Unplugging the g/p harness is certainly the easy/obvious route, maybe
a little too obvious though. I like the constant vacuum to the
shutoff idea; that can probably be done fairly easily in a manner that
won't be patently obvious to the uninitiated.

When the cooling system is pressurized with the engine cold, it's
almost always a result of exhaust gases leaking into the coolant from
either a bad head gasket or a cracked head. On 603 engine with the
-14- head, it's most often a cracked head.

Isn't there a terminal block in the bottom of the fuse box (under the fuse
mounting plate and the wiring harnesses) that feeds the GP relay? Much less
trivial... but equally effective. Less trivial and also effective would be to

slightly at a loss as to how I might go about temporarily disabling it

Joe, what do you mean by residual pressure? I'm curious if this could
possibly help with diagnosing water leak issues.

Don't fret too much Peter. I pulled the head from mine with a chain
winch suspended from a bit less than 8' ceiling in a too small garage.
