Had a conversation with someone who works extensively on the V8s. his view is whether you use plastic or aluminum pipes you shld replace them every 5 years on the v8 and his view is the aluminum don't offer any real benefit.

thoughts?

 

Replace the aluminum tubing every 5 years?!? Thats my thought.
What is important is sticking to the fluid change schedule.

 

@ttforcefed simple answer no, @guy had it right.

Instead change your coolant every 2 to 3 years like you are supposed to. And don't use the cheapest coolant you can get, and avoid coolant flushes they are not nice to plastic bits or heater cores.

 

any view re: plastic vs aluminum?

 

I would go aluminum LR has specified that for the SCV6 as a replacement for the plastic, so not reason not to on the V8.

 

If you can even find a good aluminum crossover for the 5.0L V8

 

Oh, I thought they were available for the 5.0... of course, from the factory that would be fantastic as the 5.0 is at a minimum 12 years old?? Very few would continue parts improvements over 12 years. And those that do, need to charge dearly for the privilege.

 

there is a kit now for the 5.0 that has an aluminum rear crossover, but for some reason the front is still plastic. i can't find an aluminum front crossover for the 5.0 anywhere.

 

Lucky8 sells a kit, but out of stock. Had one ordered but never came. Backorder issues. Had to cancel and am putting LR OEM in tomorrow.

Oh well, the originals lasted over 190k
