Oil Temp & Thermostat FAQ

Why did TR choose a 180°F thermostat?

The 180°F plate balances daily driving and performance. It keeps the cooler bypassed until ~180°F for normal warm-up, then opens (fully ~190–195°F) to control oil temps during load so the FA24 stays in the ideal ~200–230°F range.

Do I need a 200°F thermostat?

Usually no. A 200°F plate simply delays flow to the cooler, which can raise steady-state temps by ~10–15°F. It doesn’t increase peak cooling capacity.

Will 180°F run too cool in winter?

No. The thermostat keeps the cooler bypassed until warm. In very cold climates with short trips, minor airflow tweaks (e.g., slight grille blocking) are more effective than changing thermostat temp.

What oil temps should I expect?

Cruise / mixed driving: ~185–215°F
Spirited or hot weather: ~210–240°F (airflow & mounting matter)
Extended idling: temps may rise due to limited airflow across any air-to-oil cooler

Track use tips

Ensure clean, direct airflow to the core, avoid hose kinks, and recheck fittings after initial hard pulls. Monitor temps as usual.
