NEED HELP changing thermostat! 850 95

posted by  someone claiming to be dave on  Thu Dec 7 08:11 CST 2000 [RELATED]

HELP!

I've drained my coolant 1/2 gallon, pulled the upper radiator and expansion

tank hoses from the t-stat housing, but the 2 large torx screws that hold

the t-stat housing to its base are extremely reluctant to budge.

Is it common for these suckers to require an ungodly amount of torque in

order to break them free, or should I leave this potentially destructive

operation to a professional?

My torx bit is a 1/4" hex, not especially high quality but in excellent

condition. I have a Craftsman 1/4" socket (1/4" drive). The required

torque seems very excessive for 1/4" tools. Larger tools have trouble

reaching one of the 2 large torx screws. Is the answer a better tool (3/8"

drive torx bit?), to more easily apply more torque?

Engine is completely @ ambient temp (~ 55 dF).

TIA,

- Dave; '95 854T, 105K mi
