When draining the coolant, keep in mind that cats and dogs are attracted by 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.
3. Drain the cooling system until the coolant is below the upper radiator hose.
4. Remove the upper radiator hose and the connector tube behind the alternator.
5. Remove the bolts securing the heater hose bracket and the transmission dipstick tube.
6. Label and disconnect the spark plug cables from their plugs and wire looms.
