Steps:
1. Remove the engine bottom cover: Use a wrench to remove the bolts securing the engine bottom cover. Remove the cover to access the radiator.
2. Drain transmission fluid: Place a drain pan under the radiator and disconnect the transmission fluid cooling lines from the radiator. The liquid will drain into the pan.
3. Disconnect the coolant lines: Use a wrench to remove the bolts holding the coolant lines to the radiator. Carefully slide the cooling lines away from the radiator.
4. Remove the mounting bolts: Use a wrench or hex key to remove the bolts holding the radiator to the vehicle frame.
5. Remove the old radiator: Gently pull the old radiator forward to remove it from its place. Drain the remaining transmission fluid.
6. Install the new radiator: Insert the new radiator into the mounting location. Tighten the mounting bolts with a wrench or hex key.
7. Connect the coolant lines: Place the coolant lines onto the radiator and tighten the bolts.
8. Fill with transmission fluid: Place a funnel in the transmission filler hole. Pour new transmission fluid into the funnel and top up to the required level.
9. Install the radiator gasket: Install a new gasket onto the radiator and press it against the coolant line flange.
10. Connect the engine bottom cover: Reinstall the engine bottom cover and tighten the mounting bolts.
11. Connect the negative terminal of the battery: Connect the negative terminal of the battery to complete the process.
12. Check the transmission fluid level: Run the engine at idle speed and check the transmission fluid level using the dipstick. Add fluid if necessary.
Note: On some vehicles, it may be necessary to remove the front end of the vehicle to gain access to the transmission cooler. Consult your specific vehicle’s service manual for details.
