At least 1L (probably more) was added this way. The corrosion + inhibitors were unacceptably dilute as a result. Corrosion was surely + setting in in the coolant loop. + +Solution: +- Coolant loop flush :: I drained the loop and refilled with water. The drained + coolant contained substantial metal particles, is opaque and has the colour + of pale mud. I assume the concerns about corrosion were justified. The + engine was started and run at ~3000RPM until it reached operating temperature. + This ensures that the thermostat is open and that coolant is circulating + throughout the radiator as well as the engine. The engine was left to + cool and the loop drained once more. +- Coolant change :: New coolant was added. The loop has a capacity of ~5L. For + a dilution of 30%, suitable for temperatures of -20C, 1.5L of coolant + antifreeze was added to the loop and topped up with water. It would have + been better to at least partially dilute the coolant first. It's high + viscosity meant that it took a while to settle in the loop. + +** Notes + There are still some metal particles visible in the coolant expansion tank + (although much reduced from before). An additional flush would be sensible, + but I ran out of containers to contain the discarded coolant. It would perhaps + be sensible to perform the next flush and coolant change ahead of the regular + schedule. + + There is a 0.5L from the second 1L bottle of undiluted coolant left. This is + in the shed diluted to 50/50 antifreeze/water. If the coolant system needs + topping up, I should use that. + +* 2017-04-06 +** Issues + We don't know anything about the car's service history. It is sensible to + assume that all of the standard service intervals are due. +** Solution + I changed the air filter. I only bought a replacement for the intake air filter + but neglected the small filter for the PCV return. This is a small foam filter + sitting at the intake for the PCV hose. This is contaminated with motor oil + and needs to be replaced. Additionally I added a small screw to the intake + duct to the radiator grill. A small plastic protrusion is intended to keep + this duct attached to the air box, which was broken when we bought the car. + The screw takes it's place. + +
