Flushes on vehicles


#1

Is it necessary to flush out various parts of our cars with less than 30k ie Engine flush trans flush coolant flush brake flush power steering flush are any of these really necessary and if so when ???


#2

No, these flushes are quite unnecessary.

We are seeing a disturbing trend of many service centers to automatically recommend such flushes to every customer who crosses their threshhold. The tehnicians don’t even check the level or the freshness of the fluids. You could have flushed everything last week and they will still tell you you’re due.

Still, your car will benefit by certain fluid exchanges at regular intervals. See your owner’s manual for a schedule. Keep records, and disregard the solicitations of the profit-seeking mechanics.

Well honestly here’s how you find out whats best for your car. I tried this.

Take your car to a dealership, listen to what they suggest. Next take it to a nondealer and tell them what the dealers said, you’ll definitely hear two arguement. Now make sense of the two, if necessary get a third opinion.

Good Luck.

coolant flush only at required interval in manual. transmission is a drain and fill only, no flush and the rest really is not necessary, Good oil with reasonable changes will not require any engine flush


#5

With rare exceptions, it’s necessary to do what’s listed in the owner’s manual and nothing more.


#6

The only flush needed is a brake fluid flush, when the brake pads are replaced, its usually part of the brake job. Everything else is drain and fill in accordance with the schedule in the owners manual.

One exception would be Toyotas with the 4 speed auto. The trans fluid should be changed about every 30k. No flush though.

Not all of the things you mentioned are required or necessary. Brake flush? Dont even listen to people who say that is necessary. Brake fluid should be flushed only when air or moisture has entered the system for whatever reason. Power steering, Some people say that you should do it every so often so that it doesnt smell burnt but 30,000 miles is too soon. Read your owners manual. That will explain everything that needs to be done and how many miles you should do it at. An owners manual should be read before you even drive the car for the first time. It is a person’s best friend because it keeps you reminded on when you should have your maintenance done.

Dont even listen to people who say that is necessary. Brake fluid should be flushed only when air or moisture has entered the system for whatever reason.

Which happens during normal service.


#9

Methinks, that when some people say that an automatic transmission flush CAUSED a problem, that they had a problem BEFORE the flush, which they were trying to cure WITH the flush. ----- IF a flush is done with fresh automatic fluid as the flushing agent, and the transmission’s own pump is used to push out the old fluid, it seems like a satisfactory technique to me. ASK the shop IF they use Any chemical in the flush. If they say, “Yes”, YOU decide.
