so, i have the stainless steel braid hoses for my oil cooler from mazda trix. Well one of them got a hole in it. Was rubbing on part of the frame i guess. Well i dont really wanna spend the cash so i was wondering if anyone has any ideas for a fix. Just a small hole, smaller than one of those really small nails used to hand pictures on drywall. i was thinking of some sort of clamp. 2 halves ( and ) and then just bolt them around the hose. Anyone think it will work or have any other ideas?

 

This should give you some ideas. If you want the ss braided look, go for one of those slip on covers. I would not try patching the hose, too risky, and it will be very hard to get a secure seal due to the braiding.

^^^^^^^^^^^do not attempt to fix. dont skimp out, thats how you lose an engine. just replace the hose with a new one and be very careful not to overtighten the fitting on the oil cooler.

 

Yea dont cheap out,that hose is your engines lifeline.It fails,your engine is toast.

If you take it to a bearing/hydraulic shop,they could probably cut the hose at the hole,install a double nipple,and re-crimp so its a permanent fix.
Might be cheaper than a complete replacement hose and it'd be perfectly safe and adequate since our oiling system is hardly at a pressure/temperature where braided stainless steel lines are neccesary.True hydraulic lines are made to handle 3000psi, and hundreds of degrees of temp.Our engine rarely exceed 100psi and 200 degrees.Ive been using B-stock rubber/nylon hose and double screw clamps for years and years with no problems.And they dont eat through everything they touch like SS lines.....

 

when my oil-cooler line got chewed up by the power steering pulley i sent both lines to this one shop in austin and he made new lines using hydraulic hoses(over 4k psi rating) and just put the fittings back on....now i dont get no more leaks...the line going to the front of the motor needed a 90degree fitting cause its just too hard to make it bend that much
