Diesel Engines Run Hotter Than Gas Engines — Your Cooling System Cannot Fail

Diesel engines generate significantly more heat than gasoline engines. Florida’s climate puts additional demands on your cooling system year-round. A coolant leak, failing water pump, or clogged radiator on a diesel truck can result in overheating that warps cylinder heads and ruins engines in minutes. FloState diagnoses cooling system problems early and fixes them completely.
