I just swap a d16a into my 94 HB and have been having some problems. First the ECU was bad and I got a new one and got it running. So I take it for my first test drive and everything seems to be ok. I pull into a gas station and notice some smoke coming from the hood. coolant had come out from the radiator cap. So I went and bought a new one and it seemed to fix it. Later that night I was driving and got on it again and I noticed a whole lot of smoke and I started to overheat. This time it shreaded the hose that enters the engine just under the dizzy. So I fixed that, filled it back up and started it and it came shooting out the cap! It was like a fountain out the top of the radiator it shot like five feet out of the radiator! So then I remember a kid telling me that you have to bleed it or something so you don't have any air bubbles? So we tried that and it seemed to work. Took it on another drive and it was perfectly fine. Then I got on it to test it and this time it blew the upper radiator hose in half from clamp to clamp. The whole way. Sorry about the long write up I am just very confused as well as some of the people i have talked to. What could be causing this? Do I just need to get better coolant lines or do I have block somewhere?
