Default radiator core keeps sepatating from endtank

I replaced my radiator last week due to a leak because the core and endtank were coming apart. Now the new radiator has the same problem, the crimps from the core are coming apart from the endtank. The company is saying that my cooling system could have too much pressure. The radiator cap is stock, anyone know what could be causing this repeated failure?

Have you ever tried to use the stop leak stuff you pore into the coolant?

I wouldn't use the leak stop stuff, but you need to get this checked out.

What radiator are you using that this is happening to?

stop leak is meant to what? CLOG UP LEAKS...which also means it'll gum up the coolant passages on the engine. I'll never use it. Ever.
I'd go with bad head gaskets, and pressure from the cylinder(s) is leaking into the cooling system, pressurizing the system to much more than it was intended for.

Isn't that what this Subaru Coolant Conditioner is?

Essentially, yes. From what I've read, Subaru originally made it to seal up head gaskets that are leaking.
This persons problem seems very excessive(takes a good amount of pressure to blow an end tank off)
Fix the problem right, the first time, if the head gaskets are leaking, replace them, don't put a bandaid on it....

Since Subaru recommends you add this when you change coolant never ever is a point in the not too distant future then?

Yes, they recently just started recommending it for the turbo cars from what I've read.
I myself, will never use it. I'd rather not gunk up, clog up the engine. I've seen the inside of a 350 Chevy engine that had stop leak in it, and the coolant passages all had crap(goo) in all of them. there is no replacement for good coolant and distilled water. If you're having problems, and the head gaskets are the source, replace them. My friend recently had this same problem on his 2002 wrx. His heads were warped. He said he never even overheated the car, he saw the temp gauge above what it should be and immediately shut the car off. Mechanic tore into it, replaced the rad, blew apart again, and it was the heads.

The subaru conditioner is not "stop leak"
Stop leak has large particles to clog up leaks, the conditioner consists of only liquid.


BTW the overflow tank/radiator cap is another leak that "stop leak" stops!
