Dismantling and Cleaning the EGR Valve

Model: Honda Civic MK 7 - Years 2001-2006
Part: EGR valve

The EGR valve is exposed to exhaust gases that generally contain oil particles and unburnt diesel, which tend to clog the valve: therefore, a simple cleaning can restore its function. It is also advisable to clean the manifold to which the valve is connected, as combustion residues can also clog the manifold itself. For the vehicle in question, dismantling the valve is very straightforward: it is located at the front of the engine, and you only need to remove the plastic cover to access the fastening pins. Additionally, the manifold has a sort of cap, making dismantling and cleaning very easy to perform. Once the manifold cap and the EGR valve are removed, use brake cleaner to carry out the cleaning.

Installation of Upgraded Intercooler Radiator with Pipes

Lift the vehicle on suitable axle stands, remove the front wheels, and then the front bumper and grille. Proceed to remove the front headlights; drain the coolant, remove the intercooler radiator and the hoses connecting it to the intake system. Position the new intercooler radiator in the grille, temporarily securing it with cable ties, and mark with a marker the part of the metal that needs to be removed to allow the new hoses to pass through. Cut the marked portion of metal and apply a gasket to the edge. Remove the inner cover of the bumper and position it near the radiator to identify any interfering parts to eliminate: again, apply a gasket to the edge of the cut. Create brackets for securing the new radiator and proceed with the installation of the connecting pipes from the radiator to the intake, shaping and connecting them appropriately. Finally, reassemble the bumper, headlights, and grille.
