Although the grille on the front of a 1999 Toyota Tacoma is designed to protect the radiator, occasionally a rock will get through and damage the radiator. Or maybe your radiator hasn't been serviced over the years and it's corroded from the inside out. Either way, you must replace the radiator to restore your cooling system to proper operating condition. But first you have to remove the old one. Allow the Tacoma to cool for at least six hours; otherwise you risk burning yourself.
Instructions
- 1
Remove the side marker lenses on the front end next to the headlights, using a Phillips-head screwdriver. Then pull the lenses away from the truck, and twist out the light bulb from the rear.
2Pull the grille toward you to release the clips that hold it in place. Set it in a safe place so it doesn't get damaged. Pop the hood and unbolt the fan shroud from the engine compartment, using a 3/8-inch ratchet and socket.
3Place a drain pan underneath the radiator. Open the radiator cap by hand, then crawl underneath the truck and open the petcock on the radiator. Allow the engine coolant to empty from the radiator.
4Disconnect the upper and lower radiator hoses, using a flat-head screwdriver. Pull the hoses off the radiator, pointing them toward the drain pan to allow excess coolant to drain out. Pull off the overflow hose as well, also using your hands.
5Unbolt the radiator from the core support at the front of the Tacoma where the grille was previously, then lift the radiator out of the engine compartment.
