523 Ice Cube Question

[dgwray22]

Hey all, i got a 523 Ice Cube Kit put in about a year ago and now im loosing coolant out the expantion tank. it only comes out under a good load. I have no white smoke out the exhaust, ive taken the radiator cap off and there are no bubbles even if i give it some throttle, and no coolant in the oil. runs great besides having to add coolant. I also put an aftermarket water pump on not sure if that has anything to do with it, stock radiator and cap. Im just hoping its not the head gasket. want to check out all my options before i rip it open. was going to put the system under pressure and test it but dont have the right size cap. anyone have any ideas?

Thanks

Also check out my Carb Question. Are they worth the money? Do they really make a night and day difference. I have the head ported and polished cams ect. stock carb. 2 1/2 inch intake with k&n.

Thanks again.

Sounds like the head gasket is leaking compression into the coolant system. Check the torque on the head bolts first. The bigger carb will let more air into the engine, with all the other mods, it should make a noticeable difference.
