2008 Jeep Compass ,2.0 LT engine 2WD, Northern Edition. 150,000 km's showing and hopefully put on many more before having to consider replacing vehicle... I'm of the " If It's Not Broke , Don't Fix It " theory.. But keeping with Preventive Maintenance I'm curious about Engine Flushing.. The Heater is top notch in the Winter Months, almost instant heat from a Cold Start... On the subject of Flushing my 2nd thought was Flushing the Transmission... It's a Constant Velocity Transmission ( CVT ) It has never given us any trouble and I have never gotten myself in a situation to be stuck and rock the transmission back and forth from Forward to Reverse. Nor will I ever think of doing such a thing as I know of the abuse at that moment... Thanks

Go with what's specified in the Owner's Manual.

Engine flushing is so a no-no that Chrysler, GM, and others have issued service bulletins warning their dealers not to engines. Read this post on engine flushing

Should you do an engine flush

Be careful when flushing the engine it can cause leaks in the engine. After a while rust builds up in the engine and clogs small leaks that you do not see . I have seen flushing causing more problems then it helps.
