My '09 2.0HDi X7 is losing water! I thought I'd been getting a whiff of that 'radiator water' smell over the last couple of weeks, but despite having a good look under the bonnet, I couldn't see anything obvious. I did a 150-mile round trip yesterday, no warning lights (is there a low coolant one?), engine temp gauge normal, heater working normally. Then, yesterday morning, I spotted a wet patch under the front offside corner as the car was parked outside my mum's - I thought it was aircon drain-off. Then I realised I'd not had the aircon on!
I looked under the bonnet - top hose stone cold, despite the temp gauge showing 4/5 bars (so not stinking hot as I'd not gone far), radiator stone cold, heater working fine. New thermostat was fitted a couple of months ago - what a pig of a job that was!
I've just been looking under the bonnet again this morning, engine stone cold. The level in the header tank looks normal - I expected the level to have dropped and a top-up being needed! I let it tick over for a minute or so, revved it, no change in the header tank level. I'm confused, to put it mildly!
Regarding coolant, pink Total 'Glacelf Auto Supra' seems to be the right stuff, although I can get Comma Xstream G30 for not far off half the price - any thoughts?
