FAILURE OF THIS PART IS THE NUMBER ONE REASON FOR AIR MASS SENSOR FAILURE Many gas powered Volvos have a simple, thermostatically controlled shutter valve in the air filter box. Generally, the thermostatic valve will fail in the pre-heated air position. This routes super heated air to the air mass

The metal battery tray is subjected to acid from the battery. The acid attacks the metal, and, over time, eats its way right through the tray. The threaded hold-down can lose its hold, and this can leave the battery hanging by the terminal wires. Replace the tray and get the hold-down clip and four

CRC Mass Air Flow Sensor Cleaner is the safe and effective alternative to "underground" methods of MAF sensor cleaning. Don't us aggressive chemicals like brake parts cleaners or carburetor cleaners on MAF sensors. These can cause serious damage to sensitive parts. Use CRC MAF Sensor Cleaner -- It'

If you have a Volvo that was made between 1981 and 1989, and the main engine harness has not been updated, you should inspect the wiring harness at every oil change for signs of failing insulation. Several problems can occur, often intermittently, such as mixed signals to the instrument cluster, int

If most of your harness is in good condition, we offer original equipment single repair wires that are 40" long with the correct female connector on one end (you'll have to splice the other end from the wire being repaired). We also offer prefabricated repair harnesses to reroute the harness that go

When making engine modifications to your Volvo you can make fine-tuning safer by monitoring the air fuel ratio. There are elaborate analysis tools available, but they can be cost prohibitive for the do-it-yourselfer. Most people don't realize there is an analysis tool already on their car and all yo

The European ceramic style fuses used in all Volvos 1962 to 1993 (except the 700 & 900 series) can sometimes be hard to find. Better auto parts stores will have them, but it’s unlikely that you’d find them at a gas station. For a few bucks you can get our kit to replace all the fuses in your car an

Not sure how much fuel is in the tank? If your sending unit is original, that means it's "reaching it's golden years." The common "starting to fail" symptom is an inaccurate gauge that momentarily pegs at full. It might work like this for years - and it might not last another week. Put an end to unc

Coils rarely fail but when they do you're not going to be driving until you replace them. We sell Bosch coils that will give you long and reliable service. Like most electronic products, there is no return on installed product so diagnose your components carefully.

240 owners often complain that their heater motor and radio work intermittently or that their car will not keep running unless they turn the ignition key back a little bit from the normal running position. The most common problem is the electrical switch behind the ignition key. This part fails whe

The ignition transistor unit is sometimes called the control module, power stage or ignitor, and can be considered as analogous to points on earlier model vehicles. If this fails you will not have any spark and the car will not run. As with most electronic parts there is no return on installed tran

Oil Pressure Sender/sensor for dash warning light

An oxygen sensor allows your engine to run as smoothly as possible, because it measures the exhaust gases and relays information to the fuel system control unit. With this information the control unit can fine tune the fuel mixture for optimum fuel economy and power. A dead oxygen sensor can also le

A great tool to speed along valve adjustment is the remote starter switch. By connecting it to the battery + post and the red wire on the service connector under the hood you can manually 'bump' the starter over to close each of the valves prior to adjustment. Please note that if using this tool on

If you have a 1976-1995 4 cylinder Volvo with marginal or damaged spark plug hole threads, you can now make a quick, professional repair in minutes without removing the cylinder head. Kit includes everything needed to permanently repair 2 spark plug holes. Works on all B21, B23 & B230 engines. Remem

These models are equipped with circuitry that is designed to keep the coolant temp gauge needle positioned in the normal zone (9:00 position) even if the engine is running a bit hot. The idea is to prevent minor variations in coolant temp from causing worry for the driver. As these cars age a commo

If your Volvo has been fitted with aftermarket lighting equipment, a high powered stereo or other electrical accessories, your charging system may not be up to the task. We now offer an adjustable voltage regulator that will allow you to preset the operating voltage of the charging system and keep t

For owners of 1982-89 non-turbo 240 series Volvos, here’s a chance to put an end to intermittent electrical problems with our watertight fuse holder system. With the Bosch® LH fuel injection system, current is supplied from the battery to an exposed blade style fuse. This addresses the problem. The
