We have a late 2012 (12-12) T 800 with 12.9 paccar. The heater control valve is $ 140 & all it needs are the little rubber rings that seal the inlet/outlet copper connections to the valve body. Any leads on where to find them ? Also we need the fan/water pump belt tensioner & the idler pulley, have not priced them yet at KW but am sure somewhere else will be cheaper! TIA
cheaper source : paccar 12.9 tensioner
