when i get cx racing heat exchanger can i take out my stock heat exchanger
and right now i got the stock h/e in my car and my dex cool is low in the spout i open the cap and fill it up and turn on my car and it bubbles and goes down ive put in about a 1/4 of a gallon of coolant in it and it doesnt seem to fil up but i got no leaks in the system at all can any help or have this problem

 

just leave ur stock one in and add the new one.

 

run both for better cooling i run the stock and the ca heat exchanger

 

any real disadvantage to get rid of it cuz if i take it out there more air and a chance for my radiator to breath i was asking if i have to leave it in if it serves any purpose inthere

 

You're question has already been answered. Leave the stock one where it is at.
