Pic diagnostics
 

The X5 was parked for 5 days. I received these pictures after it was moved. Since it was not turned on during that time, I assume it's coolant. At 162,000 miles, it's time. I have been topping it off during this hot summer. I figured the problem might be the 1.2 bar relief tank cap. Guess not. Being parked all the way over to the driveway edge, it's the left engine side. Today, I'll take a flashlight to look under the water pump. The pump was replaced before purchase. I've only replaced a few hoses and thermostat.

Any tips before starting the work? A box full of OEM parts is ready to go. Plus a a new CCV system. Should I put it up on ramps so parts are easier to reach? Or use wood planks to raise it a few inches?

Confirmed coolant leak. It's the lower radiator hose seal. I didn't see any along the block front plate. Ordered a few more replacement parts from FCP. Tear down begins today. I'm flushing out the green coolant the previous owner put in it. BMW blue coolant will go back in.

Progress pic. The intake is completely loose. Disconnecting the fuel line, knock sensor/temp sensor plugs and harness zip ties are left to completely pull out the intake. A little clean up will be done before replacing the pipes and hoses. One TB bolt was dropped. I'll have to look for it. One DISA valve screw stripped. :( New DISA valve bolts and other small parts were ordered. Hopefully FCP shipping is on time to put it back together by the end of this week. :bmw:

@161250 miles, the OEM pipes were failing. I'm surprised they didn't leak! New OEM pipes are installed.

Wow, why do you YouTubers reach down to the lower fuel hose connection? It's much easier to remove at the top! The fuel rail was not removed. The entire intake was cleaned. A brush and cleaner work good.

Is this a cold CCV system? It has foam on it. I left it on. The manifold upper return hose broke. I'll have to order another one.

The piece I didn't count on breaking was the transmission thermostat. It broke apart trying to remove it. A new one will be ordered. Once a new thermostat is installed, the system can be filled for testing. The oil cooler has new o-rings too. Any hose that was not included in a kit had new o-rings installed.

Yes, W/foam is the cold weather CCV. IIRC the other part of the cold weather package is a different dipstick tube.

Oh! Do I need to order a hot climate CCV? I'm going back today or tomorrow to clean off the engine. Plus, the other areas I have not been able to clean or pressure wash. I still need to remove the dipstick for a new o-ring. Since I have to order more from FCP, it will be 2-3 weeks before it's all back together.

Nice updates

Thanks

All the other emission pipes I broke have arrived. Plus, a replacement for a broken transmission thermostat. I'll put in as much water as possible and try a pressure test. A soapy spray bottle should help. The engine won't turn on until the intake is installed. Plus, I dropped a TB bolt I need to find. Otherwise, I need to find a matching bolt at a local bolt store. A little more engine cleaning before installing the intake. Another good afternoon should be enough to button it back up. I'll replace the shroud later. Pic coming of it.

Ok, after almost 3 weeks, I'm back to finish a coolant system refresh. It feels so long ago. I need some help! I can't remember where everything connects. I did a test fit of a few parts. One new intake hose drove me nuts. I couldn't see where it supposed to connect. Finally, after flipping over the intake, I realize the hose connects to a hidden intake port. Hidden between runners. Some one has been down deep in it. The dipstick bolt was not even bolted down. A new seal should stop the leak there. The dipstick hose to CCV is also new.

Here is some eye candy. I'll post on items I need help to ID.
