OIL LEVEL CHECK
Every time you stop for fuel, check the engine oil as follows:
- Park the truck on level ground.
- When checking the oil level it is best for the engine to be at operating temperature, although checking the oil immediately after a stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the oil pan (crankcase).
- Open the hood and locate the dipstick. Pull the dipstick from its tube, wipe it clean and reinsert it.
- Pull the dipstick out again and, holding it horizontally, read the oil level. The oil should be between the F and L marks on the dipstick. If the oil is below the L mark, add oil of the proper viscosity through the capped opening on the top of the cylinder head cover.
- Reinsert the dipstick and check the oil level again after adding any oil. Be careful NOT to overfill the crankcase. Approximately one quart of oil will raise the level from the L to the F . Excess oil will generally be consumed at an accelerated rate as well as hampering engine operation.
OIL AND FILTER CHANGE
The oil and filter should be changed every 7,500 miles (12,000 km). The mileage figures given are the Toyota recommended intervals assuming normal driving and conditions. Normal driving requires that the vehicle be driven far enough to warm up the oil; usually this is about 10 miles (16 km) or so. If your everyday use is shorter than this (one way), your use qualifies as severe duty.
Severe duty includes dusty, polluted or off-road conditions, as well as stop-and-go short haul uses. Regularly towing a trailer also puts the truck in this category, as does constant operation with a near capacity load. Change the oil and filter at 1 / 2 the normal interval. Half of 7,500 equals 3,250 miles (5,229 km); round it down to the easily remembered 3,000 mile (5,000 km) interval. For some owners that may be once a month; for others, it may be six months.
The oil drain plug is located on the bottom, rear of the oil pan (bottom of the engine, underneath the truck). The oil filter is located on the side of the engine. One some vehicles, the oil drain plug and the filter may be located behind access panels in the engine under covers.
Always drain the oil after the engine has been running long enough to bring it to normal operating temperature. Hot oil will flow easier and more contaminants will be removed along with the oil than if it were drained cold. To change the oil and filter:
- Run the engine until it reaches normal operating temperature. Shut down the engine.
- Raise and safely support the front of the truck on safety stands.
- Slide a drain pan of at least eight quarts capacity under the oil pan.
- Loosen the drain plug with a wrench. Turn the plug out by hand. By keeping an inward pressure on the plug as you unscrew it, oil won't escape past the threads and you can remove it without being burned by hot oil.
- Allow the oil to drain completely and then install the drain plug. Do NOT overtighten the plug, or you'll be buying a new pan or a replacement plug for stripped threads.
- Using a filter wrench, remove the oil filter. Keep in mind that it's holding about one quart of dirty, hot oil. Make certain the old gasket comes off with the filter and is not stuck to the block.
- Empty the old filter into the drain pan and dispose of the filter.
- Using a clean rag, wipe off the filter adapter on the engine block. Be sure that the rag doesn't leave any lint that could clog an oil passage.
- Coat the rubber gasket on the filter with fresh oil. The reason for this is that the rubber will react with the oil and swell a small amount, making a good, tight seal without having to tighten the filter excessively. Spin it onto the engine by hand; when the gasket touches the adapter surface give it another 1 / 23 / 4 turn. No more, or you'll crush the gasket and it will leak.
- Refill the engine with the correct amount of fresh oil. See the "Capacities" chart.
- Check the oil level on the dipstick. It is normal for the level to be a bit above the full mark. Start the engine and allow it to idle for a few minutes.
- Shut OFF the engine, allow the oil to drain for a minute, and check the oil level. Check around the filter and drain plug for any leaks, and correct as necessary.
