The fan is multi stage.I have a 2001 Z06 and am having some overheating issues when stuck in traffic. Does anyone know if my engine has a single stage or multistage fan and at what temperature would it kick in?
Definetely. After driving all year and assuming this just started, trash in the radiator cavity is the most likely culprit.:agree:The fan is multi stage.
Your two most likely culprits are
1. low coolant level
2. crap in the radiator
You will want to check for bags, grass, leaves, sticks,etc. in the radiator before troubleshooting elsewhere.
