Hello all,

I've had my V70 off the road for around 3 months (as I was using a 4x4 up here in Scotland for the winter months) and I've just got it back on the road (the best vehicle I've ever owned!). Im just about to do some simple maintenance on it including - Pollen/Air Filter replacement, Oil and Filter change as well as a Coolant system clean, flush and change. After having my V70 for over 2 years now and putting 20,000 miles on the clock, I think this is well over-due!

While I am doing a Coolant change, I figured I may as well change the Thermostat and Temperature Sensor as well (Not sure when this was last done and it'll save me from having to drain the system and do it at a later date).

My only question is where exactly is the Thermostat and Temperature Sensor Housing? I have read many forums that state different answers - Some say it is halfway down the engine block next to the alternator.. I can see that this is where the lower radiator hose goes into and it does look like a housing but there is no Temperature Sensor (that I can see) going there. I have noticed that the upper radiator hose goes into a different housing and there certainly looks to be a Temp Sensor there.. But that housing is rather small and I have read forums stating that the replacement Thermostats are too big for that housing?

Is there any possibility that the Thermostat and Temperature Sensor are located in two different housings? Or will they always be in the same one?

Any help on this would be greatly appreciated and/or anyone that has done this job before?

My Volvo is a 1999 V70 2.5 Diesel XTD - D5252T Engine.


Thank you!
