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 change a fuel pump regulator in a 2001

The fuel pressure regulator is located in the fuel rail, held in by a torx screw.

Release pressure from the system by cranking the car with the fuel pump fuse out, or byt depressing the relief valve on the end of the fuel rail.
Unbolt the regulator/housing assembly, unhook the vacuum hose, and remove the regulator/housing assembly.

Installation is reverse order.

If you need to replace the regulator that is located in the fuel pump, it is not serviceable. Luckily they rarely fail.

What can be done if a radio reads off when switched on after battery has been temporarily removed?


You will just have to re-set your stations, etc. Very common when the battery is disconnected or removed. In case the code is lost, I taped mine to the top of the radio and kept a copy in the glovebox. A dealer should be able to supply a radio code from your registration.

My Volvo is overheating and mixes the engine oil with the coolant, however,there's no sign of coolant and oil mixture in the engine, only in the radiator and coolant lines. The oil cooler is also clean....


the oil that you are seeing may be transmission fluid if its an automatic,the transmission lines go through the radiator for cooling.if the radiator fails in that section ,it could be leaking into the antifreze,or you have a blown head gasket

Behind Headlamp remove wiring clip and tape it off. At the same time tie off the water pipe. That'll do the job quickly. Otherwise removing the whole wiper system isn't a big job.
