Great tips, thanks all!

Unfortunately, there have been so many run problems with this van (he's been
stranded twice) my son has no confidence in it, which is unfortunate, since
I encouraged him to buy it.  So, with these last two items I'll have
replaced almost everything:

Starter (Go Westy gear reduction)
Alternator
Alternator wiring to starter (Go Westy kit)
Grounds: Cleaned connections in engine compartment, replaced battery ground
strap and checked transmission ground strap
Fuel lines
Fuel pump & filter
Set throttle switch
Cleaned throttle body
Checked AFM resistance
Checked for vacuum leaks
Rebuilt injectors
Replaced idle control module
Capacitor fix in AFM
New tune-up parts and set timing
PO put in a GT rebuild AT, water pump, battery, and replaced the fuel tank
vent lines and grommets.

Only thing left after O2 and Temp 2 is the idle control valve, which checks
out as far as I can tell.

I'm hoping we can drive it around town for a few hundred miles and get he
gets his confidence back with "everything new".

Engine cold
Pinch hose or plug overflow vent on pressure cap. If air can't get in
coolant won't flow out.
Prep new sensor with O-ring.
Remove clip.
Quickly remove sensor, look for O-ring. Reach in and remove if stuck.
Insert new sensor with O-ring.
Insert clip.
Remove plug/cap.
Remove pressure cap. Top off coolant.
Replace cap and connect hose.

Done.
 You should only loose a quart or so this way.

Still chasing bugs in my son's '87, and I'm going to replace it and the O2
sensor.  It's got erratic high idle, stumbling when cold, and I think it's
running rich when warmed up.

Just wondering if there is a way to minimize coolant loss.

There are a lot of pipes into the T-stat housing, and I can't clamp them all
off.  And, does the O-ring tend to stay in the bore and need to be hooked
out, or will it come out with the old sender? I'm going to replace it.

I may just use this as an excuse to flush and replace the coolant if I'm
going to lose a lot anyway.

Thanks!

Stuart
