    Thread: Lots of steam from cooling system

    1. 08-13-2019 01:23 PM #1
      I was driving on the highway for about 40 miles when the low coolant sign appeared (I know that the coolant level was good before driving)
      I stopped on the side of the road to notice a LOT of smoke coming from the engine bay : a hose going towards the heater had punctured. Got the car towed and replaced the hose : not leaking anymore.
      Drove it again today for about 20 miles and noticed a smell of coolant. Got home and another hose was leaking !
      It is the small hose connected to the upper rad pipe. The car is a 12V VR6 jetta and it stayed spot on the right temperature all along, is there a reason that could make the pressure go too high or something like that ? Thanks !

      Yes they are... I was thinking about a stuck thermostat, but that would make the car overheat, right ? Maybe the hoses were just overdue...

      T-stat could be an issue. It sounds like there is restricted flow somewhere in the system so it can only be one of several things. Check: Low coolant, incorrect concentration, radiator(buildup inside or debris in front of it), coolant pump, thermoswitch, or bad fan control module.

      Must be just coincidence. Do you know how the old hoses were?

      This wouldn't surprise me at all. Especially after that hose may/was run with low/no coolant for a minute. Old hoses wont like that.

      I'd replace it and move on.
