Cooling System Refresh

Post by m96ag » Thu Aug 04, 2016 2:04 pm

Hi guys,
I'm doing some preventative maintenance on my cooling system and I've replaced the upper and lower radiator hoses, the thermostat and temp sensor, the expansion tank, both heater hoses, the hoses going to the oil cooler, and both lines going to the expansion tank. Am I missing anything?

Thanks!

There is a real nasty one to get to that goes to the turbo and it is usually the biggest problem child of all of them.

Whoops. I forgot to add that I will do both turbo waterlines shortly. How bad are they to get to?

One is super easy. The other is super hard.

Use only Volvo hose or better. Do not use URO hose.

once you spin the screw clamp around with a hammer and screw driver, its not too difficult.

Definitely replace them, both of mine were bulging and the car didn't have man miles on it

Thanks for the tip. Definitely would not have thought of that.

You have

short one between water pipe and manifold
short hose to turbo
Short hose between PCV and thermostat junction

all three of which are pretty nasty on a FWD and downright torture on an AWD.

At 160K, consider radiator.

OEM vs Nissens etc., info in forum.

Lucky me. Do you have a part number for the PCV hose?
