Volvo B20 Engine Parts

If you have a classic Volvo B20 Engine, these are the parts you need.

Starter Motor

The starter motor is an electric motor that, when activated by a solenoid, engages the flywheel and crankshaft to start the engine. The starter motor is located on the front of your engine, and it’s connected to both the battery and the flywheel via drive shafts.

The starter motor is controlled by a switch in your vehicle’s fuse box or underhood relay panel. It should never be left in an “on” position without being engaged—doing so may cause damage to your engine’s electronics or other components. If you’re having trouble starting your car but cannot figure out why, make sure that there isn’t something wrong with either part of this complex system:

Fuel Pump

In a car, the fuel pump is a mechanical device that pumps gasoline from the fuel tank to the engine. When you start your car, this pump is activated, allowing it to draw gas from your vehicle’s storage tank and push it through a tube into the engine’s intake manifold. As you drive along, there are times when you may notice a clicking sound coming from under your hood; this sound is likely caused by your fuel pump kicking on and off intermittently as it regulates how much fuel reaches the engine at any given moment.

The Fuel Pump Is Located Where?

The fuel pump itself can be found in several different areas of your vehicle depending on its make and model; however, most often it will be located within close proximity of the gas tank (i.e., near where all of those pipes meet together). This is important because there are other components that interact with each other during operation (such as filters) so keeping everything close together makes things easier!


  • Carburettor

A carburettor is a device that mixes air and fuel together to create an explosion in your engine. It consists of a main body with multiple parts. There are two types of carburettors: float bowls and pressurised bowls.

  • Fuel pump

The fuel pump is responsible for pushing fuel into the carburettor so it can mix with air before being burned in your engine. There are two types of fuel pumps: mechanical and electric (different brands use different names).

  • Main jet / needle valve assembly

This part regulates how much air enters the engine at any given time, depending on how fast you’re driving or what type of terrain you’re driving over (hills, flats etc.). The number after “main” refers to how many jets there are; e.g., if it says “main” then there’s only one jet inside this part – if not then there would be two or more jets inside this part which would affect how much air entered through them per revolution.* Pilot jet / idle mixture screw


A distributor is a mechanical component that provides the ignition spark to the engine. It contains a rotating camshaft, which uses lobes to engage and disengage a set of contacts inside the distributor housing. When engaged, these contacts pass electricity from an ignition coil to your spark plugs.

When you replace your distributor, it’s important to ensure that it’s installed properly so as not to cause damage or malfunction. Below are some symptoms of a bad distributor:

  • A “dead” or weak engine start (turning over but not starting)
  • Poor running performance including misfire and hesitation
  • Poor fuel economy

If you experience any of these symptoms with your Volvo B20 engine, look into replacing your old distributor with new ones from AutoZone!

Oil Pressure Switch

An oil pressure switch is a safety device that switches off the engine if the oil pressure drops. The purpose of this is to prevent damage to your car’s engine as well as prevent further injury in case of an accident.

Oil pressure switches are usually located in an engine bay near to where the oil pipes connect up to it, and they’re often connected by a cable or wire to an indicator light on your dashboard so that you can see when there’s low pressure in your engine.

Exhaust Manifold

The exhaust manifold is a part of the engine that connects to the exhaust system and throat. It can be used to replace a faulty or damaged manifold, and it’s pretty straightforward to do so.

If you’re unsure whether your exhaust manifold needs replacing, check if any of these things are true:

  • Your car’s emissions are high enough; if they aren’t at least 7 grams per mile (g/mi), then consider replacing the intake manifold or catalytic converter instead.
  • You notice a clunking noise when you accelerate from idle speeds that goes away as soon as you start driving at higher speeds. This could mean your exhaust gasket is leaking, which would require an overhaul of your entire system rather than just one component replacement.”

Oil Cooler Kit

You should not be driving a Volvo without an oil cooler kit. It’s the single most important part of the engine that keeps your car safe from overheating, and it’s also one of the easiest things to install yourself.

If you have a B20 engine in your Volvo, this is what you need:

Fan Belt Tensioner

The fan belt tensioner, which is located on the engine block, helps to keep the fan belt in place. Over time, this part can become worn out and may have to be replaced. To change it out, first remove the old one from its mounting bracket and replace it with a new one. Make sure that you do not mix up your left and right side when replacing this part! Also remember that these are very small parts so be careful not to drop them while changing them out.

Once again, when changing out any Volvo B20 engine parts make sure you only use genuine Volvo B20 engine parts in order for your vehicle’s warranty to remain valid.

Water Pump Pulley

  • The water pump pulley is a small, cast iron circular plate attached to the front of your engine.
  • The pulley is driven by the crankshaft via a belt, which forces it to spin around at high speed.
  • This motion drives a series of gears that turn the water pump.

Gearbox Speedo Drive

The gearbox speedo drive is a component of the gearbox that drives the speedometer.

It’s a small part, but if it breaks or wears out you’ll have to replace it.

Here’s how to do that:

  • Remove the three bolts holding on your gearbox cover and carefully remove it from the car.
  • The gearbox speedo drive is located on the left side of your engine where you can easily see it (see picture).
  • Use a socket wrench to remove this part from its position; be sure not to damage any other parts when doing so!

If you have a classic volvo, these are the parts you need.

If you’re not familiar with the world of classic car engines, it can be difficult to find the right replacement parts. You may be able to get some of these items on eBay or at a local auto parts store, but it’s best to consult an expert mechanic before making any purchases or installing anything yourself. This way, they can help you figure out which parts are best for your particular model and year range and make sure they’re compatible with your engine type and model.

If you have access to a mechanic who specializes in restoring old cars (or if you’re a skilled DIYer), then consider purchasing all these components online and ordering them directly from us—they’ll arrive ready-to-go when we send them out so that there won’t be any delays between receiving them and having them installed by someone else after we ship them out!
