Volvo D5 Thermostat Replacement - How To DIY - V70 S60 S80 XC90 XC70 P2 2.4 Euro 3

After doing the job and refilling the coolant be sure to squeeze the hoses with the engine running and once the engine has warmed up the vents are blowing hot air into the cabin. This engine isn't prone to coolant airlock but it is possible. You may fill the system but a few days later have to top up as any remaining air is eliminated from the system. After a few days, with the car cold, check the level and top up as necessary.

Thanks for yet another D5 DIY tutorial :)

This was so helpful, thanks mate.

Glad to help, thanks for the feedback!

Excellent I had no idea we’re the thermostat was, never mind how to change it so brilliant tutorial as I am done with paying people to work on my XC70 thanks.

Another helpful video on how to change the thermostat & housing. Let’s hope that the insurance gets sorted out soon. Cheers

Perfect!! I have this to do on my '04 XC70 - slight leak from the thermostat housing (I use green coolant) and getting to that bottom torx bolt was bothering me - nicely filmed and put together vid. Very much appreciate the effort putting this together.

Thank you for the feedback and best of luck with the job 👍

Thank you for the great video - just like your other Volvo ones I have watched - you do very clear presentation of the steps needed to complete the task. I have recently done the exact same job on my 2006 Volvo S60 2.4D with the Euro 4 diesel engine (291,612 miles). I found that you don't need to remove the under body trim beneath the radiator as there is a service hole directly beneath the drain screw. The thermostat unit for the Euro 4 engine is part number 31293698 and it is the same size and dimensions but with an additional hose connection. I would recommend using the Volvo metal gasket between the engine block and the thermostat and not 'instant' gasket. The metal gasket is part number 8636573.

[@IAMASPANNER]

Thanks for the information which will help others. I don’t think mine has the service hole you mention. As long as the thermostat isn’t leaking there’s no issue but if there’s a gasket available then fair enough, mine didn’t have one fitted originally.

Pretty funny that my steering pump pulley is damaged in exact same way 😅. Nice video, gained some knowledge on D5 maintenance.

I’ve finished the job, but thanks anyway 😊

I had to do my 2013 XC90 D5 Thermostats at 7 years! I was shocked it would fail so early. The easiest way to know you need to replace it is that the temp needed needs to stay in the middle with in 5-10 of running the car in 10-20 Degrees celsius. If the temperature needle is not dead set middle, change it. Also found DPF regen is not triggered if the car struggles to get to temperature so you may get a "clean DPF" message.

Hi Another great video as always I have a 2002 S60 d5, How long does your car take to get to running temp now ? Why did you not just change the thermostat itself, Thanks Dave

[@BLOCKsignallingUK]

I wonder if the old thermostat had an intentional hole in it. I believe some other makes of cars have a small hole to help bleeding of their cooling system, but too small of affect warm-up.

[@DerHoopdy]

You mentioned that the 6 speed conversion has increased your mpg, why would this be? Is the FDR of 6th gear higher and causing the car rev more at speed compared to the 5 speed?

[@haralduhlvinghansen709]

What size is the torx key used to remove the bolts for the thermostat housing?

[@gerardjones7881]

T30

Hey man. Love the videos of the V70 I’ve just bought a 53 plate V70 2.4 D5 Everything runs perfect, it’s sitting just under 200k miles. However, it’s loosing coolant, not lots, but enough to need topping up every two weeks or so, however no sign of coolant anywhere, the heaters work perfectly, it doesn’t overheat. I’m doing the belt & pump soon as it’s due, I’ve read online that sometimes the head gasket can go on these engines, causing the car to loose coolant over time, have you heard of this? Thought I’d ask as you obviously know Volvos a lot better than myself! Cheers man

[@NeilD163]

If you have no visable leaks in or around the engine bay you need to check the carpets in the car, the heater matrix may be leaking, as a rule unless it has been seriously abused and neglected head gaskets rarely fail on the D5.

[@joeyuk000]

What type of coolant you use? I spent days to find any info about original or acceptable type. Theoretically it is G11 but my 2004 d5 has light yellow coolant now and I need to replace.

[@IAMASPANNER]

I don't know what's correct but you have a few options. I switched to blue. One of the most important things is not to mix colours.

[@joeyuk000]

Thanks. Of course I do not mix them. Chosed the Mannol G13 greenish coolant, disadvantage is it has phosphats so need to replace in every 2-3 years. Before new coolant I flushed the system 3 times with 17 liters of ionchanged water. Strange thing only about 5.5liters of coolant I could drain from the engine drain plug and the radiator hose at once, manual says 12.5 liters…
