Hi all, I am going to do my first water pump replacement on my 2009 BMW 528i with 85k miles on it. There is no problem or codes related to water pump but I am planning to do some travels and I do not want to have water pump issue in the middle of no where. I have already read many discussions...

2002 530I Ran a diagnostic test on my car and it said that my Auxiliary Water Pump wasn't working. The good news is that I understand that could be the reason why my heater has not been working. PROBLEM... where is this pump? I just replaced the Heater Control Valve, and the front hose on...

Hello, I was looking over my 03 525iT to get it ready for a drive cycle and smog test after abs module rebuild and noticed a few drops of coolant in the belts area and some coolant on the cooler line. I think it may be the water pump, recently replaced the thermostat and lower radiator hose and...

Hi, all. Time to give back, here, as these forums have always been so helpful. The repair: water pump and thermostat replacement on an AWD E60/N52 5-series (2007 530xi). I think this procedure is similar for E60 and E90 models with either N52 or N54 engines. Regardless, the procedure is quite...

Hey guys! I’m trying to get help on how to remove the water pump mounting support. I have a 2017 330i that is leaking right behind the water pump. At first I thought it was the water pump leaking so I replaced it. When I went to add coolant it all started to leak again from the same spot, which...

Hi all, I've seen many posts about the P20EE code but I haven't seen many posts about my particular issue with it. I have a 2012 X5 35d with ~65k miles on it that is showing the P20EE code along with 4D16, which I understand is the NOx sensor, catalyst, bank 1- efficiency below threshold code...

I have an 05 330xi that's had constant cooling system troubles. After I overheated back in November and stalled out, I replaced most of the hoses, the expansion tank, the thermostat, and water pump. I keep having persistent leaks dead center. No fluid on the pulleys so it definitely seems to be...

This is not a step by step. Sorry for those looking for one....if needed email me at [email protected] for one if needed..... That said, did this job tonight. Couple of things: Get to the thermostat and pump from the bottom. Use jack stands etc. or a lift. Make sure you have a 1/4 inch...

I keep getting this code 80436B "Auxiliary water pump: Short circuit to ground" popping up in my code reader, but never have had a check engine light. Code comes back in a day after I clear it. It is for the turbocharger cooler - anyone have any thoughts on this - should i just ignore - am...

Sitting at light, never had any problems with engine (coolant temp dead center, always)...boom! Top hose pops off radiator. Replaced thermostat and water pump. Same problem. To radiator hose gets hot and hard, then pops! If I loosen radiator cap, the pressure relieves (though the water...

My son has a 2011 328--I hooked up my Schwaben scanner and it's throwing the following codes: 2ECC/present BSD, message: alternator missing 2E85/not present BSD, message: electric coolant pump missing 2E81/not present DME: electrical coolant pump, speed deviation. When I spoke with him, he...

Hello, I had tried to start my vehicle a few weeks back while the outside temperatures were about -5 and in my garage they were about 30 degrees or so. I had the hot air on for 10 minutes and it was not blowing any hot air out of the fan, and about 1 minute after driving it around the block I...

My 08 just passed 90K miles recently. It was really cold yesterday (not sure if it is relevant...) and once the car dropped down to normal idle speed, I heard slow interval knock. It sounds like it is coming from the front of the block so I am guessing it is the water pump or one of the other...
