steve this system is to separate the water system (factory system goes through the radiator),( to lower IAT"s.. the tank, the heat exchanger and the motor with those valves closed the water in the heater never goes through the radiator ,,,it goes from the inter cooler pump to under the supercharger to the intercooler then to the heat exchanger then back to the intercooler pump remember on my car i had the killer chiller and my iat were 45 to 60 degrees most of the time yet my engine temp was 190. ,,you could have used a limited tank (as it only has one hose connection ) and saved about $100.00 jim
call me if you have any questions working on my newest V8 crossfire
