Has anyone seen a bus with A/C installed? This bus had A/C at one time. I think maybe that bashed in heat tube is related to the removed A/C. Thoughts?Hippie wrote:That looks melted more than bashed.satchmo wrote:

Too late. New oil cooler is already installed. I haven't put everything back together yet (gotta fab those little swinging doors at the bottom of the fan shroud, cut out some gaskets, paint some tin, find some brackets, etc, etc). Maybe I will do the experiment you suggest in reverse since I already did the oil cooler and gasket.SlowLane wrote:Tim, if you have the time and inclination, can I suggest an experiment?
Before you dig into the motor and replace the cooler and its gasket, do a quick oil change to 10W30 and see if the high temperature problem persists. Then do the oil cooler swap / gasket install and see how much of an improvement you get.
I think you hit the nail on the head there. That area is pretty much the only place you could mount an A/C compressor.This bus had A/C at one time. I think maybe that bashed in heat tube is related to the removed A/C. Thoughts?
Tim, when I did those oil temperature tests with RandyInMaine's vdo oil temp gauges, it was about as hot as its been around here lately, 100's.satchmo wrote:Got the new oil cooler installed after cleaning up the seal seats. Gasket at the tins replaced too. I filled it with 20W50 oil and will do some test drives this weekend. I hope the oil temp stays under 230 for extended highway trips.
See for yourself how the CHTs respond quickly to the mixture at speed.satchmo wrote:very high idle condition when the engine is this warm
I know it is on the lean side since plugs were quite white.

The oil temp sender is: SEN-04-3 - Oil Temperature Sender from Dakota Digital, tied to one of their Odyssey gauges. The temp is taken at the bottom of the taco plate. I know DD CHT gauges are considered better, but not sure about the oil temp senders. The CHT is about the same after the swap, but the oil temp is higher.
