Bleeding cooling system

[mr_cool]

I change my coolant today on the leon as it was looking a bit sorry for itself and with winter coming cant go wrong.

It only took about 3L where I thought it was about 5l, maybe some stayed trapped in the system? Anyway am I correct in saying that the system is self bleeding? Elsawin says run the engine until the fan comes on and top up if required. No mention of taking hoses off or a bleed screw.

I let it idle for about 10mins and the fan never came on but the temp sat nicley at 90. I took it for a short drive and I was now getting hot air out the blower, I check again and the coolant took another 500ml to bring it back up to level.

Do I need to bleed it in any way or should I just keep an eye on the level for a while.

Cheers

I'd keep an eye on the level
ELSAWIN should be 100% correct

cheers, what about it taking 2L short than the capacity?

I didnt run it until the fan came on like elsawin said but a good 10mins idle and stayed at 90 when should the fan come on?

mine is about 91-92

dunno about the missing 2L, how much did you drain out?

You'll always have some in the system i can't see how you would drain every last ml tbh.

I drained my radiator today, was going to drain engine coolant side aswell but the sandwich plate hose was proving to be a PITA and gave up.
Where did you drain your coolant from?
I got 2 Litres from the radiator, which was replaced 2-3 dolution of the OEM coolant.

so if you didn't drain the engine I can see why you only got 3 instead of 5 litres.

I just drained from the tap at the bottom of the radiator

Aye thats just the rad fluid, theres still fluid in the engine cooling jacket
