HAS ANYONE HAD THIS HAPPEN TO THEM, AND WHAT CAUSES THIS?

I FOUND COOLANT ON TOP OF MOTOR NEXT TO CARD. I CAN NOT FIND WHERE IT'S
COMING FROM. I HAVE A STOCK 12A ONLY MOD HEADER. THE CAR DOES NOT OVER HEAT AND COOLNT LEVEL IS OK, THE AD COOLANT IS ALWAYS ON THOUGH.
ANY IDEAS WHAT COULD BE GOING ON. (hard time with search)

THANKS

Replace the carb gasket and install freeze plugs. coolant flows through the intake.

Yep, its gonna be the intake manifold o rings leaking, not too bad of a job, couple hours and a lot of cleaning.

I have to suggest not going with the freeze plugs unless your building a "race" car. Theres a reason mazda runs coolant through the intake. Helps with fuel atomization, and cold starts. Your car will take alot longer to warm up and run correctly and get worse gas mileage. Just mu opinion though. I recently had to do this as well.

i have noticed no change in mileage or start ups. However, my car is garaged.

Thanks Guys Your A Big Help. Now For The Big Question Where Can I Find Info On How To Replace The O Rings Or Where R They Located On The Carb
Thanks Again

You would have to take off the intake and put a new gasket and new o rings on. The o rings go between the motor and intake.

I have freezeplugs on both my 12a's, and it doesn't affect it very much, it might take a little longer to warmup in the winter (and NJ winters get cold) but not much longer, then again the RB header radiates plenty of heat in that general area

i think you should use freeze plugs. i didnt and i wouldnt go back. now i can take the manifold off and not have to worry about spilling coolant everywhere. i DD mine and i didnt notice any loss in MPG or driveability with them.

The add coolant light comes on from the sensor thats on top of the radiator. If the level is good then the sensor is probably bad.
