1. Having parked the car on a flat horizontal platform, remove the filler cap of the expansion tank. If the engine is hot, wrap a thick cloth around the filler cap and loosen it slowly, gradually depressurizing the system. Watch out for hot steam or coolant vents.
On double overhead cam engines, remove the lower engine skid plate as described in Section 11.
Place a container under the lower radiator hose connection, then loosen the hose clamp and remove the hose from the radiator fitting. If the hose is stuck, turn it on the nozzle to break the connection. Let the coolant drain into a container.
Since the cylinder block does not have a drain plug, and the lower hose can be located above the base of the radiator (on the middle line), it is impossible to completely drain the fluid from the system, therefore it is especially important to fill the system with a mixture with the correct proportion of regulated type antifreeze.
If the coolant drains not because it is time to replace it (it's been less than two years since it was last replaced), then it can be reused (as long as it is clean and transparent).
If the drained coolant is heavily contaminated, the system must be flushed as described in Chapter 4. Since the system cannot be completely drained, it is desirable to flush the system at every fluid change to expel any remaining solids in the fluid from the system.
