All seals, hoses needed for suspected coolant leak

[riazabzal]

Hi all,

I have a coolant leak on a 2014 Q5, I suspect it is the oil cooler or the EGR cooler in the valley. I do not see white smoke so I am thinking it is the oil cooler at this point. Can someone provide me with a list of part numbers of hoses and seals I should replace when going into the valley to replace the oil cooler? Any guidance would be appreciated.

Thanks,
Riaz

It is also a good idea to replace the

EGR to thermostat hose(although it is not critical since it is easily accessible)
059121103H

and

bypass valve hose to intermediate flange
059121625C

059121625C bend is very shallow, like 5 degrees, which is practically the same as how bulk heater hose comes off the reel.
You can smartly save a few bucks with good quality heater hose (u can buy 1 foot only) from any auto parts store and cut it to exactly 75mm.
Maybe they will sell you even less lol.
