  • 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 The previous version was outdated and no longer supported.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!

2008 TE 510 OVERHEATING ISSUE

The scenario:I took the 08 out last weekend for some NNJ trail riding. I use the term trail, but really it was single track, giant technical up and down hills and tight woods. Normally I would take my cr250 that gets set up for hardcore riding and ice racing, but I figured since a quad was going how bad could it be. Plus, I've been loving the Husky so much, I never changed the ice tires to dirt. Outside temp was about a million, a nice humid heat.

The problem: I never had a problem on the street or fast fire break riding.The bike over heated all thru the day.Mostly during all the slow, hard parts of the ride. Most of the time never left 1st gear. I kept dumping water into it just to get out of the woods. Hoping I wouldn't heat seize or blow it up. I never had a problem on the street or fast fire break riding.I am new to all the technology with this bike, having ridden two strokes and older fours. Oh yea the bike was not covered in mud.

My solution: I will be going over the whole bike today. Change oil,filters, coolant (using ENGINE ICE, this stuff works well.)

The questions: Has anyone had a similar problem and found a solution? Is there a method to test when the fan kicks on? What do you think about an overide switch for the fan for extreme heat conditions? Would it even make a difference?

Any input would be appreciated. Thanks
 
The fan coming on reliably is the #1 issue that will heat up a bike. You may have a bad temp sensor, have you seen your fan coming on, was it on all of the time on the trail?

I had to get real familiar with my bike's temp and when the fan comes on, and it will come one at different temps with different sensors. I use an infrared temp gauge and I put the laset on the breass coupling of the WTS (water temp sensor). The first sensor I had, the fan would come on reliably at 220f. Then I had to put in a new sensor, and another one, and even a 3rd one and this newest comes on about 210f.

How many miles on the bike? Youo'll need to try and monitor the amount of rad fluid and see if any is missing at the end of the day. Coolant that goes missing could mean a leaking head gasket, I had one of those as well.

The bike only has 1400 on it. I like the infrared test , I'll give it a try. It makes sense about the fan not kicking on during low speed abuse and over heating. So I guess there is no way to get a temp sensor pre set for the factory operating temp? Which I have not looked up yet. Have to say I love the bike, but between having to heat shrink every connector and water proofing other weak spots to avoid being left dead on the trail because of a puddle of water. And now the over heating problem, starting to think about how much maintenance and prep this thing needs just to ride for a little while. I'll give it another year to work out the bugs and get dialed in for reliability. Thanks, I still owe you some pictures of the water proofing I did.

Just get a couple of OEM WTSs (I keep a couple on hand) they are $15 apiece, they are pre-set to start the fan somewhere around 210-220f water temp. Use the thermometer to get to know your system, so that you know when it comes on, I look down at the fan when I get to the gnarly trails and make sure it is running. When my fan has been working, and I haven't had a head gasket leak, I have never overheated on singletrack trails.
 
Thanks, that gives me a bit of confidence. Just changed all fluids and let it idle. Definitely have a leak. Have to pull tank to see if it's the top hose or the radiator itself. Once I correct the leak, I'll double check the fan. You maybe right about the sensor. I don,t think I had a leak before the ride and I didn't dump the bike. May have over heated from the fail temp sensor, built enough pressure to develop a leak. Hey thanks again. PS. Being made to reenter society from the garage to go to a pool party. Have to fix her up in the morning.
 
there is a high performance water pump kit avail from Husqvarna.it is a little less than $50.i am sure it would help and is good bang for the buck.dan
 
I would check everything cooling related, my '09 TE450 used to boil over in tight steep single track when hot outside even with everything working properly. I've got a water temp gauge now to keep an eye on the temps and switched to Evans http://www.cafehusky.com/threads/ziptys-xf-radiator-coolant.31244/ it will not boil over now but with the Evans you could run the risk of heat related issues and not know it.

Also, I'm installing my second high performance pump, I just found the impeller a little loose on the shaft, not spinning on the shaft but getting ready to...
 
Thanks all. This whole issue is my own fault. Everyone knows when you buy anything new or used, you have to go over the entire machine. I failed to check everything on this bike. Any way, the right radiator must have been replaced at one time. The upper hose clamp was loose and was leaking. Fan works fine. Going for a test ride now. Lesson learned, no matter how much prior owners seem to be on the ball, you never know their abilities when it comes to repair or maintenance.

I am still going to invest in the h.p. pump just for some added piece of mind. Thanks again
 
The oversized water pump is a very worthy upgrade. You can also avoid some woes down the road by picking up the upper radiator hoses from a 2010 450 or 510 (8000 H1410). They eliminated that plastic T fitting, which can melt through at the worst times.

Glad you got your issue worked out quickly. :D
