18 - Oil leak :: puncture in oil filter
19 - Coolant leak :: leak at the thermostat gasket
22 - Oil change :: This was due anyway
23 - Sealant added to coolant loop
27 - Diluted Coolant :: We only topped up the coolant loop with water in response
28 to the leak. At least 1L (probably more) was added this way. The corrosion
29 inhibitors were unacceptably dilute as a result. Corrosion was surely
30 setting in in the coolant loop.
33 - Coolant loop flush :: I drained the loop and refilled with water. The drained
34 coolant contained substantial metal particles, is opaque and has the colour
35 of pale mud. I assume the concerns about corrosion were justified. The
36 engine was started and run at ~3000RPM until it reached operating temperature.
37 This ensures that the thermostat is open and that coolant is circulating
38 throughout the radiator as well as the engine. The engine was left to
39 cool and the loop drained once more.
40 - Coolant change :: New coolant was added. The loop has a capacity of ~5L. For
41 a dilution of 30%, suitable for temperatures of -20C, 1.5L of coolant
42 antifreeze was added to the loop and topped up with water. It would have
43 been better to at least partially dilute the coolant first. It's high
44 viscosity meant that it took a while to settle in the loop.
47 There are still some metal particles visible in the coolant expansion tank
48 (although much reduced from before). An additional flush would be sensible,
49 but I ran out of containers to contain the discarded coolant. It would perhaps
50 be sensible to perform the next flush and coolant change ahead of the regular
53 There is a 0.5L from the second 1L bottle of undiluted coolant left. This is
54 in the shed diluted to 50/50 antifreeze/water. If the coolant system needs
55 topping up, I should use that.
59 We don't know anything about the car's service history. It is sensible to
60 assume that all of the standard service intervals are due.
62 I changed the air filter. I only bought a replacement for the intake air filter
63 but neglected the small filter for the PCV return. This is a small foam filter
64 sitting at the intake for the PCV hose. This is contaminated with motor oil
65 and needs to be replaced. Additionally I added a small screw to the intake
66 duct to the radiator grill. A small plastic protrusion is intended to keep
67 this duct attached to the air box, which was broken when we bought the car.
68 The screw takes it's place.
