waterpump/cambelt etc replacement howto?

Postby sandmonster » Mon Jan 04, 2016 1:23 pm

Is there a comprehensive howto for this on here - have had a little search but not come across it?

I'm gearing up to replace my thermostat housing (leaky t-piece) and will check/replace everything else that I can while I'm 'in there'. Could do with a comprehensive list of jobs/bits and any hints/tips that aren't likely to be in the Haynes book.

Also recommendations on the bits - I note MX5parts do a 'ultimate' kit http://www.mx5parts.co.uk/camshaft-timi ... -3328.html but it has a pattern waterpump?

Also my 1992 Eunos wont be 'early crank' in the options for that kit will it - how do I tell?

:text-thankyouyellow: in advance. :handgestures-thumbup:

The Short nose Crank has 4 "slots" in the pulley whereas the long nose crankshaft has 8 "slots".
I think there is only about a ÂŁ20 difference in water pumps between aftermarket and genuine so that's a choice for you.
I bought the kit from mx5 parts but asked for a genuine cam cover gasket as the pattern ones are not the same quality.

This looks like a place to start - seems to skip some bits, but fairly comprehensive... https://www.youtube.com/watch?v=YwaHeAPd14A

This one does the seals too: https://www.youtube.com/watch?v=gtZEUnnZYyI

Another one with some more bits: https://www.youtube.com/watch?v=2hLuUi32UgY

And this one lots of good tips - love the guy's hat - I think Wayne should have a similar one ;) - https://www.youtube.com/watch?v=oovptq0q7vc

Hi Wayne,

Not doing it for a few weeks - need some dry-ish weather forecast LOL :lol:

Just doing some background research and building up a list of stuff to order.

So far I have:

  1. Timing belt kit (Belt, tensioner, idler & spring)
  2. Water pump with gaskets
  3. Thermostat housing (got 2nd hand one - pipe is a little rusty, but do I buy new, or do the brass t-piece mod?)
  4. Thermostat housing gasket
  5. Thermostat with gasket
  6. Rocker cover gasket
  7. Antifreeze
  8. maybe cam seals
  9. maybe crank seal
  10. maybe hoses?
  11. CAS o-ring
  12. alternator belt - just changed
  13. power steering belt - just changed

So you can re-use the crank bolt, two 1" open spanners and a locking tool, and if needed torque wrench's.

Check Cam seals and crank seals, they to will need replacing.

Just about to do this too! Does the thermostat not need to come off then? Might as well not buy the housing O ring if not.
