Is there any type of fluid I should spray on my engine to keep it from rusting?

1 Answer

Answer :

No. generally speaking your engine block, heads and intake will be a coated cast iron or cast aluminum. Neither will rust. Also keep in mind that oil from both your vehicle and the road are coating the exterior of your engine while you drive. If you are worried about your exhaust manifold rusting you can purchase header wrap or paint them with high temp paint.
