Thread: Replacing 300TDi oil cooler hoses - any tips/tricks?

O rings didn't seem to be a problem - they slide on the fitting

A good set of flare nut spanners is good to have (although not absolutely necessary) - from memory the flare nuts may be different sizes on each hose.

On my defender I found the cooler hoses leaking where they were crimped.
I just ground and cut away the the crimp and the old hose.
From any hydraulic hose supplier youn can buy 1/2 ID oil resistant hose cheaply by the mtr... ( It looks like normal heater hose.)
Slide the new hose over the old pipe stubs and secure with normal hose clamps.......never had a problem since.

... that's where they usually go


... some people braze barbs on to make sure, but it's not a high pressure environment so hose clamps might do

count the number of old O rings you have after you pull the old pipes out.

Dont put the new ones on till you can account for all 4

It does cause a mess when you only find three.

Cheers Arthur

of course the best tip is...

pay someone else to do it...

I'm not doing much this weekend.

Thanks guys...

I won't get to it this weekend, so it will have to wait until next weekend.

While I am at it, I will replace the gasket behind the oil filter head as it is a bit hard to see where the leak is actually coming from.

Cheers
