Review on Dayco 5060875 Serpentine Belt: 🔧 Ensuring Optimal Engine Performance and Reliability by Richard Turner

Update Nov 2015: This belt started slipping within a year of installation and in September 2014 I replaced it with a Goodyear 882K6MK which works better on my SUV and is cheaper. Original Review, September 2013 All I can say is that on an older Durango or Dakota this relatively cheap maintenance - belts, spark plugs, coolant - is very helpful. I have no way of technically comparing the Factory Masters I had in my 2003 Dodge Durango SLT 4.7 with compatible Bosch (7962) FR8LCX Super Plus spark plugs, pack of 1 spark plug. The belt was half an inch smaller in diameter than the old one, the old belt may have slipped a bit. All I can tell you is that after resetting the PCM (Engine Control Module) on the car, his V8 runs much smoother and smoother than ever (I bought it used with 65k miles, it has 97k now).
