A Permanent Fix To Repeat Radiator Failures?

I'm wondering if there will be a similar fix for 6.7L trucks?

Looks like they put a lot of work in to that engine...  Am I the only one that noticed the WIX filter?

But why do easily driven highway queens leak at the bottom corner and have unharmed mud dauber nests built in the cells of the rubber rad mounts?

I would think others see rough and tumble truck leakers where flex could be it and the ones that are pristine in the wheel housings and frames with seams leaking and have no discoverable issues with t-stats also leaking.

Agreed, why would gas radiator not leak if twisting was the problem.

I think it's something to do with the amount of torque that the motor puts out. Even if you put one of those crossmembers in it's just gonna tear up the next thing in line. Kinda like the frame cross members on semi trucks. The high horsepower trucks tear them out faster.

Chevy gas half tons have a problem with tank to core seperation. They have actually recalled some. They blame it on excessive thermal cycling due to a faulty thermostat. I would be curious to put temp probes into the end tanks of a 6.4 truck and see what is up. I have changed way more rads on pavement pounders than bush units by far. I don't buy the flex theory.

I've always thought it was thermal shock. Shit be boiling somewhere. Something has to give.
