Here's a general overview of the process; however, this is not a substitute for a proper repair manual. Variations exist across model years.
Tools You'll Likely Need:
* Repair Manual: Absolutely essential.
* Socket Set and Wrenches: Various sizes.
* Screwdrivers: Phillips and flathead.
* Drain Pan: To catch coolant.
* New Radiator: Ensure it's the correct one for your Tempo.
* New Radiator Hoses: Often recommended to replace these while you're at it. Use the correct size and type for your vehicle.
* New Clamps: For the hoses.
* Coolant: The correct type for your Tempo's cooling system. Check your owner's manual.
* Funnel: For adding coolant.
* Gloves: To protect your hands.
* Jack and Jack Stands: For safe working conditions.
General Steps (Consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery terminal. This prevents accidental shorts and electrical hazards.
2. Drain the Coolant: Locate the radiator drain petcock (usually at the bottom of the radiator) and carefully open it into your drain pan. Let the coolant drain completely.
3. Remove the Old Radiator: This involves disconnecting hoses, removing mounting bolts/clips, and potentially disconnecting the transmission cooler lines (if applicable) and the radiator fan. Consult your repair manual for the precise sequence and locations of these components.
4. Clean the Area: Before installing the new radiator, clean the area around the radiator support to remove any debris or old coolant.
5. Install the New Radiator: Carefully position the new radiator into place and secure it using the mounting bolts/clips.
6. Reconnect Hoses and Lines: Attach the new (or cleaned and inspected old) hoses to the radiator, ensuring proper alignment and using new clamps. Reconnect transmission cooler lines (if applicable).
7. Reconnect the Radiator Fan: Make sure the fan is properly secured and functioning correctly.
8. Fill the Cooling System: Carefully add the correct type and amount of coolant (refer to your repair manual). Use a funnel to avoid spills.
9. Bleed the Air from the System: This is critical to prevent overheating. Your repair manual will detail the proper procedure for bleeding the air from the cooling system. Often this involves running the engine with the radiator cap off (carefully, and following manual instructions), allowing air bubbles to escape.
10. Check for Leaks: Once the system is filled and bled, check carefully for any leaks around the hoses, clamps, and radiator.
11. Test Drive: After letting the engine cool slightly, start the engine and let it run for a few minutes. Monitor the temperature gauge and check for leaks. Take a short test drive to ensure proper operation.
12. Top Off Coolant: After the engine has cooled, check the coolant level and top it off as needed.
Again, this is a simplified overview. Use your Ford Tempo's repair manual for detailed, year-specific instructions. If you are not comfortable performing this repair, take your vehicle to a qualified mechanic. Incorrect installation can lead to serious engine damage.
