How to change your inline thermostats.
pudding:
Have a check around the plastic flanges that attach to the block under the chain cover, above the gearbox. There’s an O ring that likes to go hard and leak. The KO4 engines also suffer from a slight head gasket weep from the rear corner (pass side) of the head, which is what mines doing. Mine takes about 6-9 months to drop from max to min.

Guys does anyone know how much coolent it would need to fill back up the system? Also are there any bleed nipples to get the air locks out? Thanks

About 2 litres.

So I went to change mine today thinking it'd be a nice easy job. It was, there isn't one! Which is a bit of a bugger as it means I'm going to have to delve into the depths and change the main thermostat. :doh: if anyone needs a genuine inline thermostat drop me a pm £20 posted. By the way mines an 06 manual BWA.

Cheers for the info Pudding. Didn’t know I’d have to undo engine mount to remove alternator though... changing thermostat took 5 maybe 10 mins on my old mini!
max amplitude: VW call the inline ones “coolant regulator” or something very similar. They first told me only one but then when we looked I recognised the shape of the part under that name. But now it looks like I don’t have one anyway...
