Is the Chrysler 3.5 engine any good?

Great car and so far great trouble free engine and everything works like new. I do add injector cleaner about every six months. As best I can tell if you maintain the the 3.5 you've got a 250,000 to 300,000 mile engine.

How much did it cost to get the timing belt replaced?

Thanks, Steve

You are correct my mopar man....................

replying to Steve Stone, Richard wrote: Quite agree Steve, spot on advice re oil, and the weak bottom end....a basic engineering design fault, to not provide a shade more bearing width, and the extra drag too minimal to shave even 1 mpg off the standard. It is staggering to see a team of Chrysler design engineers so incompetent as to provide an engine that is on a par with a 1960,s engine....narrow bearings and too high a load to cope...but they lasted longer then even with the rubbish oils of that era. I have a very dim view of today,s engineers, where even Lexus get it wrong...too many smart letter after a name , and no spanner experience makes a crap designer. .

355000 miles on my 99 'trepid only replaced the spark plugs, coils, timing belt with pulley and water pump. Oil and filter change every 3000 miles only with conventional 10w30 walmart tech oil.
