While compacting boxes of "good stuff", with a view to more room and a visit to the scrappie, I came acoss a inline thermostat from a Isuzu 4WD (Trooper?), a friend's, I re-engined a couple of years back. This is hosed into the oil cooler line and marked 76.5ºC. Although it is hosed with 17mm?, the body is cylindrical and would take 1-1/8" hose. Thought it could be of interest to those that have cooler running engines..
