help me out so that I can start working on the brakes so that i can drive this car. Semper Fi, Gunny G maseusmc@gmail.com
Thanks for the help.. come to figure out.... I need a special tool to take the transmission line off... Where do I buy disconnect tool for a 1965 Buick Skylark V8 300 4.9l transmission cooler line? I bought a 4 back of tools from Auto ZOne but either they are the wrong size or I'm not doing something right. Please help.
