Coolant hoses

wiper

Member
Hi I'm new to this forum and would appreciate any advice
My z4 e85 2.0 is 20 years old now I just wondering should I change the coolant hoses
Has anyone done it and is it much of a job
Thanks
 
The hoses are fairly resilient

What tends to fail are the sealing o rings inside them

But usually only when disturbed

Your call if you want to replace them all, not the worst of jobs

However the main weak point is the plastic expansion tank. Do that first if it’s not been done yet
 
Hi Bigwinn thanks for your reply
I changed the expansion tank a few year's ago when it split
I'll probably leave the hoses for another while so
Thanks again
