SERVICE INFORMATION
In 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 vehicle. Heres why:
- The maintenance schedule neither requires nor approves of aftermarket flush systems.
- Flush systems take time to do; this adds to your service customers 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.
