Hello could you give more details
hoses are soft while running... fluid leaking at the rear end of motor.dripping underside rear of engine
Sound like you have a hose leaking andtifrezze, the best thing to do is wait until the truck is cold and top off the antifrezze and you need radiator pressure test to pressure the system and found a leak.
without a pressure tester will be very hard to find this leak
ok thank you
