Plymouth Voyager trans cooler hoses leaking

The slick, wet puddles in my garage floor are driving me insane! I have traced the source to the transmission cooler hoses on my wife's '90 Grand Voyager (3.3l v6, 4-speed automatic). Where the hoses push onto the barbs on the in-radiator cooler are cracked and dripping. My question is, what kind of pressure rating will I need to look at on replacement hoses? There are no fittings crimped on either end of either hose; they're both held on with hose clamps. Would fuel hose rated for fuel injection applications work, or should I ask my parts house for something else? Thanks in advance - Chris

 

Welcome to the world of leaking trannys of the D/C minivans! Your solution will be good, on my 99 I have replaced my hoses a couple of times, known problem.

 

Thanks. Cabot. You say my solution will work; do you mean the fuel-injection-rated hose solution? I just don't want to burst a hose by working it past its rated pressure and wipe out the transmission. For having almost 200K miles on it, this van is running really good. I'd like to see just what kind of service life it will give me before it lays down for good!

 

don't use fuel line hose. go to your local parts supplier and ask for automatic trans cooler line hose...it may be sold in bulk so get yourself a rough measurement as you'll buy it by the foot and cut to length. use new clamps not the old pnes, they get all bent and distorted with age.
