  1. BMW X Series - Tech Talk For All Gen Of X Series
    Hi guys. Looking to do a coolant change on our 2012 X3 as judging by the service history it has never been done, I can understand why as there doesn’t appear to be a drain plug for the radiator anywhere which suggests I need to remove one of the lower radiator hoses. However, these are held in...

    Hi, My question to keep things short is when should the radiator fan come on? Background... I have been having issues with my radiator fan. Wouldn’t come on even when AC was on. Sometimes it would come on with the AC and then stop. An error code was showing for the fan as well hence I...

    Hi guys, I had my main thermostat replaced on Friday last week. Since then I've noticed a coolant leak at the lower hose connection where it meets the thermostat. If I wiggle to pipe the leak gets worse. Are there o rings inside the hose connection where it meets the thermostat? It was...

    Hi All, My 630i has been sipping coolant for the past while but is now at the point where I've been able to locate the leak (bottom corner, automatic transmission oil heat exchanger side, where all the dirt/leaves collects and rots behind the grill.). With all the plastic housing around the...

    Hi guys, having a nightmare with my 645ci. The thick top pipe that feeds the rad, keeps blowing off and spraying all my coolant over the place. I put 5l of new coolant in the other day, a new jubile clip to hold the pipe on, and took it for a 10 minute drive. Needless to say that the fastest...

    Hey All So I need a new fan according to the diagnosis by a local independent specialist. Apparently it is throwing up some error codes. My car had been overheating when in traffic jams. I have been quoted getting on for £800 to repair this; I believe the fan is £719 from BMW. From what I've...

    Morning all, I fitted a new radiator in my 325Ci over the weekend as the old one had a leak and I've been topping it up with the antifreeze/coolant and water as you do, but despite bleeding it repeatedly I can't seem to get it to fill up to the max. This morning I tried to do it again in this...

    So in the process of draining my coolant I removed the radiator adjustment screw, the bit that the radiator drain plug screws into. It looks like it needs replacing once it's been removed however I've run into a strange problem. The one I took out of my E46 330i looks like one from a later BMW...

    Hello, I have a E90 318i and just recently regased the air con and changed the coolant, I noticed that the radiator fan does not spin at all. Apparently it should start spinning if the A/C is turned on but it doesn't. I have checked the fuse box (No 67 and 69), link below for reference to the...
