ajh Posted February 17, 2012 Share Posted February 17, 2012 On the 200TDI thermostat upper housing (HRC1574) there are two cylindrical casting extras. Are those there for any particular legacy or optional reason? Quote Link to comment Share on other sites More sharing options...
western Posted February 17, 2012 Share Posted February 17, 2012 the HRC1574 is not a part number, just a pre machined casting number, the 2 bosses are drilled & threaded for air condition fitted vehicle. see page 191 item 4 http://www.retroanac...V8_p168-299.pdf Quote Link to comment Share on other sites More sharing options...
ajh Posted February 18, 2012 Author Share Posted February 18, 2012 Ah, thanks that explains it. So removing them isn't a problem. Quote Link to comment Share on other sites More sharing options...
jbs Posted February 18, 2012 Share Posted February 18, 2012 I've used one of the extra castings on mine for my electric fan thermo switch-got it drilled and tapped at my local engineering place John Quote Link to comment Share on other sites More sharing options...
western Posted February 18, 2012 Share Posted February 18, 2012 Ah, thanks that explains it. So removing them isn't a problem. not on a non air con behicle just make/fit a blanking plug to prevent leaks. Quote Link to comment Share on other sites More sharing options...
