Hi Chris!

Can you send me information on how to install the complete application of the front radiator for cooling as you have it in your blue 600 you call "Amie" ?

I like your idea of keeping the front bumper in the car as well. Let me know what to do, and how you did yours so I can upgrade my 600. Mine has the 903cc motor in it, and I have the 127 water pump for it all ready. So I need the rest of the instructions to do the job correctly, and what to do?

Please let me know soon as possible so I can upgrade my "chucky".

Thanks
Luis Pinto

I have a 600 radiator with all its shrouding removed mounted in my stock battery box, and the battery mounted to the left in an old battery tray from a 124 Spider we parted out.

AMY (click for pictures) already had a fabricated metal front spoiler under the front body panel, so it was real easy to cut a rectangular hole in it for air to duct to the front side of the battery box. I used aluminum sheeting for the ducting.

For the exit of the air, the hood was already pushed up in front of the windscreen from gas stations trying to lower the front hood by just pushing down. Yes, you remember when all gas stations where called "service stations"! It was really common for all 600 Sedan hoods to be bent. If I did not want to do this, I suspect a lot of air does also go out the back side of the battery box, and it would go out under the car.

As for plumbing I run the water out the base of the rear radiator and thru a 124/131 bypass thermostat. From there it either goes to the front radiator if it's hot, or into the front radiator return pipe if it's cold. The hardest part was realizing that with two radiator caps at two different levels you had to use only one coolant overflow bottle. Both radiators have "Stantz" necks mounted on them so I can use easily available radiator caps. The rest of the system is stock.

For fans, I have a stock Fiat radiator fan sender mounted between the engine and the first radiator that turns on cooling fans mounted on both radiators via relays at 92 degrees Celsius, and off at 89 degrees. I have also built customer's cars with the fan sender mounted at the outlet of the first radiator. Amy's comes on sooner as it's measuring the hottest water in the system, not as it exits the first radiator. But both seem to work! I also put in a pilot lamp so I know when the fans are on, and a manual override, which I never use.

That should get you started. Enjoy!
