Vader was getting thirsty consuming about a cup of coolant while beating up p-cars at a recent PCA event. Inspection revealed the the area around the thermostat housing was moist. Since Vader has about 185 track days and 75,000 miles, I decided to get a lot done "while I was in there." Tischer BMW online parts offers a nice bundle including all the hoses, radiator hangers, core, expansion tank, pump, thermostat and housing, etc. with attractive pricing. The BMW CCA rebate further sweetened the deal. Nolte has experience with the cooling system of the e36, so I was thrilled that he offered to give me a hand. It turned out to really be a big help because I was suffering from post party mental deficiency syndrome Sunday morning. Things like the routing of belts and manipulation of plastic fasteners were mystifying to me. I am not sure we needed to replace the water pump since I replaced it at about 50,000 miles, but it seems like good insurance. I can report that the removed pump looked very good, just with all the black paint gone from the METAL impeller. The removed hoses were all nice and pliable without any dry rot and the infamous upper radiator hose plastic connection still looked sturdy. Even the plastic t-stat housing looked fine, but once it was removed it was clear was allowing coolant to spray on the front of the motor creating a green gooey mess. This job was actually easier than I expected and the only negative is that the block drain plug is situated behind an O2 sensor on the exhaust so when you open the plug, there is not any way to avoid a royal flush. I wasn't wearing goggles, and none got in my eyes, but I recommend eye protection for others. We burped the system adding coolant while blowing the heat full blast and revving the motor to about 3000 rpm, and no more leaks! Thanks again Nolte.
