Re: Radiator / Engine flush
I've used Wynns radiator flush and found it loosened quite a lot of crud the garden hose didn't touch. But I'm sure there are others that will perform as well. Until recently, I didnt think it would make a difference, but it did. This was on an Audi though and not a SyTy. The heater stopped working and at first I thought it was a heater valve somewhere that was frozen. I left it a while, until I got around to it, only to find it didn't have a valve, only air diverter flaps. Same principles apply though. Next time I do a flush, I will be using the same product again, just means doing a double flush. I never stop learning in this game.
