Removal and Replacement of the Intake Manifold

Model: Mazda Mx 5 NB, MK 2 - Years 1998-2005
Part: Cylinder head

This tutorial explains how to remove and replace the intake manifold on a Mazda MX-5. Open the bonnet and disconnect the negative terminal of the battery. Remove the intake pipe by loosening the clips that hold it in place and unscrewing the bolts with a 10 mm socket from both sides. Using your fingers, disconnect the electrical connector near the inlet of the pipe. Now you need to remove the throttle cable. Loosen the adjuster and detach the cable. Remove the rubber gasket from the inlet and proceed to remove the bolts securing the manifold. The next part of the video introduces the following phase, which will explain in another video how to replace the manifold.

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.
