Mine is not overheating. That era passed after changing the HG. I don't pull caravans.
My VC fan is from 300TDI which is a direct fit bought new , genuine about 2 years back.
The radiator is the one came from the factory yet it's fine.
I just want to get rid of the habit of eyeing the temp gauge & the feeling that the needle will go to red the next moment.
In addition to what datatec pointed about the radiator, I noted that the VC fan is not centered on the radiator (on a vertical axis).
It's more towards the RHS. Should not it be more towards the LHS where hot coolant flowing in.?
Leave the bloody thing alone. If it ain't broke don't fix it. With your track record you will cock something up. What was the end game with the chains and injection pump you never did say?
