Radiator Overflow Locations?
#1
well on test n tune night at sac ca raceways they don't inspect too often or at least me. well the next time i go i got to make sure i'm legal. the biggest things last time was to make sure i have the battery secured down, no rubber hose longer than 12 inches, and a radiator overflow bottle of at least 16 ounches. well the battery is secured down like a OEM, i ran a 3/8's medal line as far as i could from the pump to the carb with minimal rubber hose (going to have to be do this with a regulator being installed soon. well so this brings me to the radiator overflow.

i didnt like how it looked on the inner engine bay fenders with the ignition module located around there or with all that other electrical wiring. or even in front of the radiator. if you mount it in front of the radiator support, the overflow tube on the radiator points towards the fender so it'll have to take a crazy loose around. so i wanted to do it inside the wheel well, i found a factory hole that i could use a self taping screw with and just made another hole to mount the bracket securely. here are some pics!!!!

I like it there Olie!
If i must use some rad overflow i´ll do the same as you... hide it in the fender inside that are plenty of room, easy access if you have to work on there and doesn´t spoil the engine bay looks...

Ollie will it suction the water back ino the radiator when it cools down. I know it is a dumb question but right now I am using my window washer tank for an overflow.

Guys... isn´t the overflow bottle supposed to be located higher than the rad hose in order to let the gravity return the cooling liquid to the circuit?

that could make sense but i think its strictly to just catch fluid if temperatures got hotter than normal and the water expanded and needed to go somewhere.

i could guarantee the bottle will almost always be dry!

the coolant will get sucked back in as the coolant cools down. I have a gatorade bottle right now. and when it cools down the liquid goes back in the rad. Not all of it but some. the over flow is good to have it prevents air from getting in to the radiator.

Eric do you need to change the cap?
