Examples where the AN10 Heater Upgrade Fittings can be used?
As our fittings are really quite a popular option we have a few examples where these kits have been used in the past.
On one customers vehicle the car was built as a track dedicated drift car. The heater system itself was added weight so was fully stripped out from the car.
This car in particular only required our block fitting so the flanges were not necessary.
They were able to achieve a complete heater delete from the front port to the rear port allowing the coolant to still circulate which is the correct way to remove the system.
On another customers vehicle was a certified street car. The heater had been bypassed due to the brittle broken away heater core outlets we talked about above.
With our kit they were able to regain the function of the heater. The customer also wanted to tidy up the system beneath the intake and remove all unnecessary hoses.
This was achieved and he also regained full function of the heater.
