Question about 2008 Toyota Yaris Sedan
A friend suggested that my car might need a engine or transmission flush, what does it mean?
Can a engine or transmission flush damage my car?
Engine & Transmission Flush
You might have been told, by your dealer or mechanic that your engine oil or transmission fluid are very dirty, & an engine or transmission flush, is recommended. The flush will clean the engine or transmission, & those will last longer. This is only part true a clean engine or transmission will last longer, but I'm not sure that flushing them is the best way to clean them.
What Is An Engine Or Transmission Flush?
Flushing is forcing high pressure of fluid against the normal flow of the fluid. In simple words if the normal flow is left to right, the flush would force the fluid right to left.
This is done by connecting a machine that will force special solvents back through the engine and transmission. The idea is that by forcing cleaning solvents backwards through the system, it will get all the junk and garbage that has formed over time and "flush" it out of the system. In theory this sounds very good, but in practice, it can be dangerous.
The Dangers of Flushing your Engine or Transmission
Flush machines force high pressure cleaning solvents back through the engine and transmission and clean out some of the accumulated junk that has formed, so far all is good. Now the problems start, engines have small passages and galleries through which oil or automatic transmission fluid flow and there are one-way valves that keep the fluids from backtracking for whatever reason.
By using an aggressive cleaning procedure like flushing, large chunks of accumulated sludge are broken off and forced backwards through these galleries and valves and, more often than not, lodge tightly and block them. This cuts off the normal flow of the fluid and causes lack of lubrication in an engine and abnormal or no shifting in a transmission. The results are expensive repairs, or more often, engine or transmission replacement.
That's my knowledge about the subject, hope it was helpful,

The 2003 escape doesnt have a servicable transmission filter. The transmission flush should be done every 30k miles on that transmission or you could develop the transmission shudder that is so common. Once it starts youll never be able to get it to go away compleatly . My 6 year old and I did the flush in about 30 min with only a hand full of wrenches and alot of fluid. google escape transmission shudder and youll find links on the flush. Do it right away if you havent already seen problems.
