It took me 10 mins of wresling to get it out!ġ0. Also check it if pulling on a any other hose. On the E70 it was very easy however with the F15 the A/C hose is in the way it obstruct the back part of the fan, the big upper hose is very stiff and the lower hose is very flexible just, trick is to slowly pull up and move the A/C hose away take care not to damage it. Here comes the pain in the PITA part, sliding out the radiator fan.
*R Passenger side (arrow shows location, push in to release)ĩ.
#Coolant for bmw driver#
*L Driver side (arrow shows location, push in to release) *On each side of the radiator there's a simple mount locking clip, its easy to release just push in (on both sides) and pull up on the fan and it come off the mount You must fold that in before removal of fan *Orange arrow is one of the upper mount it hinged so you can fold it in and clear the upper radiator hose.
*Red arrow is the bottom guide tabs nothing fancy they help slide in and holds the bottom part of the fan. But its actually very easy to unmounted (compared to other cars that I've worked on) from its bracket Remove the fan.Now this part is really hard to explain because there are so many things in the way, tight fit and multiple clips. Remove electrical fan plug 2 squeeze clips on each side and pull upĨ. Here's the radiator bypass hose attached to the radiator fanħ. Remove the Coolant hose that is attached to the bottom of the radiator fan, there's 2 spots (green circle) redline show's where the bypass coolant line goesĦa. Remove the lower splash guard (lower cover) 12-14 8mm bolts,Ħ. To slide them off use screwdriver to spread the pins apartĥ. Remove the 2x A/C Line Mounts, the line can be pop out of its holder just use care not to break the holders,Ĥa. Watch the wires and the hood release cable that are attached on to the stiffening cross bar.Ĥ. Remove the stiffing cross bar 4x 13mm bolts, These are torque to yield bolts its recommend to replace them after removal!ģa.
Remove the front fresh air intake trim cover 2 8mm bolts on each sideĢa Lift up and Slide back to remove watch the clips at the front take care not to break themģ. There's a coolant hose attache at the rear (to air filter) check and removeĢ. Remove the air intake snorkel, 4 clips holding in frontġa. *Air compressor (at least 5 gallon tank) for coolant vacuum toolĬoolant vacuum tool, this tool refills coolant, using vacuum, with little to no air in cooling system system, it also check for leaks. *At least 2 gallons of BMW blue Coolant 50/50 mix (Disclaimer this is a non-professional guide, I'm not responsible to damage or injuries or death, perform/use at your on risk) My 14 x5 35d is at 63k miles and almost 4 yrs old when i did this so its pretty close for what, I propose is due, for a coolant change.
Per BMW recommendations, coolant has a "Lifetime" service life, but do some research on G48 coolant (ie BMW Blue coolant) and they have a service life of 150,000 miles or 8 yrs.īut given how many components that relies on coolant (especially on 35d and 50i) its a safe practice to change your coolant at half of the recommended interval ie 75k miles or 4 yrs. This is a short guide to changing coolant in a F15 X5 35d (not the same for 50i or 35i), using BMW way, which i found it was more complicated that it suppose to be, I'll probally do this again in spring but in a more simplified fashion in that i'll probally do a longer guide.
