Re: Oil Cooler Line
Technically you should hold A so the hose doesn’t twist and the flare isn’t scored. According to Parker most leaks are caused by improper tightening of the fittings. The flares should be drawn together with no turning or twisting as it’s drawn up which would cause scores on the mating flares.

Re: Oil Cooler Line
OK, I can buy that. If you hold A and turn B (Can't turn C) you indeed will keep the hose from twisting.
But the flare WILL be moving against its seat (A and B will be rotating in relation to each other, don't see any other way to do it as you certainly aren't turning C) ...... So I'm not understanding the "flare isn't scored" part....1978 53' Motor Yacht "LADY KAY V"

Re: Oil Cooler Line
A is the male fitting, B is the female. They need to be unthreaded from each other. B should turn freely at the joint with C. C may need to be held to get the rotation from the hose. Paint and rust can lock that joint up.

Re: Oil Cooler Line
That big stuff can take more than enough torque to un-score itself. Never had one fail over decades of farm, hvy equipment or boat hose changes.

Re: Oil Cooler Line
Paint might be what holds it, Add to the Hold A, loosen B, you might have to hold C if it wants to turn. Think old GM fuel filters at the carb, more often then not the filter turns 1st, twisting a steel line. Like others said once broken loose should be able to finish by hand.
