TOYOTA PREVIA 91-97 REPAIR MANUAL

GENERAL INFORMATION AND MAINTENANCE 1-65

!";' CAUTION

The oil will be hot. Be careful when you remove the plug so that
you don't take a bath in hot gear oil.

5. Allow the oil to drain completely. Clean off the plug and replace it,
   tightening it to 36 ft. Ibs. (49 Nm).


6. Fill the gear housing with gear oil through the filler plug hole as
   detailed previously.


7. The oil level should come right up to the edge of the hole. You can
   stick your finger in to verify this. Watch out for sharp threads.


8. Install the filler plug and gasket, tighten to 29 ft. Ibs. (39 Nm) on
   front housings and 36 ft. Ibs. (49 Nm) on rears. Lower the van, and check
   for leaks. Dispose of the old oil in the proper manner.

Supercharger

FLUID RECOMMENDATIONS

All Previa superchargers use a special supercharger oil (08885-80108)
or equivalent.

LEVEL CHECK

I See Figures 202 and 203

•-When the engine is cold, check the level of the supercharger
dipstick. Inspect the supercharger oil every 30,000 miles (48,000
km).

1. Park the vehicle on a level spot and turn the engine off.


2. On the 4WD models, remove the left front suspension support mem-
   ber and the shift cable stay.


3. Turn the yellow headed supercharger oil level dipstick counterclock-
   wise and pull it out.


4. Wipe the dipstick with a clean rag.


5. Reinsert the dipstick, turn it fully clockwise or the reading will not
   be correct.


6. Remove the dipstick again and look at the oil level on the end.


7. The oil level should be between the L and F marks on the
   dipstick.


8. If the level is low, check for leakage and Air Control Valve (ACV),
   and add oil up to the F mark.


9. Add supercharger oil through the dipstick tube using a vinyl tube
   and syringe. Recheck the oil level.

Syringe

Fig. 203 Using a syringe and vinyl tube, insert the supercharger

oil into the dipstick tube

"•The supercharger could be damaged if it is overfilled or the oil

level is low.

10. On the 4WD models, reinstall the left front suspension support
    member and shift cable assembly.

DRAIN & REFILL

— Inspect the supercharger oil every 30,000 miles (48,000 km).

Toyota does not have an interval to drain and refill the system. If

necessary, remove the magnetic plug under the rear cover and

drain the oil. Insert the plug with gasket and using a syringe and

vinyl tube, fill the system with supercharger oil.

Cooling System

FLUID RECOMMENDATIONS

The correct coolant is any permanent, high quality ethylene glycol

antifreeze mixed in a 50/50 concentration with water. This mixture gives the

best combination of antifreeze and anti-boil characteristics within the engine.

LEVEL CHECK

I See Figure 204

** CAUTION

Always allow the van to sit and cool for an hour or so (longer is

better) before removing the reservoir tank cap. To avoid injury

when working on a warm engine, cover the reservoir tank cap

with a thick cloth and turn it slowly counterclockwise until the

pressure begins to escape. After the pressure is completely

removed, remove the cap. Never remove the cap until the pres-

sure is gone. There should be no excessive rust deposits around

the cap or tank filler hole. The coolant should be free from any

oil. On a COLD engine, place your finger in the coolant and

check for oil or rust deposits.

It's best to check the coolant level when the engine is COLD. The radiator

coolant level should be between the LOW and the FULL lines on the reser-

voir tank when the engine is cold. If low, check for leakage and add coolant

up to the FULL line but do not overfill.

••Check the freeze protection rating of the antifreeze at least once a

year or as necessary with a suitable antifreeze tester.
