Milodon High-Flow Thermostats

Milodon high-flow thermostats greatly aid the correct functioning of a high-performance cooling system. They're engineered to warm the engine to a proper operating temperature without making it run hot enough to lose power. Also, the "Balanced Sleeve" design equalizes the pressures exerted on the thermostat. This counters the undesired effect of increased flow from a high-volume water pump, which actually tends to hold a stat closed.
