最近根据经修订的服务维修研究，最近更新有关6.6L柴油发动机（RPO LML）和1.4L和1.5L和1.5L汽油发动机（RPO LE2，LFV）的GM服务信息。（图14）由于定期更新服务信息，重要的是要始终查看维修的服务过程，以便确认遵循最新过程。

作为开发创新方法的倡议的一部分，GM持续审查服务程序，以确保每一步都提供安全，有效和有效的维修。最新更新的重点是减少需要在车辆上完成的程序删除发动机的程序。新程序避免将发动机拉动完成维修，并且在许多情况下，消除了撤离的需要，恢复和再充电空调系统。该更改也导致减少完成修复所需的强制替换螺栓和垫圈的数量。
基于修订程序更改的一些主要修复操作包括：
2015-2016 6.6L柴油发动机（RPO LML）
- 缸盖置换右/左
- Head Gasket Replacement Right/Left/Both
- 涡轮增压器更换
- 燃油喷射泵更换
- 其他程序与上述删除相关
2016-2019 Cruze 1.4L发动机（RPO LE2）和Malibu 1.5L发动机（RPO LFV）
- 活塞，连杆和轴承更换
- Piston and Ring Replacement
- 气缸盖更换
- Cylinder Head Gasket Replacement
Check the appropriate Service Information for these updated service procedures.

Its only possible with the engine on a stand ! and I think it say’s engine out of vehicle repair
Thank you for your feedback. You are correct that the Doc ID for Cylinder Head Replace – Left Side is the same between the 2015/2016 and the 2014 and prior MY vehicles. Where the changes occur are in the links to sub procedures within the head replace procedure that are different between the two model years for now. As an example, as you follow the cylinder head replace procedure, the first link is “Intake Manifold Replacement – Left Side”, which you will also find the same Doc ID for this procedure between model years. But from there, as you go into Turbocharger replacement or Fuel Injection Pump replacement, there are unique Doc ID’s with unique procedures. This is just a couple of link examples. There were a number of sub linked procedures that were updated that all feed up to a more efficient cylinder head replacement.
因此，2015年和之前，它使用SI 2413099中的完全相同的文档ID进行左侧气缸盖垫片，保修劳动时间为30.9小时，额外发布的时间和2015年，并为10.4hrs为10.4hrs？
I would like to see someone come here and do it in the truck in 10.4hrs – I call BS
良好的工作通用汽车驾驶更多技术人员。服用，拿走......
2015-2016 6.6L柴油发动机（RPO LML）的哪一部分◾Cylinder Regent右/左/左/左右变化，以便省短。它看起来和我一样吗？
在SI中概述的服务过程之后，我看不出如何在此时间内完成DURAMAX头部垫圈。它只是不可能将那么多的东西分开，清洁所有东西，并重新组装许多组件在这一段时间内。在进行计算时，您忘记添加涡轮涡轮或喷射泵的时间或其他东西。
The new service procedures that were implemented in the Service Information that resulted in revised labor time allowances were completely new procedures over what was previously published. This was not a study of older procedures, but rather a completely new procedure that was studied following the standard study process of no power tools, following SI step by step and providing a 21% mark-up at the end of the study.
I think it’s unacceptable to reduce labor times due to GM certified techs beating the flat rate time. Moreover, if you do a 6.6 headgasket job twice a year, it’s going to take you 30 plus hours. GM does not have quality in mind if they want to rush their repair jobs. Reducing labor times is GM’s way to keep more money in their pocket, and frustrating the techs. You should revisit the reduction in flat rate hours, and restore it to the previous.
