quick question on warm running device
« on: April 30, 2020, 12:58:04 »
My WRD thermostat extends only 4mm it is not enough to shut off air.I thought I read somwhere that it should extend 7mm.I believe it is the newer type on a M130 1972 engine.Does anybody know the part number and who sells it.
Thank you in advance.

Not too expensive either. Sounds like yours needs replacing.

Also make sure that the inside of the housing is clean of all the rust that can accumulate there.
