1994 - 940t coolant line leak ?

Discussion in 'Volvo 940' started by ~^ beancounter ~^, Mar 22, 2006.

  1. has anyone had a leak in the (1/4" hard "pipe") coolant line, that
    attaches to the top of the radiator...on the left (passanger side - us)

    .... i think this line is going to or returning from the tranny
    system...anyway, it is leaking where it goes into the radiator...any
    fixes or sugguestions on this? other that buying a new
    radiator..??...thanx...

  4. JB Weld is a steel filled epoxy available most places adhesives are sold -
    hardware, auto stores, places like that. It comes in several versions, from
    the original that takes a couple hours to set to "JB Kwik" which sets in a
    few minutes. Heat speeds the hardening process. All take a day to harden
    completely, but are workable with files, saws and sandpaper when hard. On
    metal surfaces it is reasonably permanent.

    Be sure to remove all traces of oil with alcohol or brake cleaner before
    applying the epoxy.

  5. thanx folks for the tip...i picked up some
    radiator weld, and applied it...i let the car
    sit and "set" for 12 hrs and just drove it
    and got it warmed up...it seems to be holding,
    so far...does anyone know aprox how many
    lbs of pressure the 940t coolant system "pumps"
    up to?....thanx, (as always) for the group help....

  7. Like most, somewhere around 15 psi. Certainly below 20 psi.

  9. The leak is fixed but are you sure you have solved the issue as to why the
    radiator leaked.Is it worn out clogged ?But if it was obvious damage,such as
    a stone ,you might be safe.
