# Heat Advisory

**By Titan Engines** · 2026-07-02

High summer temperatures put extreme stress on your Jeep's cooling system, especially classic straight-six and four-cylinders. To maintain your engine performance and avoid overheating consider these checks:

\-Inspect the mechanical fan clutch for proper resistance and engagement.

\-Ensure your radiator is free of debris and check for internal scale buildup.

\-Verify oil integrity; extreme heats breaks down lower-tier lubricants faster, reducing critical parts protection.

Don't risk your engine's longevity!
