Disconnecting Oil Line to Oil Cooler

[briankeithsmith]

Gang:

I am trying to disconnect the lines that connect my hard lines to my front oil cooler.

I've soaked them with liquid wrench, heated them with a propane torch, and had friend (who is much stronger than I) try to loosen them.

I can't get them loose.

What/How Now?

I really want to get this disconnected so I can run lines to my new front oil cooler.

If brute force does not work, then more brute force may be needed. I have heard of folks having to cut the nut before the oil lines will break loose, though this is typically back at the thermostat end input side.

USE KROIL THE OIL THAT KREEPS.

[Chuck Moreland]

I don't recommend heat. You are baking oil residue onto the inside of the tubes, and damaging the flex hose rubber.

Use PB blaster, it's a much better penetrant than liquid wrench.

As Jim says, you can also cut the nuts off. The hoses aren't that expensive to replace.

Kroil didn't work for me. I had to use the "wheel of death" as Dave Seeland calls it....the air powered cut-off wheel...to cut the nut....

Kroil is the best penetrating oil I have ever used, though.

Kind of trailer trash engineering....but I used a pair of vice grips....then put a pipe on each one. Obviously not on the arms that trigger the release....the other side....8^)

Then one person on one pipe, me on the other....snap. They cracked open.

I used a similar method to Mike but the other person was my foot. Not easy to break them apart and I ended up having new oil lines manufactured.

I got them off. I spent $85 and bought 2 huge S&K wrenches (they must weigh 8lbs each). Brought them home and popped the first one off in like 2 minutes. The other one took a while longer, but in less than 15 minutes I had them both off.

I guess it truly pays to have the right tools...

In case you didn't see the other thread I started, here is what I did once I got them broken loose...

If you use them once more in your lifetime, they are paid for.....

I used to large Crescent wrenches with pipes added on the end for leverage.

I cut mine with a dremel, just enough to put a screwdriver in the cut and twist to split the nut. Do not want to cut the threads on the inside.
