Motor Vehicle Aircon Regas Questions and Answers FAQ’s

Air Conditioning No Comments

Car Refrigerant Regassing

DenLorsTools.com Summary: Motor vehicle air conditioning questions answered from all over the world by a master air conditioning technician in Florida. Simple to understand terms are used to resolve issues and to help the reader understand problems with their car’s Air con system (A/C system). Low gas (refrigerant) is the most common problem a car’s aircon system could have, but it’s not always the issue. One shouldn’dt assume that the solution is always to top-up (top off) a system. A re-gas that adds too much R134A only causes more problems. Many garages will do a free pressure check. However, simply checking the pressure readings is not a foolproof test of the air conditioning system’s health. But, a knowledgeable motor vehicle technician can make a good evaluation of the A/C’s performance based on the readings and a visual inspection of the components. After evaluation, a regas (recharge) may be done or a more accurate fill of refrigerant can be performed by removing the remaining refrigerant, vacuuming the system down and recharging with the vehicle’s specified amount of gas.

Why Special Tools are Required for Time Sert Inserts

TIME-SERT Kits No Comments

DennisBDenLorsTools.com Summary: Special tooling is required to properly install Time Sert inserts. I know sounds like it’s either a no brainer… or a sales pitch to make customers buy expensive thread repair kits. Well apparently it’s hard for some to understand that proper tools for the installation of Time Sert inserts are necessary. That’s the reason for this quick auto tool blog.

Maybe it’s the economy. But lately we have been inundated with customers that are really trying to save money. Hey there’s nothing wrong with being frugal or as I like to say “being conservative”. However this is a line that can be crossed. The problem with trying to skimp on tools and just trying to get the job done as cheaply as possible is that “sometimes the job is not a success“. A failed repair ends up costing more in the long run. It’s takes more time, it may damage components beyond repair, there’s more down time, the repair may not last or it may not work at all.

Some customers want to purchase just the insert. Read on to hear how some of the conversations go.
