I'm finally back to continue......
It's been busy.
I'm hoping I can do some sort of flush without pulling the radiator. Maybe the Downy will do the trick. It just kinda seems right on the edge and hasn't done this before. Even when I was pulling a trailer with a '51 Chevy on it, it didn't overheat.
I know my temp gauge is not right as I put a mechanical on the motor back in the engine compartment. My dash gauge registers it a little hotter than the motor is, but not sure exactly how much. Jerry Lieber had shot my radiator last fall, at a rally when I just pulled in, with his infrared gun and it showed between 165 and 185 (I'm pretty sure) depending on where he took the reading on the radiator (top/bottom). I understood that to be ok.
I should probably get one of those guns.
The splash guard/skirt/mudflap/whatever you call it under the bus that causes the negative pressure is still on my bus. It's in "pretty good shape" except for about 1/4 of it is missing from just the center section. (not much) Maybe it would make a difference to replace that center section.
By the way, is it better to be as close to the ground as possible or is there a point where it doesn't really matter? I'm probably going to create a flap myself from belting.
Better yet add a deflector below radiator’s grille with heavy rubber flap material or longer bottom “tunneling” shield to increase greater vacuum after fan. Some of newer high end bus conversions come with that feature.
Any chance someone could explain this a little bit better? I'm not sure I am quite getting it. But it sounds like something I could do and it could help.
Say how fast are you going when it starts to get Hot?
Wish i knew. No speedo. But I can tell you, I wasn't passing anyone. Maybe 60-65 max. I also have the V730 tranny. I think it was an upgrade at some point. (It has the wrong speedo linkage and it was missing the side mounting bracket that I built for it.) I'm not sure about the oil to air heat exchanger. What's it look like?
Here are a couple shots so maybe one of you can tell me what I have or don't have.
(I love the wonders of modern technology!
So what is the fan drive? The "cone" that the fan is on? Can you tell from the pix what I have? (Hope so.) If not, I'll get you more.
Hopefully you guys can address this from what I have posted. I need to get this figured out soon as I am taking a trip July 3rd. I have my deadlines on my latest projects met pretty well, so hopefully I can put a little more time into this effort.
Thanx for ALL the help!!!! ( I was telling a buddy the next thing I need for the bus is a Lap Top for when I am on the road!!! I am ALWAYS singing the praises of this board!! Told two guys today already!!!
