Great write-up, thanks very much.
I'm looking at this DIY for preventative reasons. My coolant is original so I think needs changing soon and I've read that thermostats are worth replacing at this sort of age too (I think it's working fine but for a few£££ worth a change). I think the A/C, power steering belt and the alternator, water pump belts could probably do with a refresh for age reasons too.
Does my reasoning seem ok?
Has anyone got experience of the lifetimes of water pumps or tensioners (I'm trying not to waste money)?
My M3 is Nov 2012, 38k miles
Thanks |
My '08 has 66,xxx miles.
I'm still on the original water pump and thermostat.
Both belt tensioners are also the originals, but I did have to replace the pulley wheels themselves at around 55,xxx miles.
When I saw the price of the complete tensioner assembly that BMW wants you to purchase, I decided that I'd try and find the wheels themselves. That saved some significant money.
