Installing water pp cover and thermostat... hints/tips

New mechanical seal installed. 79A1.

Both water pp housing and t-stat housing on the bench.

Is there a preferred order of installation (to facilitate ease?)

Can they be installed as an assembly?

 

8 months later, sigh, ready to hit it again. Good thing I took lots o' pics. Reviewed previous work while at breakfast.. Now to go home and get something done..New O-Ring from  www.z1300.de
Fits water pump shaft.

Cleaned both surfaces with lacquer thinner and clean rag.
Lightly coated with Lubriplate 'cream' for initial start-up.

Impeller installed. New circlip too. Used a wedge to keep impeller 'seated enabling access to circlip groove.

Triple checked circlip seating as correct.

.
 

Thermostat tested prior to install.
Crude, but good enough.Starts to open ~185, full open at ~195F.

Cleaned up gasket surfaces.

Thermostat first, then pump cover. Vice-Versa? As an assembly?
This isn't final assembly.. just a mock up.

Mine just sprung a leak yesterday, but only for a short time upon cold startup, then nothing the rest of the day, which tells me thermostat related.  I hope that I don't have to go through that.

No replies in 21 hours- No surprise. I thought I would leave it alone and let someone else weigh in. I guess not.
Lubriplate on the seal face? No, no, no. The rule of thumb is to lubricate moving parts in a component with either the lubricant that lubricates the moving item when the machine is running  which in this case is the coolant in the system. Static o rings can be lubricated with o ring lube for installation and it's a must. If you don't lubricate the o ring, as it's installed, it deforms and it needs the lubrication to allow the o ring to naturalize in the groove after being squeezed in to position.

Thermostat and housing first since you need the room to install the thermostat, gasket , spring and housing and hold in position while you install the 2 screws.


water pump to follow and ensure that you install the tube in the housing and leave the circlip loose up the tube until after the housing is tightened down, then slip the tube up into the thermostat housing and install the circlip.

(and all of this is detailed in the FSM page 62, 63 including the requirement to lubricate the seal face with coolant)
