  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

2012 TE449 coolant overflow problem

I used to use Engineice myself and switched to XF. The problem is the water, it eats aluminum and spoils the coolant. Our XF is 26.95/half gallon. Most bikes require half that. I added it a year ago, never have to change it again.

Got my new cap in. Have taken it out for a few runs around the block and seems to have fixed the issue. I will take for longer ride tomorrow to be sure, but seems that it was a faulty radiator cap that was causing my issue. Thanks for the help!
 
Any chance you could post pics of the rubber sealer surfaces of both caps, and maybe press each cap down on a bathroom scale, and note how many pounds are shown when the spring just starts to compress....
 
Having the same problems with my 2011 449 and just been through everything mentioned here. Its 40'c here at the moment and I only noticed the problem after a quick check over of the fluids after a long hot ride. The coolant was down by about 100 millilitres, so topped it up with water to the workshop manual specs (10 millimetres above the cells) and noticed that the fluid was brown and did not look too fresh. The bike has only 800 kms on it and I wouldn't have expected the fluid to be brown and off looking. So did a complete flush, all new fluid and away I went. I hadn't noticed the leak before, I only noticed the levels were down. So then after the flush and new fluid and everything double checked, I noticed the leak (same as described in the above posts). Frustrated by the whole ordeal and wish I had have read these posts before stuffing about for the past 2 days. Oh we'll better late than never. So I'll get on ebay and look for a new cap too, I hope mine is a simple fix too!
 
wonder why they don't come stock with a catch tank, even a very small one? wrf/crf/klx/gasser & others do. is it because ktms don't so its not cool? you cant tell me theyd add much weight. first thing id be doing with a hot running big bore 4T! either that or run 2 fans, 1 each side. odd they dont:confused:

True!
 
The XF works. I have not had a drop of overflow. My fan works, but it comes on later.
Since then I have added a 2nd fan on other radiator. I only turn it on running single track.
I think it might help in 2 ways (not sure) 1. Bike gets cooler. 2. That 2nd fan running on top
of coolant temp sensor maybe makes bikes ECU see cooler, run richer? Maybe?
 
Bit of an old thread I know, but I had an issue with my TE449 being low on coolant.

Manual says it should be 1cm over the fins, but everytime I filled it, it kept emptying so that it was level or below the fins.

No apparent signs of leaking, and the bike is only 6 months old and not been thrashed.

A suggestion from my local dealer was to apply some grease to both rubber seals in the rad cap, which will help it seat properly on the seals.

Tried it, and after a 95mile ride yesterday, coolant still full.

Happy days :D
 
The problem is the water in the coolant, not the coolant. Water has too low of a boiling point to be a practical coolant. Maintaining pressures 30psi or more is very difficult to do. Waterless coolants operate at low pressures, 0-7psi typically. Plus doing away with the corrosive nature of water that kills radiators and head gaskets is good too. :)

XF2 Coolant
 
no issues on my side with the cooland. I use Radiator ice now , but used to have after the first Factory coolant flush John Deere Engine coolant in it. Works a tread.
You just need to make sure you have that Radiator going or it will boil. This Engine heats up quite fast without airflow going through the radiator.

I did have one problems with my Radiator cap , but only because i smashed a radiator off and replaced it with a RAdiator from a 2011 model. But used my 2013 Radiator cap. There is a difference in the neck hight which made the radiator leak.
