12.7 Detroits blowing radiator hoses due to coolant additives????

With long life red you don't need a filter, just block it off, most hose problems I have seen are from switching from green to red, but nothing should hurt a good silicon hose. Wonder if you got a bad batch of hoses.

 

You should not be constantly replacing filters with new filters that contain the most additive possible every time. You should be testing your coolant, finding out how much SCA's it needs (if any) and then either adding a filter with the correct amount and release time or just adding the correct amount of liquid additive. If it tests fine just throw a standard filter on with no additive, if it tests to bad, flush it really good and refill it with extended life red like the others said with a decent additive if needed to level out SCA's and put a filter with no additive on.

 

The blue silicone hoses should last like 10 years. If you dump the green coolant and switch to the red ELC Extended Life Coolant that stuff is good for like 500,000 miles or 6 years. Just put in blank coolant filters, coolant filters without any additive.

 

Make sure your mechanic is not using any grease at the hose ends when he installs the hose or using motor oil,,this includes on filters too,,this will kill a water hose in a very short time

 

What worries me is if it WAS coolant additives, i wonder what the liner o-rings look like now.

I have seen people just add coolant additives without understanding how they work and what they do. Its very hard on any oring or rubber hose if you get the SCA additives too strong. Makes them brittle and hard.

Fleetguard says they approve different brands being mixed into a cooling system, but i never liked doing that. Buy 1 brand and stick with it until flush time or major cooling syatem repair. Less chance of a bad chemical reaction in the system in my opinion.
