i got a 98 b18b1 in my eg . it runs great and all but it loses coolant. the problem is i dont know where its going... ill fill it up and drive it for a week and then all of a sudden its empty. there are no drips or leaks that i can see. anyone heard of this before...any ideas?? any help appreciated

 

Are you filling your radiator up, or your overflow? If you are filling your overflow and not your radiator it could just be that the radiator is almost bone dry and all the coolant you put into your overflow is getting sucked into the radiator.

 

filling up both everytime

 

Did you recently do the swap in your car, or have you been driving it around for a while and it just started doing this?

 

had it for a while...just started doing this

 

And you cant find a leak or see any drops? Let your car run for a while in your drive way and watch it.. There is no way you are losing 5+ quarts of coolant without it leaking out somewhere.

How long does it take for your coolant to run dry after you fill it back up, and about how much do you usually have to put back into it?

 

it takes like a week for it to run out.....about half a gallon

 

maybe its burning water...but more likely its leaking coolant, if you cant find it letting a professional deal with it would be a good idea.

 

check the seal on your radiator cap. you might be evaporating coolant out that way.
