Waterpump Bolts size/thread

[Gregmorse]

Good afternoon all!

I've had a slow coolant leak for a while, I always put it down to air in the system as everytime I attemped to bleed the front, more air would come out.

There was never any puddles or drops under the car.

Long story short - This week I came to notice a few drips off the right hand side of the engine block. Managed to trace this back to around the waterpump which likely needs replacing as lots of red juice all over the place! Think it's been leaking from there for a long time but I check the level almost everyday/every couple to make sure it doesnt go low.

Anyway - Once I'd located the source of the leak - I noticed an entire bolt holding my waterpump in is missing!!(I've owned the car 4 years and never touched it, so it's been missing the entire time)

It's the one thats very close to another bolt (there's 5-6 that hold it in place, 2 of which are almost touching the rest are more spread out)

Does any one have any idea what size/thread this bolt is?

It's M6 x 1.5 but you'll need to put something in the hole to measure the depth, some of the bolts are longer than others.
