Replacing Radiator Fan and Thermostat 2010 V70/XC70 P3

Not one of my best filming jobs...had the footage and figured I should probably post anyway. Replacing the fan addressed my issue completely and I have not had any re-occurrences of engine overheating. As I mention in the video replacing the thermostat at this mileage (255k km / 160k miles) is probably a good idea. The housing on mine was quite brittle and parts of it disintegrated when I took the old one out.

Thanks for explaining car symptoms and diagnosis testing. Btw I’m scared to death of turning that petcock and braking it. Always remove the hose

Replaced my Thermostat and all the coolant and Radiator Hoses (9 in total) new coolant, Reservoir at 47,000 kms in my 2009 XC70 3.2 a week ago and the Thermostat was disintegrated like yours at very low Kms. It’s more a time issue then distance travelled. Volvo should of recalled it.

Wow, that’s nuts. Why cheap out on such a vital part. Thanks for sharing.

I changed thermostat housing and fan on 2009 s80. It’s very tight spots. Don’t have to take off anything. The fan pull left, then right, back and forth, it will come out just about enough room.

Perfect share. Thank you soooo much.

What was your car doing that you knew the fan was bad?

[@Bigtime_mcalpine]

Engine overheated and red light came on. When I started it back up later fan was non responsive altogether.

@@Bigtime_mcalpine There is another condition in which the fan/fans continue to run after the car is shut down. This indicates a bad control module, which is a very simple part to replace and can be found online for around 30USD. If the problem happens again with a new module, then the entire fan assembly needs to be replaced as shown because it is drawing too much power and will just keep shorting out the module. If the car is at ~100k miles or more, you should cut to the chase and just replace the entire thing to begin with.

@@thaddeusbatt9409 This exact problem, happened to me yesterday on the highway. Could you explain how to change the control module?
