I just but a b18c1 in my car and I have noticed that ever since I had it put in, My radiator coolant level drops rapidly. I just filled it up last week and its already almost gone!!! So I check for leaks, no leaks, checked if my radiator was cracked and it was fine. Could my stock ex radiator be too small?? Is it not getting the job done? Please help any suggestions appreciated!!

 

check your oil level and thickness.

 

Its either.....
1. Going in your crank case
2. You did not bleed the cooling system right.

If its number one, you have a problem.
If its number 2 your ok. It will just keep doing it until all the air is out of the system.

 

How would I check if its going in the crank case??
