MACS Service Reports - 2015 - MAR7

Figure 9: Mastering Hybrid HVAC Systems is one of several A/C topics available from AVI.

RTI / Mahle Compressor Oil Chart
One honorable mention of a simple A/C related
website I've used for years is the compressor oil
chart from RTI. This downloadable PDF chart shows
compressor illustrations and model numbers, along
with OEM recommended oils and oil balancing procedures. It's a very quick, two page reference document that's very easy to use compared to the "Easter egg hunt" that some full ESI websites make of
finding simple things sometimes.

A variety of discussion groups on iATN include
such topics as an HVAC discussion group, a forum
for educators and a shop management discussion
group.
Other resources include:
1. Lambda Calculator (plug in your gas analyzer
readings to get the Lambda number)
2. OBD - II DTC Look Up
3. Service Bulletin Search
4. Trade Publications
5. Fellow iATN Member Search

international Automotive Technicians Network - iATN
www.iatn.net has over 75,000 members from 157
countries sharing 1.7 million years of auto repair
experience. It was the first and is the largest online technician network. But even though iATN has
been around since 1995, I'm still amazed at how
many professional technicians are still unaware of
this useful web based technical resource. Members
have access to technical assistance from the iATN
database, thousands upon thousands of image files
(scope and scan tool captures), OEM training information (including tons of free factory Ford, GM
and Toyota info), as well as discussion databases
archiving millions of messages and records shared
between service professionals. Members must be

When a member submits a post for technical help,
he or she is responsible for updating the post with
further findings and closing the post with a detailed
summary of what fixed the vehicle. You'll receive email reminders to update / close your open posts.
Members are rated on timely closings of technical
posts in order to keep the network relevant for other technicians wishing to search for closed cases to
help them with difficult to solve vehicle problems.

full time automotive service professionals. Since
this is a "Golden Rule" type of organization, members must also be willing to occasionally help out
other techs with problems before they post their
own stubborn vehicle diagnostic problems online.
There are two types of iATN memberships: free
level and sponsor level. The free level allows you
to post your tough diagnostic questions to other
members and respond to your fellow techs with
their posts. The sponsor level allows for use of advanced features such as the new search engine that
allows you to look at resolved and unresolved cases
matching the symptoms and vehicle descriptions
you enter into the iATN case search field. There is
a video showing you the proper usage and benefit
of the new search feature in case it's been a while
since you've logged in.
