Clanky Posted January 25 Report Share Posted January 25 Does anybody know if the thermostat in a Gardner is engine specific? Or are they just a rebadged car engine thermostat for instance a ford cortina? Link to comment Share on other sites More sharing options...
Tony Brooks Posted January 25 Report Share Posted January 25 In a very general way, probably, but the opening temperature may be different to any specific vehicle. Then there are three different designs ignoring bellows type and waxstats that are interchangeable. The ordinary type, plus two designs of bypass thermostats. If you don't have a parts list and manual, you need to get your old one out to see hat type it is and its opening temperature. There are a few "odd balls" that are not likely to be yours. In hose stats as used on older Renaults, and flange mounting ones in varying diameters. Link to comment Share on other sites More sharing options...
matty40s Posted January 25 Report Share Posted January 25 They are not Gardner specific, but you want to look for the lower temp one, not 82c Link to comment Share on other sites More sharing options...
Split Pin Posted January 25 Report Share Posted January 25 (edited) It depends upon what type of thermostat housing that is fitted, if it is a a single type then unless it has been modified then it has a different type of thermostat with the bypass cut off as a sliding vane attached to the outside (No 27). They are larger in diameter than the twin housing which uses a smaller one (no 30) more commonly found in older vehicles (2" dia from memory.) The later type https://gardnerspares.com/product/74-degree-thermostat-drop-in-unit/ Edited January 25 by Split Pin Add picture Link to comment Share on other sites More sharing options...

I also have a feeling that one marinises of these units did their own thing, so there might be yet another possibility. Link to comment Share on other sites More sharing options...
Clanky Posted January 26 Author Report Share Posted January 26 (edited) Thanks for the replies. This is the housing if it helps. So it looks like no 30 on the illustration above? Are these easy to find? Edited January 26 by Clanky Detail Link to comment Share on other sites More sharing options...
Split Pin Posted January 26 Report Share Posted January 26 (edited) That is the later twin thermostat type, so the one I linked to is the correct type. Are you looking for one that is a different temperature to the one that you have in? This is the correct type https://gardnerspares.com/product/74-degree-thermostat-drop-in-unit/ It says its for LXB but the housing that you have was used on both the LW,LX and LXB Edited January 26 by Split Pin Additional info Link to comment Share on other sites More sharing options...
Clanky Posted January 26 Author Report Share Posted January 26 Thanks, yes id like to put a 74 deg one in as the water doesn't seem to be hot enough Link to comment Share on other sites More sharing options...

Do you mean the engine coolant or the domestic hot water? If the latter is there a thermostatic mixing valve fitted to the domestic system. Often very close to the calorifier, If so, is it working and/or correctly adjusted. Link to comment Share on other sites More sharing options...
