I'm interested of buying this Chrysler 300 from a guy for 1000 cash and his just telling me the timing belt is the only thing wrong and I just want to no if anybody knows an estimate price for the repairing ??? Thank uHow much to fix timing belt on a 1999 Chrysler 300m?Don't buy it until you get more info on it. The 3.5 Engine on the 300 is an %26quot;Interference Engine%26quot; meaning that if the timing belt snaps your engine is pretty much gone. The piston's and valve's collide that cause major engine damage. Changing the timing belt wont do nothing if you have bent valves. So is $1000 worth is you have to spend another $2000 to put an engine in it on a 1999 model?How much to fix timing belt on a 1999 Chrysler 300m?Around $500 dollrs or more if the belt has already gone out...
