Full Floater Posted August 9 Share Posted August 9 https://wattstruckcenter.com/shop/heater-ac-unit-for-r-rw-cabs?search=heater Has anyone run these? I'm looking at upgrading my factory 70's R heater in one way or another. I was thinking of either installing an aux heater somewhere, or installing this box. Does anyone know if the heater output is greater than the stock units? I don't run a/c, its strictly the heater that im after.

67RModel Posted August 9 Share Posted August 9 Well that looks like an identical reproduction to what is in my 94 RD and it will boil me in there if I need it too. Usually have to have the window rolled down a few inches if its on. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556752 Share on other sites More sharing options...

Usually have to have the window rolled down a few inches if its on. This is the kind of stuff I was hoping to hear. My heaters in my trucks (all 70's vintage) are sub par at best. For both heat and blower force. Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556756 Share on other sites More sharing options...
Popular Post mrsmackpaul Posted August 9 Popular Post Share Posted August 9 I dunno how good they are, I imported one to Australia a couple of years (maybe 5 if I think about it) for the AC The R model cab really boils me alive, but to this day it is all in boxes waiting for me to get my priorities right I read about on here that these provided the best in cab cooling for a factory fitted style look Now convert that price to Aussie dollars, then add a couple of gorillas for freight And think I have to cut it appart and change it all to make it RHD, I really am a idiot Just as well the Princess doesn't read this forum 😉 A good mate of mine and myself argue argue about which of us is the bigger idiot His wife reckons we are such idiots she made us tee shirts IIdiot "I" and idiot "II" Australia day a few years ago Paul 2 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556759 Share on other sites More sharing options...

mowerman Posted August 11 Share Posted August 11 Yeah, I’m not sure what your issue is. I’ve had very good luck with R and U model stock heaters Open the cowl … and you don’t even need the blower.. good luck… bob Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556840 Share on other sites More sharing options...
mowerman Posted August 11 Share Posted August 11 Your heater core might be blocked full of leaves or maybe coolant is blowing through it for some reason.. at any rate, it wouldn’t hurt to just switch it out and I said good luck bob Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556845 Share on other sites More sharing options...

I've had the boxes apart and confirmed no blockages or debris. The heater does fine, until maybe 10 below Celsius. Just looking for something better as I do spend a good portion of the year below those temps 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556851 Share on other sites More sharing options...
Geoff Weeks Posted August 11 Share Posted August 11 when it is cold outside and the heater is not preforming well, grab the inlet and outlet pipes, if one is cool and the other hot, the core is plugged and needs to be replaced. They both should be about the same temperature. Also, if used the water control valve can reduce flow, make sure it has good flow in the circuit. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556855 Share on other sites More sharing options...

The engine also will run up to operating temps no problem. The blower motor is good. Just need more during the colder times, of both heat and blower volume. R model defrost vents are not the best to begin with, so the far reaches of the windshield always fog up etc. Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556862 Share on other sites More sharing options...

Full Floater Posted August 12 Author Share Posted August 12 Ya this is the style of box that I have. The switch between floor and def is definite, and there is no lingering air movement in the opposite position as to what is selected. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556922 Share on other sites More sharing options...

mrsmackpaul Posted August 13 Share Posted August 13 A good thought there, I was working on my IH farm tractor AC and put the drums of the fan on backwards I know, what a dick The fan shifted air, not a huge amount though, and was loud to boot Put the drums on the correct way and it was a changed tractor Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74444-watts-new-heater/#findComment-556951 Share on other sites More sharing options...
