Repair Instructions

1. Low Coolant Level

Step 1: If the coolant level is low, refill it with the appropriate coolant mixture (50/50 coolant and distilled water).
Step 2: Check for leaks in the system, including hoses, radiator, and water pump.

2. Thermostat Replacement

Step 1: Remove the engine cover (if applicable) and locate the thermostat housing.
Step 2: Drain the coolant from the radiator into a clean container.
Step 3: Disconnect the hoses from the thermostat housing and remove the housing bolts.
Step 4: Replace the old thermostat with a new one, ensuring the gasket is in good condition.
Step 5: Reassemble the housing and reconnect the hoses.
Step 6: Refill the coolant and bleed the system to remove any air pockets.

3. Heater Core Cleaning or Replacement

Step 1: If the heater core is blocked, consider flushing it. Disconnect the inlet and outlet hoses and use a flushing kit to clean.
Step 2: If flushing does not work, the heater core may need to be replaced. This requires removing the dashboard, which is a complex task.
