Installation Instructions for Thermostat Kit 74–85 HP Version – FIAT 124 Spider

Around 1974, the cooling system of the FIAT 124 Spider was modified: a bypass system was introduced, and the thermostat was relocated from the cylinder head to a 3-way housing.
With this thermostat kit, we reverse that change: the thermostat is once again mounted directly in the cylinder head.

Installation Steps:

  1. Preparing the Gasket:
    Shape the gasket slightly conically as shown in Image 3, so that the radius at the bottom becomes a little smaller. This makes it easier to insert the gasket into the cylinder head.

  2. Installing the Thermostat:
    Make sure that the longer part of the thermostat disappears completely into the cylinder head.

  3. Mounting the Thermostat Housing:
    Attach the thermostat housing and reconnect the cooling system by installing the water T-piece.

  4. Installing the 3-Way Housing:
    The 3-way housing can be installed according to your preference.
    Since this housing no longer contains a thermostat insert, the installation direction is not critical.
