Koolman Thermostat
2008 135i
At approximately 88,xxx miles my water pump stopped working. I got a replacement pump and thermostat w/housing. Pump came with new Al bolts and went in fine. Thermostat however would not fit properly. The smaller diameter fitting did not simply "snap" in and required a lot of force. The larger diameter clamp fitting would not go in completely. I felt if I continued to apply more force that it may crack the female fitting and/or elbow. I ended up replacing only the water pump. Overall, the gauge indicates slightly lower operating temp I took some T-Stat measurements out of curiosity. Oem Inlet OD - 38.40 mm Oem Fitting - 45.68 mm Koolman Inlet OD - 39.16 mm Koolman Fitting - 46.20 mm OEM inlet OD Koolman inlet OD OEM Taper/Fitting Koolman Taper/Fitting Koolman T-Stat Just wanted to share, maybe save you the trouble. Also wanted to see if anyone else has experienced this. Were you able to get the T-Stat fittings connected? |
