Hi folks.
Bentley shows only a 1.5 litre difference in cooling system capacity between the WBX and Diesel Vanagons.
Is it really only that small a difference? i.e. does the WBX engine only "hold" a little more than the diesel? Or is the difference at the rear heater one typically sees on a gas Vanagon?
On my '81 with ABA 2.0 inline 4 cylinder, I cut the long coolant pipes and disconnected a heater hose at their lowest points, and replaced the thermostat. I assumed all or nearly all the coolant would drain out in spite of having the right rear wheel up even a little higher than front of van. Maybe coolant remained in the radiator? _________________ 1981 Westy DIY 15º ABA

I will let you know how much coolant I put in sometime next week. It really should be the same as a diesel cooling system. The Wbx has a rear heater and 1 1/2 cooling lines. That should be right. |

I honestly can't tell you an answer to the question, but I'm sure the differences are insignificant. I can say that bleeding the air out of my coolant system is the easiest of any water cooled van I've serviced--as in, it's no different than a typical front engine vehicle, except for the rad bleeder bolt. _________________ Casey--

Thanks John and Casey. Ya, as I thought, the expansion tank was quite low yesterday morning (cold engine). Still haven't used all the coolant I set aside to refill the system but maybe the tank is low again today. Really thought I'd gotten all the coolant out by draining at the lowest point. Maybe not.
