Toyota RAV4>> Maintenance>> Check of levels of operational liquids>> Engine oil

Fig. 2.1. An arrangement of the index of level of oil (probe) on the engine


Level of engine oil is checked by the index of level of oil (probe) located on the forward party of the engine (fig. 2.1) . The index of level of oil passes through the directing tube in the oil pallet in which oil after lubricant of knots of the engine flows down.
Check oil level before start of the engine or not earlier, than in 5 min. after switching off of the engine. If to make check right after switching off of the engine, a part of oil will remain in the top part of the engine and will not manage to flow down in the pallet therefore the result of measurement will not be correct.
Take the index of level of oil from the directing tube and wipe it with pure rags or a napkin.

Fig. 2.2. Level of oil and an arrangement of tags on the probe of the index of level of oil on cars till 2001: L — minimum; OK — normal; F — maximum


Insert the blank index of level of oil against the stop into the directing tube and take it again. Check the oil level which has to be between tags of L and F on cars till 2001 of release (fig. 2.2) , or between two dredging on release cars since 2001.
If the level of oil is on the lower tag, up to the maximum size it will rise at addition about 1,1 more l of oil.

       PREVENTION
Do not operate the car with the level of engine oil below a tag L or lower dredging on the index of level of oil. In this case because of a lack of lubricant there is an increased wear of details of the engine and there can even be its jamming.

On the contrary, the level of engine oil is higher than a tag of F or the top dredging on the index of level of oil leads to intensive spraying of oil, pollution of spark plugs and leaks through sealing cuffs of a bent shaft.
For a dolivka of oil uncover an oil-filling mouth, located on a cover of a head of the block of cylinders. Add necessary amount of oil and establish a cover into place.
Start the engine and let's it work several minutes. Check whether there is no leak of oil around the filter and a stopper of a drain opening on the pallet.
Stop the engine and wait several minutes that oil flew down in the pallet. Check the level of oil and add if it is necessary. Check reliability of an inhaling of a stopper.
Check of level of engine oil — an important element of prevention of the engine. Bystry falling of level of oil indicates a leak through sealing cuffs of a bent shaft, laying of the oil pallet, wear of piston rings or the directing plugs of valves.
If color of engine oil changed to dairy or at it there are water drops, so laying of a head of the block of cylinders is punched, or in a head or the block of cylinders the crack was formed. It is necessary to check immediately a condition of the engine and to eliminate malfunction.
Also when checking level check a condition of oil.

       PREVENTION
For quality check of oil before rubbing of the index of level of oil run over it a finger. If on a finger there were small firm particles, immediately replace engine oil and an oil filter.
