Note: If the leak is the reason for removing the radiator, it should be remembered that small leaks can be repaired with sealant.

Removal

• Disconnect the cable from the negative battery terminal.
• Set the temperature control knob in the car to the maximum temperature.
• Drain the coolant from the cooling system.
• Remove the air filter.
• Remove the radiator cap (Fig. 5.26).

Installation

• Installation is carried out in the reverse order of removal, taking into account the following.
• Place the hoses on the fittings so that their ends reach the protrusions on the fittings,
• Secure the hoses with clamps, aligning the marks on the hoses and clamps.
• Fill the cooling system with the required amount of the required coolant.
• Start the engine and let it run until the thermostat valve opens, then stop the engine.
