Where is the thermostat located on a volvo s40

Instructions

1. • 1 Open the engine hood by pulling the hood release latch located on the lower kick panel on the driver's side of the Volvo S40. Lift the hood up and prop it on the hood prop.
     
   • 2 Locate the steering shaft that extends from the firewall to lower suspension located inside the engine compartment, by the front right wheel. Halfway down the shaft, you will locate the power steering pump. The pump is a black container that bolts to the driver's side of the engine block. On the top, you will find a cap that says "Power Steering Fluid."
     
   • 3 Look to the left of the cap. Bolted to the power steering pump is the thermostat temperature sensor. The sensor has a black round cap and a black wire extending out of the top.

You need to look at the temp sending unit it's probably faulty anthor issue with volvo is dirty throttle body's this raises havoc on the car they idle up down all over the map also you should change the thermostat too as a precautionary measure make sure it's the right temp for your year of your car thanx Chris

I would change the thermostat with the OEM adn it should be fine, the ECM needs to see a certain engine tempreature to control fuel ratio.

Could be a bad (VSS) Vehicle Speed Sensor. Check it its located on your transmission. Good luck

I recently took my car in for this problem. The thermostat was replaced a year ago. This time they replaced the thermostat and the IAT (air intake temperature sensor). The thermostat was 20 and the IAT was 50, with labor it all came to $140. Most sites online that I found suggested replacing both the sensor and the thermostat at the same time. When the thermostat goes, it usually takes the sensor with it. So I'd have them replace your sensor too. Good luck.

Its really easy... open the hood... looking back toward the car, its at the front of the engine, left hand side near the top... you'll see the hose coming out.. its held in with 2 large torx screws... make sure you change the rubber seal around the thermostat when you remove it.. also be aware some antifreeze will leak out.. so take proper precautions.. don't do it when the car's hot.. difficulty 1/10.. easier than an oil change.
