Replace thermostat as preventative maintenance?

[EricG]

I'm going to be flushing the cooling system and replacing most of the hoses soon - including the PHH. Should I replace the thermostat at the same time? Or am I at the bottom of the bathtub curve and just fixing something that ain't broke? It's a 93 FZJ80 with about 145K on the clock.

I assume replacing the thermostat is straight forward. Anything I should know?

FWIW, I haven't had any cooling issues.

Yes.

You should be sure to get a gasket with the OEM thermostat. IIRC, the gasket is sold seperately.... could be wrong on this. The jiggle valve goes at 12:00 o'clock. Use care in fitting the gasket. It's a big O-ring. The housing is AL so the torque values are low.

Yes.

Thanks - can anybody with an FSM tell me what the torque values are?

pg. EG-176 of 97 LC FSM:
"Install the water inlet with the 3 nuts.
Torque: 21 N-m (210 kgf-cm, 15 ft-lb)"

By my calculation, 12 x 15 ft-lb = 180 in-lb. torque if your wrench is calibrated for in-lb.

Excellent - thanks!
