I just put my b18c1 back into my ej6 after 1 year of having the engine out to get it rebuilt. I started it up last night, everything ran fine. It overheated and I wasn't getting any heat from the vents and there was a lot of white smoke from the front of the car. It appeared that most of it was coming from the radiator, but there were no leaks anywhere. There were no spots on the ground at all. So this morning I got rid of the air bubble in the coolant system and I can now get heat at the vents. When the car gets to opeating temperature there is still white smoke coming from the rad. I didn't notice any leaks anywhere. Here is what it looks like.

All the leaks from last night were dried up and this is what I got from running the car this morning. There are no leaks coming from the top tank, but it appears to be leaking from the core. Is that even possible? The leaks aren't streaking down from the top... they just start in the middle of the core.




There is also some coolant at the bottom of the tank where the core meets the tank.




I am still getting smoke coming out from the rad, but I am no longer experiencing any overheating.... well not as bad as yesterday. Do I need a new rad? BTW this rad was sitting in my garage for 1 year, I'm not sure if that could affect it or not.

 

Id def go out and buy a new radiator, its just a matter of days til that thing completely gives out. How much coolant are you losing on a daily basis?

 

I've only been running the car for 1 day now... I really don't know how much it's consuming.

 

if you can afford it just go to a junk yard and pull a del sol radiator.

 

I vote new radiator as well..

 

get new hoses as well. they are only a couple bucks. if u have like 10-12 dollars, get a new thermostat as well.
