engine oil changing

1. oil pan drain plug located: Back side of oil pan towards the crankshaft pulley end.
2. oil filter located? Opposite side from the plug near the crankshaft pulley.
check list: plug size 5/8 best, 16 ok; oil 5-20w better, or 5-30, oil filter wrench;
paper, napkin, glove; 2 basons, seal bag, plastic bag, adhesive tape; light, curtain cloth; funnel; bucket, dustbin;
-------
0. dress cloas so that arm can release and go out
0.5 bag paste to bason
1. drive to heat the car, stop in a plain, dark place.
2. Close car and lift Handbrake.
3. take: cloth, 5/8 wrench, bar, bason, light, glove, paper
4. dress glove -> put cloth -> lie down so that head in the middle -> 5/8 wrench to plug -> strike wrench with bar quickly
-> put bason under and release plug with hand -> take the plug carefully, watch the seal, don't put it in the bason -> wipe with papers
-> put plug in a safe place and remember it.
5. open the cap of the car and open the oil cap, 测油棒提起。
6. take all things back accept cloth.
7. have a rest for have an hour.
8. take: 5/8 wrench, oil filter wrench; light, glove, paper
9. learn how to use oil filter wrench;
10. locate oil filter -> use wrench to let it move -> move bason under -> move filter and put it into bason
11. unware glove and use hand
12. 新油润一下密封胶圈以利密封。don't put too much oil to filter, otherwise, as oil spill out, it will be too slipy to rotate.
13. locate the nut -> keep trying to rotate -> fix it.
14. rotate oil plug, don't put basin on the right of hand, because the hand with big strengthen may strike it.
15. see how much oil in bason and judge how much oil to use.
16. lift the funnel a little will speed up -> drop in about 3.5 Qt -> see the oil level in stick, -> add more or not.
17. put a plastic bag into bucket -> use adhesive tape to seal oil and put it in the bucket.


The first number (such as 5W) indicates the low-temperature (Winter) viscosity.  Viscosity simply is a measure of an oil’s ability to flow and protect at certain temperatures.  The lower the number, the easier the oil will flow (and protect) in cold weather when starting your car.  The second number (such as 30, in 5W-30), indicates the thickness of the oil at operating (high) temperatures.

1． 开车先兜两圈，让温度表上升到工作温度，停车入位，息火，开始铺棉垫子或报纸于
前轮前，搞清楚泄油螺栓的具体位置，于同侧支起双千斤顶 (绝非杞人忧天，因为天的确
会塌下来) ，不用支的太高。收集器推车底下去备用。
2． 掀开动力仓盖，把引擎顶部的写有ENGINE OIL 字样的齿轮形盖子拧下来，通气的干
活。然后躺车底下去，用死外六方扳手或梅花扳手 (12-POINTS) 拧下泄油栓，有时要用
吃奶的劲儿。我换的时候我没买死外六方，梅花的又不够大，棘轮扳手加3/4套筒我认为
难以承受这么大的扭力，而且力臂也不够，我就用的200毫米的活扳子，那叫一个费劲，
结果两败俱伤，六角磨损了，扳手的边缘居然成犬牙状--弄出NICK来了。所以我怀疑哪个
泄油拴是高碳钢的。长此以往，次数不用多，4-5回我估计六角就磨圆了 (ROUND OFF) ，
您要是学我，嘿，到时候银子就又能找到归宿了。所以啊，今天我去买了一个大十字的四
头死外六方扳手，我戏称其为飞去来扳手。这东东在卸轮子时也用的上。啊，净顾跟您说
话了，油都滴滴达达往下淌了，小心烫手，一把把收集器拽过来接着，BY THE WAY，您开
始工作的时候没忘带手套吧，即便是男同志也要对得起自己的手啊。
3． 这油一开始是滴达，整个螺栓下来后就沽沽的了，看着废流出来心情激动，当年大庆
第一口井出油时工人们的心情略微有所体会。根据油的颜色性状您可以揣测此次换油时机
和引擎内部情况。有的车放出的油还挺清，有的就跟石油没两样。估摸着有十多分钟吧，
放差不多了，把泄油螺栓拧死，哪个密封胶垫您可别忘了给装上，要是发现破损了就换他
一个。
4． 啊，终于可以从不见天日的车底下钻出来了，前提是你的机油滤器在引擎正面，LOCA
TE机油滤器，周围用破布妈一下，把特制扳手套脑瓜顶上，用3/8棘轮扳手给丫拧下来，
必要是用加长臂，运作空间应该没问题，起码TOYOTA这点作的就很好。注意滤器里的残油
，防烫为主。滤器放到回收器上DRAIN干净。
5． 拿出新滤器，用新油润一下密封胶圈以利密封。确信旧胶圈没有沾在底座上，将新滤
器用手拧紧，在用棘轮扳手额外拧3/4圈。 (又有1/2圈说，看你如何定义HAND-TIGHT了)
6． 然后就是激动人心的REFILL了，提起新油从顶上的机油盖古达古达灌进去，灌多少主
观看手册客观看油尺，我的佳美是4升，别的车只要不是坦克装甲车辆差不多也3，4，5升
左右吧。反正跟排量有正相关。(我给同学的TERCEL换就少用了将近一升) 。
7． 灌入标量后稍歇片刻，喘口气儿，让后抽油尺，油平在L到F之间偏F就行了，不行再
加，然后拧紧机油盖，HAND-TIGHT。关HOOD，发动，跑两圈回来，息火，少倾，拔油尺，
擦干净，插入，拔之DOUBLE CHECK。没问题后，查滤器处，泄油拴处有无漏油。 (注意此
刻少许的滴达很可能是灌油时不小心SPILL的)。
8． 翌日，再查一下这两处，及停车位的地面，地上有油的话要确定确实是你自己的油。
别笑，有这样的先例啊。
9． 废油DISCARD掉。
