I have a 2014 RRS HSE Supercharged v6 with 118K miles and the coolant pipes appear to have been upgraded to the aluminum pipes prior to my purchase of the vehicle. There does seem to be a very slight coolant leak as I need to add just a bit of coolant every few weeks, and the coolant doesn't pull back into the reservoir after the engine has cooled down. The engine runs good, does not overheat, and there are no check engine lights on. I suspect it may be the O-ring seals where the pipes bolt into the engine valley underneath the supercharger may need to be replaced as I see some slight signs of what appears to be residue with my scope. Am curious if anyone else has experienced or observed a similar situation? Also, if I end up having to remove the supercharger should I also replace the oil cooler while I'm into the engine that far? Also, if an oil cooler replacement is recommended, any particular brand or OEM? I noted the OEM version which appears to be made in France is around $650 from FCP Euro and there are other aftermarket parts that range from $85 to $350 and most appear to be mfgd. in China. Thoughts welcomed and appreciated.
