Frequently Asked Questions
Will this radiator work with my manual transmission car?
No — this radiator is built for automatic transmission cooling only. Manual transmission cars use a different core without the trans cooler circuits. Verify your transmission type before ordering.
Do I need new hoses or can I reuse the ones on my car?
Your existing hoses will bolt straight on. Inspect them for cracks or soft spots while you're doing the swap — if they're original or aged, replacing them now saves a breakdown later.
What prep work is needed before installation?
Drain your coolant system completely before pulling the old radiator. Clean any sediment or corrosion from the mounting area. When you bolt the new unit in, torque all fasteners evenly and refill with fresh coolant — don't reuse the old stuff.
