How to Replace a Radiator in a 2000 Chrysler LHS

104 55

    Removing the Radiator

    • 1). Detach the negative (black) radiator cable with a wrench.

    • 2). Slide a large drain pan under the radiator and open the radiator drain plug. Loosen the radiator cap and drain the coolant completely. Close the drain plug and remove the drain pan. Store the coolant in a sealed container for later recycling.

    • 3). Unfasten the radiator upper cross-member with a ratchet and socket and remove the cross-member. Shift the transmission into neutral and block the rear wheels with chocks.

    • 4). Raise the front of the Chrysler with a floor jack and support it on two jack stands.

    • 5). Squeeze the clamp tabs that secure the upper and lower radiator hoses to their fittings with a pair of rib joint pliers and slide the clamps towards the engine. Pull the upper and lower hoses off the radiator fittings.

    • 6). Place a small drain pan under the cooler lines attached to the radiator and detach the transmission cooler lines from the radiator with a line wrench. Immediately cover the line openings with clean plastic sheets and rubber bands to prevent contamination of the system.

    • 7). Unplug the cooling fan electrical connector and unfasten the fan assembly mounting bolts with a ratchet and socket. Pull the fan assembly off the engine compartment.

    • 8). Unfasten the condenser-to-radiator mounting bolts through the front of the vehicle with a ratchet, ratchet extension and socket. Check around the radiator for any brackets or bolts that might be holding the radiator in place and remove them with the ratchet and socket.

    • 9). Lift the condenser a few inches to disengage the upper mounting clips and let the condenser rest on the lower radiator cross-member. Carefully lift the radiator out of the engine compartment.

    Installing the New Radiator

    • 1). Transfer the rubber isolators at the bottom of the old radiator to the new radiator with the ratchet and socket then position the new radiator in place in the engine compartment.

    • 2). Lift the condenser just enough to engage the condenser upper mounting clips and fasten the condenser-to-radiator mounting bolts through the front of the vehicle with the ratchet, ratchet extension and socket.

    • 3). Replace the fan assembly with the ratchet and socket, plug in the fan's electrical connector and reattach the cooler lines to the radiator with the line wrench.

    • 4). Reconnect the upper and lower hoses to the radiator fittings. Secure the hoses to the radiator fittings with the clamps and the rib joint pliers.

    • 5). Lower the Chrysler off the jack stands, remove the blocks from the rear wheels and reinstall the radiator upper cross-member with the ratchet and socket.

    • 6). Locate the coolant bleeder valve on the lower center part of the lower intake manifold. This is a small valve with a molded nut around its body. Attach a 48-inch long, clear vinyl hose with an inside diameter of .250-inch to the bleeder valve. Slide the drain pan under the vehicle, point the other end of the hose into the pan and loosen the bleeder valve with an open-end wrench.

    • 7). Remove the coolant reservoir cap and install the special funnel (tool #8195) on the reservoir opening. Use the clip on the tool to pinch the hose that connects the two chambers of the reservoir. This tool will remove most of the air as you pour the coolant into the reservoir.

    • 8). Pour a 50/50 mixture of Mopar antifreeze coolant (five-year/100,000 mile formula) and distilled water into the larger section of the funnel. Use the same amount of coolant you removed from the old radiator plus an extra 1/2-gallon. Fill the system until the coolant reaches the top of the special funnel. Remove the clip from the hose to allow the coolant in the funnel to fill the adjacent chamber of the reservoir. Remove the special funnel and tighten the reservoir cap.

    • 9). Attach the negative (black) radiator cable with the wrench, detach the hose from the bleeder valve and tighten the valve with the wrench. Start the engine and let it idle until the cooling fan comes on. Turn off the engine and let it cool down completely.

      Add coolant to the reservoir to bring the level between the "Min" and "Max" marks if necessary. If there is coolant in the adjacent section of the reservoir after the engine has warmed and cooled several times throughout the week, disconnect the reservoir hose from the filler neck and drain the coolant in the adjacent section of the reservoir into a clean, sealable container. Reconnect the hose to the reservoir filler neck.
