Kelvar coolant hoses

I fitted a new kelvar reinforced bottom radiator hose 3,500 miles ago to my minor supplied by a well known trader. Last night I drove the car about 4 miles and parked it in a tarmac car park when it was still daylight. When I was walking away from the car, for some reason I turned round and spotted a drip on the ground. Went to look at it a bit closer to find a puddle by this stage and engine bay sprayed with coolant. Lucky I noticed it then because I returned to the car in darkness and I wouldn't have noticed then. I thought it would have lasted longer than it has. So much for being reinforced and recommended.

Kevlar may be great for bullet proof vests, but cotton string or whatever is used in normal hoses actually works a lot better.
I think the rubber soaks into it a bit and really binds the whole thing together.

Regretfully the supply of kevlar hoses leaves a LOT to be desired. The older hoses lasted 10+ years without problems, the new ones are, in my experience, pretty useless. I've invested in a set of silicone hoses and will report back on how well they last after a couple of years.

The last Kevlar hose I fitted (or should that be tried to fit) broke before I'd even got it on. The heater spur came away while I was attempting to get the hose onto the water pump. I use rubber hoses now.

Far better using Samco hoses last forever
