CSF Frequently Asked Questions

Will a CSF radiator or intercooler fit my truck without modifications?

Most CSF applications are direct-fit replacements designed to use factory brackets and connections. Verify year/engine before ordering.

How much cooling improvement can I expect?

Results vary by setup, but customers typically see notable drops in coolant temps and intake air temps, especially when towing or running higher boost.

Is aluminum really better than the stock plastic-tank radiator?

Yes. All-aluminum, TIG-welded construction resists seam failures and heat cycling better than plastic-tank designs.

Do I need tuning after installing a CSF intercooler?

No tuning is required. However, lower IATs can help your current tune run more consistently under load.

Can I install CSF cooling parts at home?

Many DIYers install CSF radiators and intercoolers with common tools. For best results, pressure-test the system and use fresh coolant/hoses where needed.

Does CSF offer a warranty?

CSF products include a limited manufacturer warranty. Keep your proof of purchase and follow install guidelines for coverage.
