MOT Starts With A Bang

[Tim330]

Took the car (e46 330i) for its MOT this afternoon. During the emissions test whilst keeping up the revs the expansion bottle for the coolant system exploded. Turns out the fan wasn't working so it overheated quickly whilst sat still. Luckily the garage managed to get the replacement parts today. It made everyone jump but fortunately no one was in the engine bay at the time so escaped the steam. Awaits cool story bro

More of a hot steamy story than a cool story I would think?

Better watch out that your gasket isn't blown...

[Tim330]

Will find out tomorrow... Hopefully the pressure all went out the bottle when it blew.

It's not the pressure that causes the issue, it's the heat.

We turned it off straight away after it went, hopefully caught it in time. Its starting to get expensive keeping this car going, on 101k miles now. Late last year it had new clutch & flywheel then in January a new drive shaft!

Got the car back after 4 days driving a 1.2 Corsa courtesy car which wasn't fun on my 30 mile motorway commute. All seems well with no coolant loss. The fan needed to be replaced.

New coolant tank £40
Fan £185
labour £90
