I Love the way the water pump bolts shear on removal

[megaflea]

as subject,

water-pump was leaking so decided to replace the gaskets quick £6 fix,
turns out nearly all the bolts sheared on removal, quick fix my ass now i gotta replace the whole unit damnit!

This is a pain in the rear.

Quite why they used such fine threads in alloy is beyond me, i usually run a tap through the cylinder head and a die over the bolts, or even better replacement bolts.

Only it sounds like you didn't even get as far as removing them in one piece.  

[megaflea]

the bolts are wrecked and i wouldn't dream of re using the remaining bolts, im just glad they sheared at the head and left something sticking out in the block for me to grip hold of to remove the remaining snapped bolt,

Renault can supply replacement they are about £2 + vat a bolt but id rather try and get something a little stronger, but yeah the threads are shocking, the they bolts made of cottage cheese?

on another note im not trying to source a complete replacement pump as a selection of bolts sheared off in the housing to its trash now, im hoping Mike who run the Renault 5 gt spare site can sort me out,

im after a whole bunch of stuff, unfortunately little rex is now off the road with 363 days of MOT haha damnit  i'll pm him


damn renaults

so now i just need to get some bolts any idea what the thread size is?
im guessing something like

7/32 unc x 2"
7/32 unc X 1.5"?

anyone know?

m6 1.00, ive got the lengths written down somewhere

the only imperial stuff is oil related, otherwise entire car is metric

Hey fishead,
Are you sure its a metric thread for the water pump to head bolts?, they are quite a fine thread,
id really appreciated the lengths so i can go and get some hardened ones,

as i take bits of the car apart i have noticed there is a selection of metric nuts bolts and treads, but damn them torx fitment bolts, i can take my other card (rs1800 fiesta) apart with just a 10 and 13mm spanner haha

but yeah Renault sell these nuts for a couple of quid each which is a little excessive  (i know main dealers generally are but generally nuts and bolts are usually priced reasonably)

[owe]

there deffo m6, u dont really need hardened ones tho, just put a bit of cooper grease on them before fitting. an like ash said run a tap into the threads on the head
