Fluidyne Radiator leak

Hey guys Im having a frequent problem with my car... I just recently bought and installed a fluidyne radiator all aluminum and it lasted as long a month and now its leaking this is the second time it's leaked from the same area! I had an all aluminum mishimoto and when it failed on me I thought it was defective so when I saw that this one leaked from the same area I was getting seriously concerned about my car I don't know if I have another defective radiator or my cars engine is causing an extreme amount of pressure to cause the radiator to leak... I experimented by releasing the pressure from the resivour (which is dangerous when hot) as I uncapped it you can here a good amount of air escaping after a normal school to home commute and after leaving it uncapped overnight the radiator didnt leak! Whats the problem? It isnt the hoses checked them and replaced them.

Make sure the cap is good. Maybe just replace it. It may be building up too much pressure before it relieves. Also where is it leaking from? If it's hose connections, you may want to replace the hose and use better clamps. Do not reuse spring type clamps.

Wait... The cap itself will relieve pressure? I don't know much and I'm still learning so help me out and yes the hoses and clamps are new (:

The leak is coming from one top corner and the bottom corners of the radiator core

I have hears several instances like this with fluidyne radiators. Mishimoto has a no questions asked warranty though. Even if you get in an accident they will replace it. It would take extreme pressures to do what you are doing and i highly doubt that is the cause. Its probably just a coincidence

The caps are rated at about 14-16 psi I believe. Overflow tank will hold the excess. Any more pressure than that can do damage. I have a mischimoto and love it. The quality and price are way better than the fluidyne. Make sure the radiator is not in a bind when you install it. The hold downs should line up easily don't force them.

Ok, I'll just give it another try with the new fluidyne that's coming in since this one is still under warranty from LRS, it's on it's way here and I just need to send this one back so they can ship it to Fluidyne and they'll find out what happened or what was the problem
Should I still replace the cap?

Yeah. Replace it. It's cheap and worth a try.

Ok, and should I get a mechanic to install it instead of me and a buddy doing it?
Maybe he can figure out what the problem was.... Maybe the whole system needs to be flushed out?

Not really man. As long as it's not in a bind and not rubbing on anything it should be ok. I had to alter one of my top brackets for some reason because the misch didn't line up right. That should be it though. It doesn't take much to put a hole in one of the passages.
