Bolt size?

[oddnumber]

Morning chaps, would anyone happen to know what size bolt holds the lower half of the thermostat housing onto the upper half on an early cooling system? Also the bolts that hold the housing onto the water pump?

Thanks for any help

Item 12 - M6 x 20mm
Item 15 - M8 x 85mm
Item 19 - M6 x 55mm
Item 20 - M6 x 30mm

Cheers, Ian.

Ian, you're a star - thanks very much.

I'm guessing that to change the thermostat it's just the two M6s to remove the lower housing? Haynes is a bit sketchy on the subject

You'd think so wouldn't you ? Sorry I'm a late-system kinda guy myself

After what I've read and learned, I'm beginning to wish I was now.

Note which way the thermostat is.. upside down

Cheers Kev, I'll bear that in mind. I think the old one is sticking open as the van is taking forever to warm up and using loads of fuel - would it be possible that the existing one is fitted wrong?

I don't think so

oh well, worth a thought

It must be sticking a bit then.

As a consolation I haven't heard many people say they have had problems removing the lower part of the thermostat housing . It's usually where the housing bolts to the pump, or where the pipe coupling fits (part 10) that causes the problem for those that wade in there.

Say it's so!

A bit of luck would be just the job.
