Positioned between the carburettor and the inlet manifold is the carburettor flange. A flange is a connecting piece between two components. Bolts and nuts are used to fasten the two parts together, preventing any liquids or gases from leaking out of the system. In the carburettor, fuel and air are mixed together. This fuel-air mixture then enters the cylinders via the inlet manifold to be combusted. The carburettor flange prevents 'false air' from being drawn in, which is air that has not passed through the combustion system in the carburettor. False air can carry dirt and grime from outside into the engine. This ultimately leads to contamination of the engine and can even result in engine damage. Therefore, make sure you can recognise the symptoms of a faulty carburettor flange so you can replace this part on time. Below we explain what symptoms you should look out for.
Carburettor Flange Defect
A defective carburettor flange causes a poor connection between the inlet manifold and carburettor. This allows contaminated air to enter the engine system. You can recognise a defective carburettor flange by the following symptoms:
- Poorly running engine: due to an excess of air, the engine can start to choke. This reduces engine power.
- The car idles poorly
- The car runs erratically
- An overheated engine
Continuing to drive for too long with an excessively rich air mixture will cause the oil film on the cylinder wall to disappear. This causes the pistons to rub against the cylinder wall, damaging the cylinders and pistons. Therefore, make sure you replace a defective carburettor flange on time.
Replacing the Carburettor Flange
Is the carburettor flange defective? Then it's important to replace the flange. If you have some technical knowledge, you can carry out this job yourself. However, there are several parts that you need to dismantle to get to the component, such as the air filter, the fuel supply line and the inlet manifold. This makes it a time-consuming and difficult job.
Are you having the carburettor flange replaced by a garage? Then order the necessary parts cheaply at Winparts. Parts are often cheaper online. In addition, the costs can be very high because it is a labour-intensive job. So you save money by delivering the parts to the garage yourself. This way you only have to pay the installation costs.
