Flush Systems: A Big Taboo
In Honda/Acura vehicles, the transmission, as well as the systems that
handle lubrication, cooling, fuel, and power steering, are designed to give
thousands of miles of trouble-free service if you follow the maintenance
schedule to the letter.

Flush systems are a popular aftermarket offering these days. These products
look impressive and make lots of claims, but American Honda strongly
recommends you avoid using them on any Honda/Acura vehicle. Here’s why:

* The maintenance schedule neither requires nor approves of aftermarket
flush systems.
* Flush systems take time to do; this adds to your service client’s wait
time.
* Flush systems haven’t demonstrated an improvement in vehicle performance
or reliability.
* Flush systems using solvents may leave solvent in the system you’re
flushing. This will dilute the fluid or lubricant and degrade its
performance.
* Flush systems using filters can filter out vital additives and degrade
the fluid’s or lubricant’s performance. This is particularly true for
coolant.
* Any damage caused by flush systems isn’t covered by warranty.
