ENGINE OIL


-How often?

Most engine manufacturers (including Toyota) recommend an oil change every 100-200 hours, 3000-5000 miles or every 6 months. Most engine oils only have a shelf life of one year, filters when saturated only have a 6 month install life.

-What to use?

This is where personal choice and a lot of brand loyalty comes in so make your own decision here, as long as it meets 'API SC or greater'. The current standard is SL, you will find this in most all brands/blends so its hard to go wrong here.

-What is needed?

  • Engine Oil (4qts)
  • 4AG Engine oil filter
  • 12mm socket/wrench
  • oil catch (bucket/pan any liquid container)
  • Latex gloves
  • Funnel


Cooldown/WarmUp

- If the car has not been run for quite some time, take a moment to allow the engine to run for a couple minutes. This will allow for the oil to circulate, warm up and capture any settled debris. If the car has recently been run, allow the oil to cool for at least half an hour to prevent risk of burns due to hot oil coming in contact with ones hands.

Preparation

- Begin by jacking up the front of the car from the cross-member. Secure the car with jack-stands. Two square frame rales run the length of the car, place them evenly as possible on both sides, place the stand on that location.

Draining

- Remove the oil cap from the top of the engines valve cover. Return to the underside of the car and locate the drain plug at the bottom of the oil pan. Once located, position the oil catch below the outlet, unbolt and allow the oil to drain.

While the oil drains, take a moment to entirely clean the drain plug. Once the oil has fully drained and the plug is cleaned, return the plug and tighten.

Filter Removal

- Locate the oil filter on the exhaust side of the engine block. Remove it by spinning counter-clockwise. It is recommended that the oil catch be placed under the oil filter to catch any oil that my leak from the filter upon removal. Upon removal, allow filter to drain before discarding.

Filter Replace

- Remove new filter from its packaging and determine if the O-Ring has been pre-lubed. If not, take a small dab of oil and coat the ring. This will keep the gasket from cracking and allow for easy removal come next oil change.

Replace the filter by spinning it on clockwise. Turn untill you meet resistance then turn it once more more or as packaging recommends.

Refill


- Once you are done with replacing the filter its time to re-fill the engine with oil. Pour the oil in through the oil cap we removed before starting. How much you need will depend on your method of install, generally;

--- w/o filter change 3.4l (3.6qts)
--- w/ filter change 3.7l (3.9qts)
--- Dry/new 4.1l (4.3qts)

Wrap Up

- Once you are done, replace the cap and inspect your work, double check that everything is secure and installed properly. Once done, lower the car and check the oil level with the dipstick. Once all checks out, start the engine and allow it to run for a while, check to be sure that the engine doesn't leak any oil.
Now your engine has fresh oil and you're on your way!

TRANSMISSION OIL


-How often?

Most manufacturers (including Toyota) recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy use, manufacturers suggest changing every 15,000 miles. If you are involved in any form of motor sports, 10,000-15,000 is about how often you should be changing.

-What to use?

This is where personal choice and a lot of brand loyalty comes in so make your own decision here, as long as its 75w-90 GL4 or greater.

-What is needed?

  • Gear Oil: 75w-90 (GL5) (1.8qts)
  • 12mm socket/wrench
  • 10mm socket
  • oil catch (bucket/pan any liquid container)


Cooldown/WarmUp

- If the car has not been run for quite some time, take a moment and drive for a couple minutes. This will allow for the oil to circulate, warm up and capture any settled debris. If the car has recently been run, allow the oil to cool for at least half an hour to prevent risk of burns due to hot oil coming in contact with ones hands.
Now that our oil is ready to be drained, turn off the car and jack up the front of the car from the cross-member. Safety first! Secure the car with jack-stands. There are two square runners that go down the length of the car, place the stand on that location. Its always a good safety precaution to leave the jack under the car holding gently onto the car in case a jack stand fails.
Now jack up the rear too by the rear end and place jack stands on the ends of the axle too

Draining

- Once the car is jacked up and stable, start the oil draining process, go under the car and locate the bolt on the transmission to allow it to drain. The drain plug is the lower bolt, the upper is the check plug. Use a 19mm socket or wrench and loosen and remove.

Make sure you have your oil catch ready. While waiting for the oil to drain it’s always a good idea to clean the drain plug thoroughly.

Interior

- Once the transmission is draining, go ahead and begin to remove the shifter, first you will need to take out the center console and then the second part where the shift boot
is located. Once you have removed all of these you can unbolt the shift boot itself using a 10mm socket and a 3inch or greater extension. Once removed, you will need to remove the shifter from the transmission itself, do this using a 14mm socket and the same extension.

Refilling

- By the time we are all done with this, our oil should be all drained out, so return the plug that you removed back in and reinstall it. Now locate the 2nd plug on the side of the transmission, its located directly above the drain plug. This is the fill limit check; once oil begins to flow through here we know we are at the correct level.

Refilling


- Now that we have our check removed and the drain plug back in, its time to fill through the open shifter inside the car. Begin to pour 1.7liters (1.8 quarts) of fluid into the transmission, once you get close be sure to randomly check to see if you are at the correct level yet by checking for overflow from the open plug. Once you see it over flow, stop pouring.
Return the check plug and bolt back into the transmission. Then reinstall the shifter, shifter boot and center console in the reverse order.

Cooldown/WarmUp

- Once you are done, inspect your work, double check that everything is secure and installed properly. Once done, lower the car and run the car. Check to see if shifting is easy and the shifter doesn’t have trouble cycling through the gears. Allow the car to run for a while, check to be sure that no oil is leaking. Now you are all done and your transmission is ready for solid shifts and cool, lubricated running!

REAR AXLE/LSD OIL


-How often?

Most manufactures recommend that you change your differential oil every 24months/30,000 miles.
If you are consistently doing a lot of hard driving, it may be beneficial to replace more often.

-What to use?

This is where personal choice and a lot of brand loyalty comes in so make your own decision here, as long as its 80w-90 GL5.
If you have installed an aftermarket LSD it is suggested that you use the aftermarket brands oil to ensure compatibility, safety and possible warranty reasons.

-What is needed?

  • Gear Oil: 75-80w-90 (GL5) (1.8qts)
  • 24mm socket/wrench
  • Liquid Pump
  • Oil Catch (bucket/pan any liquid container)


Preperation

- Jack up the rear of the car from the center of the axle (pumpkin). Secure the car with jack-stands. Place the jack stands on the axle ends and rest the car on the jack stands.

Draining

- The axle has two plugs on it, the upper is a check/fill plug and the lower is a drain. Begin by opening the two plugs and allowing the oil to drain. While the oil is draining, be sure to clean both plugs thoroughly. The lower plug has a magnet in the center and collects all metal fragments, be sure to remove any collected metals.

Refilling

- After all liquid is drained, the lower plug will need to be replaced. This is where the liquid pump will be used. (Depending on suspension, install procedure, product packaging, you may be able to bypass the need for the pump. For ease of replacement we will use the pump) The pump works simply by placing the pump assy. into the product and placing the other end into the fill plug. To fill, simply pump until fluid begins to overflow from the check/fill plug. Reinstall plug and cleanup.

Preperation

- Once you are done, inspect work, double check that everything is secure and installed properly. Once done, lower the car and run the car. Check to be sure that no oil is leaking.
