[QUOTE="Mustang Guy, post: 128081, member: 13485"] After you get the radiator hot tanked and engine flushed, do as [USER=21648]UnexpectedBill[/USER] suggests and inspect the coolant pump impeller for cavitation pitting and electrolysis corrosion. And after you have thoroughly scraped and cleaned out the heater, install an AWG 10 bonding (ground) wire from it to the engine block. In essence, you have a dissimilar metal "battery" here with the transient current being carried in the coolant (this is also why there is usually a separate ground wire on an aluminum alternator). For a flushing agent I recommend an oxalic acid solution or CRC Evapo-rust (remove the thermostat for flush and rinse). For coolant I recommend (and use it in all my equipment) Final Charge 50/50 premix. [/QUOTE]
