-Is the engine running?
-Is this while the vehicle is in drive?
-ETC?
yes it stills make noise and i don't know whats going on with it, i was told it might be a rod or something else. i was told that it need wires, oxygen sensor and cat converter.
why is my '99 ford taurus making a knock noise and smoking from under the radator
replace the belt with a goodyear bet
no noise- no problem
it might be your starter.
The Ford Taurus does not have a timing belt, it has a timing chain. The timing chain is designed to last the life of the engine, and does not need routine replacement.
The 1996-1998, and much of the 1999 model Taurus & Sables are virtual twins of each other - making the parts highly interchangeable.
It 's your dang old cam shaft syncronizer.
No 2011 Mercury Sable model , but there is a 2011 Ford Taurus
Have the charging system tested, I'm thinking maybe alternator is over charging and causing the belt to slip on acceleration.
wheel bearing
Yes, a 1999 Ford Taurus Sho Engine will fit in a 2007 Ford Taurus.
Low transmission fluid or a bearing is going out.
