4.8is Coolant Tube & Valley Pan Parts List

While changing the oil last night I noticed a few drops of blue coolant hanging off the back of my under ride. I know I had a slow coolant leak as I have been trying to locate the leak for a few months only needing to add 3 oz. or so of coolant every 2 months or so.Hoping the leak stays small and I can postpone this service until Spring.

But now that I know the general vicinity of my coolant leak I am going to begin acquiring the parts/pieces to replace the valley pan & gasket and coolant transfer pipe seals as well as the large coolant pipe, and anything else that is going to be apart while in there, just in case it decides to leak massive amounts before my scheduled downtime.

I'm going to go the AGA coolant pipe route and replace all cooling system components but plan to replace PCV related items, too.

Going to start a list but wondered if anyone else had an inventory of what you may have replaced when you did this job just to make sure I don't miss something.

I'll post my list later once I gather the part numbers I think I'll need.

Nothing to add as you are approaching the project with open eyes and doing it right...

On secondary thoughts
Add in cam position sensors (CPS) seals as you will be right next to them as you work

Thanks for that StephenVA. Just added those to the list.


I've already got valve cover gaskets and spark plugs from an earlier planned intervention. I'll be doing those as well.

Been a slow start on this project as I have been putting it off until I can drive my E38 while I work on my 4.8. Now that the salt is off the roads I just ordered the coolant pipe from AGA today. Going to fill my fcp shopping cart next!

Anyone have any input regarding quality and fitment of parts in certain locations? I know when working on the family of e46s I had to maintain in the past that Rein was not recommended for the mounting plate on the radiator.

Was thinking about going with BMW OEM there. Any thoughts on fitment in other areas between BMW (OEM), Rein or Vaico?
