Hi All, I've been having a problem with my 2007 Rav4 2.2 D4-D (no dcat) for about 6 months now, where on long journeys I lose coolant. I'll lose nothing on my day-to-day commute to work (10 miles, 30 minutes each way). However if I don't check it for a couple of weeks I'll find that I've lost a small amount. On longer journeys I can lose a lot. i.e. a 100 mile trip a couple of months ago I lost about half the tank each way, and over 440 miles this weekend I put almost 1.5 litres into the tank
