Hello all, how long would an auxiliary radiator last on an 05 supercharged? I'd like to do some preventive maintenance by don't want to start throwing money at it. I've changed all the fluids, plugs and wires. It's got 150k miles on it. I am not the original owner by the way. Thank you all in advance.

On the S/C the auxiliary radiator is actually a supplementary engine oil cooler radiator connected to the oil cooler in parallel to the main coolant flow through the oil cooler. On the TDV8 the auxiliary radiator is just an extension of the engine coolant system. Sorry if you knew that already but it might be useful to know.

I would expect both to have the same life span as any other radiator with the correct engine coolant/antifreeze mix used. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
