Remove Radiator Cap (Engine Cold) Step 2 - Once the cap has been turned counter clockwise while pushing downward, lift the cap from the radiator.
Radiator Cap Removed
Remove Lower Shield Mounting Bolts Step 4 - After removing the lower shielding, locate the radiator drain plug and start to loosen.
Locate and Loosen Radiator Drain Plug Step 5 - Once the drain plug is loosened coolant will start draining from the radiator drain. Use a catch basin to collect the coolant to be recycled.
Coolant Draining Step 6 - After the coolant has finished draining, remove the mounting bolts or clips holding the air intake and the plastic fascia over the radiator.
Remove Air Intake Step 7 - Once all of the mounting fasteners are removed, lift the cover from the engine bay. Also move the air intake away from the work area.
Remove Plastic Fascia Cover Step 8 - Next, located and remove coolant reservoir mounting bolts.
Removing Coolant Reservoir Bolts Step 9 - Then, remove the coolant overflow tube from the radiator neck. This hose can become stuck so a twist could be necessary. Once free, remove the coolant reservoir from the engine bay.
Remove Radiator Overflow Hose Step 10 - After the coolant reservoir has been removed, locate and disconnect the cooling fan electrical connector.
Disconnect Radiator Cooling Fan Connector Step 11 - Using a hose clamp removal tool or channel locks loosen the upper radiator hose clamp.
Loosen Upper Radiator Hose Clamp Step 12 - Once the clamp has been loosened, grasp the upper hose and twist to remove.
Remove Upper Radiator Hose Step 13 - Next, remove all cooling fan mounting bolts.
Remove Cooling Fan Mounting Bolts Step 14 - After the cooling fan mounting bolts have been removed, gently lift out the fan and housing.
Removing Cooling Fans Step 15 - Then, using a wrench loosen and remove the automatic transmission cooler lines from the radiator, there should be two of them.
Remove Transmission Cooler Line Step 16 - Once the transmission lines have been removed, locate the radiator mounting bolts and remove.
Remove Radiator Mounting Bolts Step 17 - After the radiator mounting bolts have been removed, move the radiator forward to remove the air conditioner condenser from the radiator. This condenser will remain in the engine bay so vacuum down and recharge is not necessary.
Remove Condenser Mounting Bolts Step 18 - Using a hose clamp removal tool or channel locks loosen and remove the lower radiator hose. A small amount of coolant might leak from the hose, be ready with a fluid catch basin.
Lower Radiator Hose Removed Step 19 - Now that all hoses and mounting bolts and clips have been removed, gently lift the radiator from the engine bay.
Remove Radiator Step 20 - Once the old radiator has been removed, un-box the new radiator and match it up to the old radiator. Look for mounting clips. mounts and transmission lines that might need to be transferred over.
New Radiator Step 21 - After old radiator parts have been transferred over to the new radiator, gently install the new radiator. Be careful not to damage the radiator core while installation is occurring.
Installing New Radiator Step 22 - Once these steps have been completed, reverse the order to reinstall the new radiator. Refill the system with coolant and start the engine, allow the engine to warm completely while adding coolant until the thermostat opens.
Refill Radiator Step 23 - Next, reinstall the radiator cap by pushing down and turning it clockwise until tight, also check the coolant reservoir fluid level. After installing the radiator cap, recheck the system for leaks, also recheck the coolant reservoir after a couple of days of operation. Once driving the vehicle, check the temperature gauge for overheating. Helpful Information A radiator removes heat from the engine through thermal heat exchange using coolant as a conductor and is usually located in the front of the vehicle under the hood. A cooling system consists of many parts including a thermostat, water pump and cooling hoses. A radiator is manufactured with a thin aluminum core coupled with plastic tanks which are prone to coolant leaks. When removing the radiator leaving the cooling fans attached and transferring them onto the new radiator while on the bench could be more efficient. While the radiator is removed use a garden hose to clean the area including the air conditioner condenser. Tools and Supplies Needed
