FAQ:

Q: Where to put coolant crossover on radiator?

A: Run coolant crossovers to just below that position on the radiator tank, many radiators from LS powered factory vehicles already have a nipple here. This will allow the radiator cap to relieve the steam/pressure buildup as it builds and reaches the rating on the cap.

Q: Can You Bleed the cooling system on a LSA LS9 engine?

A: This makes bleeding the cooling system on your LS1 LS2 LS3 LS6 LS7 LSA LS9 LSX engine very easy! Be sure to plug the radiator port you remove the hose from. This is best done when the engine is not hot as it can become a safety hazard to handle hot fluids.

Q: Why do I need a coolant crossover on my engine?

A: They make tuning your LS engine easier and make your tunes safer! Air pockets create pressure which increases temperature. Not having all 4 corners of your coolant crossover will allow steam pockets (aka pressure) to build up in the highest point of your cylinder head and create hot pockets.

Q: Which steam kit should I use for my LS1?

A: For instance a factory LS1 2 or 3 intake will use our V2 Flex Line Kit, High Rise Intakes like the Holley Hi Ram or Edelbrock Pro Flo will use our Stainless Steam Kit, and LSA LS9 superchargers will use our LSA Steam Kit due to how large the superchargers are and how far they hang off on the corners.
