Adjustment of the tappets on vintage Fiat 500 cars

Model: Fiat 500 Epoca - Years 1957-1975
Part: Valve

In this video we can see how to adjust the tappets of a vintage Fiat 500. The desired adjustment is 0.15 for the intake valves, which is the second one, and 0.20 for the exhaust valve, which is the first one we see: for the second cylinder, we first see the intake valve and then the exhaust valve. The adjustment is done with the two screws located in front. We turn the engine with a 17 key until we bring the second cylinder into phase (closing the exhaust valve and opening the intake valve): this way we can make the adjustment. We will need a feeler gauge with which we will check the play of our tappet, passing the blade with the right thickness under the tappet and then tightening.

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.
