换Coolant之法

[Youlong]

由于Coolant提前结冰，准备根据月下独酌先生的意见换掉。可去问了一下Canadian Tire, 需$79.99+Tax。感觉挺贵，能自己干吗，或哪有便宜地方？谢谢！

找到radiator下面的塞子, 拿个盆在下面接着, 拧开放掉旧液, 拧上塞子加新液就行了.

如果用花园水龙把散热器里面冲冲就更好了.

够贵的啊！！

没那么简单

这样换下来发动机里面一半儿空气，更伤车

冬天还是不要自己换了

干吗不找黑哥啊


你就是自己换下来也得40－50。不值得

高压盖、排气筏也要打开，排气很重要。换好后，先不要盖，发动车等几十秒，看液位不够还要补满，最后才加盖。

俺这样换过好几次, 没问题.

coolant只要一桶, $8.

不知道你自己换怎么能换出$40-50来, 就算你用蒸馏水掺, 就算你用coolant把里面再洗两三遍, 也超不过$20.

假如你怕里面有空气, 那可以用根管子, 从下面排水阀往里灌, 看到上面压力阀出水停止. 用花园水龙洗就是那么洗的.

你这种换法不能排出block 最顶端的空气。正确方法是添水的时候把block上一个特殊的阀门打开泄气。

换coolant同时应该换pressure cap.

coolant 8, pure water +5 + pressure cap 10 = 23 + tax...

要是买好点儿的coolant呢就价钱高了。这玩意还是不要省钱好

有DIY经验的可以把thermostat也换了

压力阀那个盖如果没破, 不用换的. 因为它是在最顶上, 即使有少量水出来很快就干掉把可能的微小缝隙都堵住.

错

cooling system是一直underpressure的，Cooling cap里有个弹簧和seal, coolant会让seal老化，弹簧也会失去弹力，cooling效率急降

If it's not broken, don't fix it.

你换机油的时候是不是也要换放油阀门? 那也是用橡胶垫圈的, 温度更高.

It is not difficult to bleed the air out.
Method 1, using the air bleeder bolt:
1. Install radiator cap
2. Fill reserve tank to the "full" level with coolant and put the cap on
3. Run the engine.Bleed air from the system using the air bleeder bolt in the casting (it is a little screw with a hole on top)
Note: Use socket wrench or ring wrench to loose the screw until no more bubble come out. DO NOT USE ADJUSTABLE WRENCH, it will spoil the bolt.

Method 2, running the engine and let the air out through the cap opening:
1. Start engine (radiator cap off) and run until no more air bubbles can be seen. Tap radiator hoses to force any remaining air bubbles to the top. Stop engine, add coolant to top of filler neck. Install cap
2. Remove reserve tank cap again and fill tank to the 'full' level. reinstall cap.
Finally, Ride. Check the reservoir level after the engine has cooled to be sure the coolant level is proper. Top off to the 'full' mark if its low

得了，你对，我不说啥了

那么你的意思是不是timing belt应该断了之后再换？

 

[Kent以东首帅哥]

Yeap, that's exactly what I do. I didn't have any timing belt brokeage in last 120k kms though.

 

[吾言]

I think most of us are very interested to know how you gonna change your time belt after it breaks.

If that does happen, I will get myself another $1000 car.
Depending on your car, it's always troublesome to replace a timing belt. Basically you will have to dissemble a large portion of you engine to remove the $20 belt.
