Volvo Radiator, Thermostat and Sensors Your cooling system's temperature controls include all coolant temperature sensors, Volvo thermostat, Volvo radiator or expansion tank cap, cooling fan(s) and fan clutch (if equipped). These cooling system parts function primarily independent of the engine but control the engine either through cooling or by sending control signals to your Volvo's electronic systems.
The Volvo thermostat is a spring-loaded valve that opens and closes based on the temperature of the coolant flowing through it. A high temperature reading followed by a drop to normal temperature (or a continuously low temperature) is a common first sign of a sticking Volvo thermostat. However, many other conditions may cause these symptoms, so you need to know how to eliminate each possibility.
The Volvo radiator or expansion tank cap is also a spring-loaded valve reacting to system pressure. It serves to maintain proper system coolant level at predetermined pressures. It must always be replaced with an exact replacement cap with the same pressure setting. Never use other caps except for short-term emergencies!
A belt-driven fan blade for pulling air through the Volvo radiator is usually on the Volvo water pump pulley and should have a fan clutch to control it. The fan clutch allows the fan to turn with the belt at low engine speed and "free-wheel" at higher speeds. A bad fan clutch either doesn't allow the fan to spin at low speed (overheating in traffic) or doesn't allow it to free-wheel at high speed (potential overheating on highway or reduced gas mileage).
An electric fan can be either by itself (usually front-wheel drive) or auxiliary (used with a mechanical fan). Both types are controlled via a temperature sensor - in the Volvo radiator or upper Volvo radiator hose or on the Volvo thermostat or Volvo water pump housing. This sensor is usually an on/off type switch with a fixed temperature setting. (Some vehicles may have 2-3 settings for multi-speed fans.) This sensor is commonly called an "auxilliary fan switch".
Other common temperature sensors are: 1) gauge sender (variable output); 2) warning light sender (on/off type); 3) lambda and/or fuel injection sensor(s) (variable to control fuel injection settings); 4) thermo-time switch (cold start valve control). Your Volvo may have other sensors as well.
Temperature control is critical to both performance and emission control. Unfortunately, this system is the most difficult to troubleshoot without proper equipment and diagrams. It's even more difficult with computers that adjust timing, idle speed, vacuum and fuel delivery automatically to make up for potentially faulty temperature sensor signals.
Maintenance of your cooling system sensors is virtually impossible since there's nothing really to "maintain". Keeping them clean both internally (coolant replacement) and externally (engine cleaning) is the best way to ensure trouble-free driving. Checking and replacing all parts at the factory-recommended time or mileage limits helps as well

SOURCE: How do you reset the check engine light on a volvo

The Check Engine light has nothing to do with changing the oil. The light is on because there is a problem with the emissions system. Even if you reset the light it will just come back on unless the problem causing it to come on is repaired. You will need to have the ECU scanned with an OBD2 scan tool. That tool will retrieve the code that has been set by the ECU. The code will tell you what part is being effected, but not necessarily what part or parts are defective. To determine that takes training, experience, and diagnostic skills. I suggest you seek professional help. If the engine is running fine there is no hurry but if it is not running as it should, then do not put this off.

SOURCE: My 2006 Volvo S40 does not have an oil leak but it

have you tried to run finger around inside of tail pipe to see if its burning oil!! but do this when it is cold. you may also have bad oil rings on pistons. if it is burning oil it will smoke very little if any. because the convertor runs so hot it will burn up all the oil residue. so you may noy be able to see any smoke. have a good day!! check carefully all gaskets for oil leaks, and also make sure oil filter is hand tight, sometimes a loose oil filter will start leaking oil.

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

I have volvo s40 2004 The engine light comes


Sounds like your dealer is feeling its way. which sensor did they say they changed and why. Do not pay for this ****, you took it to the dealer with a warning light and they say they changed something in order to attempt to cure the warning but they failed. About as much use as changing the seat covers and emptying the ash trays! When you say noise, is this a squeal, a crunch, is it continuous or is it during change gear. Does the car slip when in gear, is there vibration. Check your engine oil and transmission oil levels

Vilvo s40 serviced in june; engine oil warning


most definitely the cylinder head gasket is gone.the oil does not just disappear,it finds its way to the radiator,i.e. mixes with the water.unplug the rediator cap with care(when the engine is cold)and u will see some kind of sludge,creamy colour,which confirms that the cylinder head gasket is burnt.u need an engineer to do the job for u.

I have ust serviced my 2001 volvo s40 and now the


did the sevice light come on before you serviced it? when you "serviced" it I assume you changed the oil and now need the service light reset.
I bought the 1998 S70. it got time to change the oil. Being how I am I changed the oil myself. I had to call dealership about resetting the service light.
they said $29.96.
I said 29.95?!!! how much if YOU would have changed my oil and reset the light?
they said $29.95.
so I learned you need to access the OBDII to reset the light.after service. hope this helps.
