Oil cooler lines again….

[DHBWA]

Mine are weeping but not enough to worry about “yet”.

 

Not really looking forward to replacing like for like. Just replacing the hose by cutting off the crimped ends seems doable but the lack of barbs spooks me.

what about these https://www.fitzall.com/CR-1017.php

 

or am I just adding another potential catastrophe failure point….?

What engine? How many miles? What year is your truck?

Could get some sand paper. Rough up the metal lines a little. Then get a flaring tool to make a lip before sliding hose over. Use 2 clamps on metal tube. The screws to tighten 180 across from each other. 

 

Or.

 

A hydraulic shop should be able to make custom hoses to replace OEM.

I didn’t want to replace with another set of factory lines given how quickly the originals started leaking, and I didn’t like the idea of clamping with no barbs either.

 

I ended up cutting the factory lines just before where the flex line crimps were on either end and bought a flare tool and flared them (I took them off the truck for this) and used AN fittings and flexible braided oil line to make new flex sections.

 

That was just over 2 years/30k miles ago and it’s still going strong.

I bought 1/2” hose and the wide SS T-Bolt clamps. Easy job cutting the crimp and removing old hose but no matter what I have an ever so slight weep. The hose slid on too easy but it’s definitely 1/2”.

i hate thinking about going to 3/8” hose. 7/16 would be perfect but can’t find any….

Going to try standard clamps doubled up and or flaring the line a smidge more. Easy fix if I can seal it 100%. It’s actually just the two in front and lower. Weird the two harder to reach connections seem dry…..

any ideas??

[DHBWA]

Moved the wide clamp down over slight flare which left enough room nearer the end for a standard clamp. So now it looks goofy but isn’t leaking. Probably could just double up on std clamps. 
With just the wide clamp socked down I could still rotate the hose but can’t now…

I have a 2019 Chevy Silverado Trail Boss 5.3 mine started seeping at 60,000 miles cut the end of the crimps off and use 7/16 AN-8 Braided line with fuel injection hose clamps.is the right size it's going to be tight that's what you want but it will fit. These guys saying 1/2 hose it's too big it will leak. 7/16 is hard to find at all the auto parts store I ordered mine online.
