Engine About To Break Transmission Coolings Lines Unless Someone Stops Me.

[DanB93]

Hello so I am about to replace my radiator and have run into trouble because of the transmission cooling lines. I don't want to break these lines but I have low hopes that I will because they are sooo rusted. I have hit them with that Buster spray and have gone out and bought a 1/2 flare wrench but thought I ask for some ideas. I ordered a new radiator and it came with a set of different connectors but I thought once I accidentally break then lines, these different connectors may come in handy to connect to hose in between the repair. I was even thinking of just cutting these at some point instead of breaking them. Is there a lot on pressure running through these? Also are they full of trans. fluid in there or does ti pump out when engine running? I am open and hoping for suggestions. Thanks

put a torch on it and get it hot, then let it cool. repeat that cycle 5 times, spraying oil inbetween sessions. then get it nice and hot and try breaking it. its probably going to break though. might not. definitely need a nice flare wrench. There isnt too much pressure on those lines. yes it is filled with transmission fluid. be careful not to light anything on fire. I would try a hose splice if I needed to, just make sure to splice with plenty of hose and double clamp each end.

Not to be silly, but you realize there are 2 fittings on each line. You put the larger wrench on the fitting going into the radiator and then the line wrench with a cheater wrench for leverage on that fitting to the line, Sometimes it helps to have a friend hold the wrench to the larger fitting.

Spray down the fittings real well with pb blaster and let it sit in for a while. You may need to ut some heat to the fitings to help crack them.

Those actually don't look too bad. You can still get a wrench on them. You'd need to use two wrenches here

If you decide to remove them with a hammer after a few failed attempts can you at the very least video tape it? Never know, you could be the next YouTube sensation?!?

Kidding aside, they don't look that bad and as mentioned above, two wrenches and a little bit of gusto and you should be good to go. You will however need to ditch the male flare fittings on the new radiator for some inverted flare fittings if you want to keep the stock connections as they currently are.

If you use some tranny rated hose clamped over the hard lines, flare the ends of the hard line enough that the hose and clamp can not slide off under pressure.

Whoops. Sorry about that.

Well Thanks for the replies again. Between hitting it with that blaster stuff and a flare wrench they actually came off ok. I was really surprised. The rest of the install went by quickly. I guess if I ever get around to covert to a 5 speed i can ignore these in the future.
