Thread: ZF auto cooler lines

Discovery 1 have larger cooler lines from the box than my 89 rangie . Are these interchangeable and if so is it worth doing ?

Sounds like the difference between 22 and a 24 model . Line size may not mean anything much. look at the port restrictor size either end.Perhaps the percieved line size may add a little to the overall total system capacity , but if its got the same cooler then probably not much is to be gained or lost.
