[Biturbos4] Thermostat

[John Koenig]

For what it's worth, the factory procedure calls for 'sliding' the carrier
forward on special pins rather than removing it completely.  These are
easily made up from long bolts and lengths of pipe.  I've successfully done
a timing belt job this way, and it eliminates some of the disconnection
requirements.  Doing the thermostat will, of course, still require draining
the coolant.

I'd certainly echo the advice to use a new O-ring.

Short cuts rule!  Hope this helps.

John

Mike,

If you have ever removed the service carrier, then its just going a bit
further. If you have not, its a bit of a daunting task the first time
especially fighting with the front bumper.

Drain coolant  (already done anyway to remove service carrier), if possible
just move the carrier out five or six inches on the passenger side, if you
keep the drivers side closer than three inches out, you will not have to
unclip the six connectors  (possibly only the AC high pressure switch
connector). If you decide to do the timing belt at this time, its really
worth it to just remove everything in front.

Remove hard pipe from the intercooler to intake manifold, then the accessory
belt, and the passenger side timing belt covers, one has three bolts, one
has clips.

The thermostat housing has two bolts holding it....make sure you get a new
o-ring !! and make sure you use a torque wrench when tightening the two
bolts  (trust me, do not overtighten by more than 10 %)
