I wrote many DIYs for E39 forum so I am very familiar with the E39 setup.

I come from E39 (1998 528i), so we do cooling overhaul as preventive maintenance.

When I did that, I replaced most items in the cooling system. I wrote it up below for the 1998 528i:
ENTIRE COOLING SYSTEM REPLACEMENT Tips and Tricks (Very Long, Enjoy!)


Now, for the 2006 X6 3.0L MT with 113,000 miles, I am thinking out loud as preventive maintenance:

REPLACE:
1. Thermostat by Wahler, PN 11537509227 $55
2. WP by HEPU $62 (I have had HEPU in my E39 for 8 years, zero problems)
3. WP Pulley b/c this thing is plastic and usually cracks at 140K or so. It is cheap at $22.
4. Reservoir: BMW PN 17117573781, $76. This is b/c I saw some posts where people reported cracked reservoir at 125K.


CHECK AND REPLACE IF NECESSARY:
1. Fan Clutch
2. Fan Blade
3. Pulleys x 3 (incl AC system)
4. Belts x 2

KEEP:
1. Radiator because it rarely leaks before 150K.
I have had good success with Nissens radiator in my E39 for the last 8 years.
Anyone here has experience with Behr?
2. Radiator Hoses x2 because it rarely leaks before 150K.


Any opinions will be welcome!

I have 74k on my '03 5MT, and previous owner replaced expansion tank, hoses, and Tstat with OE items before I purchased the car.

I did the 3 pulleys, and 2 belts within the first year after purchase, and my indy noticed that my fan clutch was shot at the same time. As far as I know my WP and WP pulley is original although I have to check my receipts, as well as the fan blade. Due to age I may do the fan blade and water pump within the next year or two and a full cooling flush and fill.

Good write up - except for the

I then took my garden hose to the lower radiator hose and let it run until the fluid coming out of the radiator drain was clear and not the blue-green colour.
You shouldn't use tap water in the cooling system at all, if you want to do a complete flush you should drain it from all drain points (radiator plus engine block) then put those plugs back in refill system with distilled water and run for 5-10 minutes with heater on, and then drain again from all points. With the distilled water you can add a radiator flush additive if you like.

I am wrestling with that lower hose right now. Broke the transmission thermostat in the process of removing the tank. Real PITA.

Got it off using a small pry bar from underneath to loosen it just enough to wrestle it off from the top.

Got a new thermostat from Napa for $86, expensive but they were able to special order it and have it to me in less than 24 hours on a weekend. If it was Monday I would have ordered it from Oembimmerparts and had it overnighted.

Hi everyone,

Awesome right up! and thanks I just joined the forum even though I've always been reading and viewing the posts. Almost over 6-7 years ago I was part of a X5 forum I believe it was called X5World and now I think is Bimmerfest.

I got a 2004 X5 3.0 E53. I try to do most the basic maintenance on it, love the truck, I also have a 1998 R1200C BMW Bike- Also known as the Bond Bike from Tomorrow Never Dies, love working on that also.


I just had a few Q on this DIY--


1. I have a 2004 X5 3.0 E53- Would this DIY be that same?

2. The O-Ring that comes with the Water pump, is that the same O-Ring that was put on the Aux Fan Switch?

3. This Spring, I'm gonna replace my Thermostat as it gone haywire due to the one day we had -25C temps with Out Wind Chill and with Wind Chill it was was over -34C. The Thermostat got stuck open and I had very little warm air coming in the whole day and the needle was just running above the totally cold mark even after an hour of driving.

Now with the weather normal the car does heat up just below the middle I think it should be at middle after an half hour-hour driving right? Do you think the Thermo is shot or was it just that one day it got stuck and I should definitely replace it?

4. I have only 137,000 KM- (KM Not Miles) that like 85 K Miles. Shall I do the waterpump and hoses also? even thought they are ok? I know the preventive maintence says at over 130 k MILES.


Thanks for you help guys!

1. Yep - effectively the same engine.

2. No, the Water Pump has its own O-Ring. You'll have to purchase the aux-fan o-ring separately.

3. Definitely sounds like a stuck thermo. Regardless of the outside temp, the motor regulates its own temps so it running cold for over an hour tells me its a stuck thermo.

4. its up to you but i'd say this: the water pump is probably good for 150k miles, easy. Hoses are mostly damaged by heat so given you're in Toronto, it's not exactly excessive heat however the car is now 12 years old so might be worth it esp if you do a great deal of long distance.

Thanks Wayne for the answers, perhaps I will leave the water pump, as I only have 136 KM and 150 Miles is around 240 KM, so I got just over 100 Km to go for the pump.

I'll probably change the hoses as I am doing the thermo anyways as well as the o-ring for the fan.

Thanks Again!!

Just replaced the water pump on a 3.0 e53 X5. I couldn't get the pump to seat far enough to get the nuts started. Used a little lithium grease on the o-ring and edges of hole in the engine but no matter how hard I tried couldn't get it to seat.



I was afraid of damaging the radiator so used a 2x4 about 5 feet long to rest on the top and bottom of the radiator and used a rubber mallet and piece of wood to span the distance to the pump. It provided the leverage to gently push the pump directly into the engine and it easily popped into place.
