the top left hand hole has no thread in it,do you think id have to tap it or do you think ill get away with the other bolts holding it in without leaking.

 

I'd thread it personally

 

id thread just to be on the safe side

 

any idea what size tap to use?i think its suppose to be a m8 bolt that should have been in there,if i tap it with say a m9 bolt wont i have open up the hole in the water pump also.

 

scotty did your plugs turn up today?

 

no mate emailed matt lewis said they were sent monday and should of been here 1-2 days so there defo late im a bit p***sd off like

 

As said defo needs tapping, you most likely will have to open the hole up a bit in the pump but lots of meat to do so, some one was seriously over tightening to strip a thread there!!

helicoil???

 

to be honest tabs the hole is smooth inside,my first thought was that maybe a dowel went in there,but i cant remember taken one out when i removed the pump.possibly someone in the past has had a go at drilling the threads out and not completed the job.
tabs what size tap would you use to re-thread the hole.

 

had no experience with helicoils but will look into it.

 

just to update,had another look at my water pump today as i was painting it,if you look at the picture you'll see that there is a hole in the block but no provision in the pump to put a bolt through,has anyone got there water pump off at the minute to have a check to see if this hole is supposed to be threaded or is there different pumps that actually use this hole.

 

lol I was just thinking that I didnt recall that hole being threaded/in-use as I looked at the first pics

 

I'll try to remember to look at my pump tomorrow for you.

no need for a bolt there mate rebuilding mine and is the same mate

 

so whats it there for?if you look at the back of the pump water flows from the pump into that hole.
