REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
- Properly drain the cooling system into a suitable container.
When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
- Disconnect the upper, lower and overflow hoses from the radiator.
- If equipped with an automatic transmission, disconnect the transmission oil cooler inlet and outlet lines from the radiator. Plug the fittings/lines to prevent contamination of the transmission oil cooling system.
- Depending on the model, remove the two top mounting bolts and remove the radiator and shroud assembly, remove the shroud mounting bolts and position the shroud out of the way, or remove the side mounting bolts. If the A/C condenser is attached to the radiator, remove the retaining bolts and position the condenser out of the way. DO NOT disconnect the refrigerant lines.
- If equipped with an SC engine, remove the two bolts retaining the top of the air duct to the charge air cooler.
- Unfasten the radiator attaching bolts or top brackets, then lift out the radiator.
- If a new radiator is to be installed, transfer the petcock from the old radiator to the new one. If equipped with an automatic transmission, transfer the oil cooler line intermediate fittings to the new radiator, using Pipe Sealant with Teflon®.
- Position the radiator and install the upper brackets, if equipped and tighten the mounting bolts securely.
- If equipped with an SC engine, cut the retaining strap from the charge air cooler air duct. The duct should spring out from the radiator support assembly. Lift the top of the duct and insert the tabs into the bottom of the duct into the clips at the bottom of the charge air cooler. Install the two bolts that retaining the top of the duct to the charger air cooler.
- On cars equipped with automatic transmissions, unplug and connect the oil cooler lines using a backup wrench. If equipped, tighten the tube nut on the line to 18-21 ft. lbs. (24.4-28.5 Nm).
- Install the cooling fan motor, blade and/or shroud as necessary.
Make sure the clamps are beyond the bead and place in the center of the clamping surface of the connections. New screw-type hose clamps must be installed inside the hose alignment marks.
- Connect the radiator upper and lower and the overflow hoses. Position the clamps at least 2 in. (50mm) from each end of the hose and slide the hose on the connections. Tighten the clamps to 20-30 inch lbs. (2.2-3.4 Nm).
- Close the radiator petcock. Fill and bleed the cooling system with a 50/50 mix of the proper type and quantity of coolant and clean water.
- Start the engine and bring it to operating temperature. Check for leaks.
- On cars equipped with automatic transmissions, check the cooler lines for leaks and interference. Check the transmission fluid level.
- Turn the engine off, then check the radiator and radiator coolant recovery reservoir fluid levels. Add if necessary.
