Ive started to going through my Westie as it is starting to heat up so I was in the back and pulled out the rear seat and under seat box and noticed that the floor was a bit damp and I couldnt find any thing obvious so I started her up and let the motor warm up and had a closer look at the rear heater and wiggled the top hose and got a squirt of coolant from between the coolant shut off and the inlet of the core.
So i eventually pulled it apart and the O ring was flat and on the way out so I replaced it and the problem went away!!
Not happy about the plastic fittings back there!  _________________ A sad looking 88 Westfalia, MT 2.1 with 150k on the clock and several issues! |

Same here when I pulled the bench seat out to soundproof the floor. O-ring was flat as a pancake. _________________ __________________________________

These vans are long on the tooth. 25 years is a reasonable lifespan for a rubber o-ring to me. At least the part is readily available and cheap. _________________ SyncroFest Schadenfreude!

Be prepared to spend about a whopping $0.63!!!
A handy hint in case you didnt think of it, use 2 pairs of vise grip pliers to gently crimp the hoses so the coolant stays where it should!

Mine was too, and starting to go hard and did break in the end.

|

So my tintop had this happen too, and I posted a thread about the subsequent issue of cleaning up the sweet slickness of coolant spilled into the floor, and soaked up by the underlayment panels/boards. They're like compressed or chipboard with rubber backing. And now mine are saturated w/ coolant, and I've laid them in the sun for several days, still when squeeze the edge a little, it just squishes out the slick stuff.
Anybody know a good way to clean and dry these boards/panels out? They're No longer available from any vendor I've found . _________________ Dave

With the floor still in the van I loosened the boards and wedged silica gel packs under them. Then I ran a space heater in there for a couple of days. Seemed to do the trick. _________________

I tried washing mine but had to throw it out due to squirrel nestings in the parked van back in WA. I put in a floating laminate floor and took out the rear heater (sstored it for next owner if wants) _________________ 83.5 Vanagon L Riviera Model with 97 1.9L TD AAZ 4 speed Daily Driver 3 out of 4 seasons (for sale)
