ever since I swapped a b16a3 in my eg, i notice that I am short on rad fluid when I check my overflow resevoir, I top it up go out and when I come back home, resevoir empty, after some checking, I noticed that i'm leaking rad fluid from tthe opposite side of the rad, from underneath it is collecting by the oil pan, i'm assuming it's the water pump, what do you guys think? also I got stuck with my d16 rad, my car hasn't overheated yet and it's been damn hot all summer, does anybody have an opinion on whether or not I should switch to a bigger rad? Or does anybody know what type of rad a b16a3 came equipped w/ from factory?

 

I am not real clear on your description of where it is leaking from. Could be hose problem.

The b16a3 (del sol) came with a dual core radiator.

 

If its leaking near the timing belt side of the oil pan...then its your water pump..Also...Thats rad. should be ok..You should upgrade to a 99-00 b16 radiator
