Quick question...The 'insulation blanket thing' i have which runs under the van for the warm air tube is looking decidely 'ragged'.What have people on here used as a replacement 'jacket' if you will. Can i use that 'silver bubble wrap' looking stuff?
I've used the silver bubble wrap type stuff......not had a chance to see how effective it is yet be carefull of that original insulation, I took mine off and it looked like asbestose to me, others said it wasnt.....but I'm pretty damn sure it was.....so ware a mask and damp it all down.....it does crumble to dust as you remove it
Interesting...in that case,can i make a new one by wrapping glass fibre around the heater tube,and then wrapping the silver bubble stuff around that as a 'jacket'? (held by equally spaced cable ties?)...
Seek out some OG heat exchangers and don't bother with any moisture trapping insulation. I can drive mine in a snow storm and stay warm - no isulation on any part, but OG heat exchangers.
^this. My underbody is naked (no belly pan) and once the engine's warmed up, it's hard to hold your hand over the screen vents, the air's so hot.
The problem most buses have with the heating, other than leaks, is not that the air from the exchangers is cooling down on it's way from the heat exchangers, it's that it's not very hot in the first place.
I have og heat exchangers and they are fine,they are just in the garage,not on the bus.I may put them on, but i have to drop the engine in the winter as there are two bolt holes i need to helicoil,so i may put them on then. I am just thinking on how to make a better jacket for the heating tube.It wont rust anyway,as it is galvanised.
i have the original card tube thing and i've sleeved it with a metal pipe that's used on boiler flues etc
I still need to fabricate a 'Y' piece...Im sure i can make a better job than those fibre glass things i have seen...i just havnt turned my mind to it yet... ...
