Curious if there is a way to test/verify the cooling system is holding pressure? I’m not familiar with the D6H setup; but I suspect it has to build/create some (probably low like 5-6psi)?? My understanding is with no pressure you are going to get higher temps.
Never mentioned- but no leaks, or required “tops-offs” needed with the antifreeze/water?
I will admit that belt track furthest in on the pulley does look like the V is quite worn, but I don’t think that’s “the” issue (and tough to tell 100% from pic).
When you had radiator out, did you happen to check if there was/is any scale/build up on the lower line/hose going to water pump? Seems highly unlikely, but you’ve checked so much I’m surprised you’re not seeing an improvement.
While your fan appears in correct orientation, does it have all its blades??
Have you tried running the machine with one side panel off to see if more airflow would help? Or on the flip side, are any vents covered over that would restrict airflow??
also post up a pic of the whole machine (please), I’d like to see the rake it’s pushing around!!
Wish I had the silver bullet, but keep after it, you will figure it, or modify it to make it right!! ; )
Hi D5Dan thanks for the post and thanks very much for the encouragement.
Sorry for the slow response, that saying “Burning the candle at both ends” doesn’t really cover it… more like the whole bloody candle is on fire at once here lately! Haha
some good suggestions!!
The radiator cap was one of the first things I changed back when I first got the dozer, but that was a long time ago now and could need doing again! I’ll order one and put it on and see. It seems to hold pressure but I haven’t actually tested with a gauge. We are going back up today so I’ll see where we can connect a gauge.
No leaks and doesn’t need any top offs everyday or anything like that. Occasionally it might be a little down but it doesn’t spew out the overflow when it’s hot. Sometimes when it’s been hot it might sweat at the overflow enough for dust to stick around the overflow. I thought this was pretty normal considering the temps.
The pulleys do have a bit of wear but I don’t that’s the drama either. I have seen a lot worse still doing the job….. but I am happy to be told I am wrong on that too.
No I’m sure I had the bottom hose off the water pump to flush it and it all looked good.
Yep all the fan is there.
I’ll try to remove the sides panels to check for any improvement. I had tried it before when I still had other problems but not this time. I actually found an old thread where “Scrub Puller” had said about having issues with the hot air from the radiator hitting the back of the Stickrakes and recirculating too. They made deflectors to push it upwards. I’ll post a pic of the machine for you and see what you think.
