A Warning: Wait until the engine is cold before starting this procedure.

1 The coolant antifreeze strength can be checked using a proprietary tester obtained from a car accessory shop. One type of tester acts similar to a battery hydrometer and has five small plastic balls within a clear tube - the coolant strength is determined by the number of balls floating in the coolant.

2 To use the tester, lift the cap from the coolant expansion tank and draw out some of the coolant. Hold the tester vertical and check the number of balls floating. After making the test disperse the coolant into the expansion tank and refit the cap.

1 On 4A-FE and 7A-FE engines, two or three drivebelts are fitted. The main drivebelt drives the water pump and alternator from the crankshaft pulley. Where air conditioning is fitted, the compressor is driven by a separate drivebelt from the crankshaft pulley. Where power steering is fitted, a secondary drivebelt drives the pump from the water pump pulley.

2 On 3S-FE and 3S-GE engines, two drivebelts are fitted. The main drivebelt drives the alternator from the crankshaft pulley (see illustration). On models with air conditioning the main drivebelt is longer and drives the air conditioning compressor in addition to the alternator. The power steering pump is driven by a separate drivebelt from the crankshaft pulley.

Checking the condition of the auxiliary drivebelts

3 For improved access to the auxiliary drivebelt on the right-hand side of the engine, remove the washer fluid reservoir as described in Chapter 12. If required the vehicle may be jacked up and supported on axle stands (see Jacking and Vehicle Support) and the right-hand roadwheel removed.

4 Using a socket and extension bar fitted to the crankshaft pulley bolt, rotate the crankshaft so that the entire length of each drivebelt can be examined. Examine the drivebelts for cracks, splitting, fraying or damage. Check also for signs of glazing (shiny patches) and for separation of the belt plies. Renew the belt if worn or damaged.
