hello all,

i am looking to replace the hoses on the oil cooler hoses and looking for aftermarket type hose.

the hose sizes are 11.5x18.5 and 11.5x18.5x38

what does the numbers stand for?

thanks in advance.

All I know is the first number is the diameter in millimeters.

11.5x18.5 is probably inner diameter and outer diameter

11.5x18.5x38 specifies the length, i suspect

When I did my tranny cooler install I used 3/8" line and it seems to be working so far. Not quite as tight of a slip fit but still snugs down hard.

FWIW.

1/2" hose fits the oil cooler fittings.
