Snagger Posted April 23, 2022 Share Posted April 23, 2022 The valve goes on the left side of the head towards the back end. You will see one tapped hole that doesn’t fit the head bolt pattern. The plain Union goes into the thermostat housing main casting. Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted April 23, 2022 Share Posted April 23, 2022 Remember when looking in parts manuals, a heater come under optional equipment; you need the appropriate manual. Regards. Quote Link to comment Share on other sites More sharing options...

Thanks I have a solid pipe to run along middle, not sure if I need it or not but have seen others with it, Another pic from top, am I right in thinking that number 1 from heater goes to number 3, and number 2 from heater goes to number 4 ?? Thanks Quote Link to comment Share on other sites More sharing options...
Snagger Posted April 25, 2022 Share Posted April 25, 2022 Those are the locations, 3 for the plain union and 4 for the valve. You could be fancy and use a SIII valve which is operated by Bowden cable so that you can control the temperature from the cab, of course. Im not sure how the hose routing and clamping works on the SII - I have only mucked about with SIII, which has a steel pipe run along the left side of the head, secured with a bracket from the middle stud of the rocker cover, but that made sense as the heater matrix on those is on top of the left foot well on right hand drive models. I don’t even know the pipe routing on LHD SIIIs, but I’m sure there are plenty of pictures of SII and III engine bays to Google. Quote Link to comment Share on other sites More sharing options...
