Did you all keep your original radiator? If so, did you change the relief reservoir to a closed expansion tank? Or if you kept the relief reservoir, what psi radiator cap are you using?

Thanks.

I figured out the hard way that my radiator had a leak (it finally sprung a stream). I still get a coolant 'smell' because the stock reservoir is just open to the air at the vent tube, I think. Of course it is a lot better since I put in a new radiator! <grin> I need to ground my relays to make sure that my fan is coming on. I wired a two speed fan to be controlled by the ECM with two relays... one for low speed and one for high speed and SpeerTech was supposed to set them up for 195 and 210. So far I'm running at about 195 on long drives but it gets up around 210 in town in traffic and it's not hot out yet.

I do not recall exactly, but do remember there is quite a bit of clearance, car is at my shop and I am home at the moment. Never had any problems with anything hitting or rubbing.

Yes, I made the lines up using the manifold assembly from the donor vette. The orifice still lives in the original elky evaporator core, no need to add anything.
