1330cc My 2014 RT is Over heating - any ideas on how to correct?

[BLUEKNIGHT911]

Mike.. Who has aftermarket grilles for the F3?

For F-3 I don't know ….. for RT there are a few choices, I made mine using the OEM grilles. I moved them forward in the opening and made them easily removeable ….. Mike hyea:

the fan kicked in at 235 degrees as it should and the temp never got over the 1/2 way mark.
I was just wondering if anyone else had a problem and what could be done to get the bike to run cooler.

That is perfectly normal. The other things that happened are NOT.

You don't WANT the engine to run any cooler; that is the point where it was designed for.
Keeping the heat off of the rider is an entirely different problem.

Alas, I think you might need to be near a dealer when this happens to figure it out.
And you should be ready to do some quick checks yourself......like being sure the fan is running right and being sure that coolant isn't spewing out anywhere but the overflow.

Intermittent problems are a bear; especially when some of the suspected components are hard to test.......like the fuel pump.

I assume that you are now checking the coolant level often ??

Yes.. I do check the coolant level and never have it spew out of any place.. never seen anything under the bike to indicate the loss of any fluid.

Good. But those are two different things. Sometimes fluid loss ONLY occurs when going down the road.

That probably eliminates the pressure cap. But there still is the thermostat and pump.

Wifes 16 F3T went into Limp Mode after 20 miles down the Interstate last evening in 100 plus temperature. She said that the temp bars were one blank from the top, but she was able to run 50 mph in the right lane for 2 miles to get to an exit. When she got off the Interstate, she let shut it off for a few minutes and then restarted and rode the rest of the 12 miles home on secondary roads with the temp bars in the middle. When she pulled into the garage, the fans were running constant.

This morning I took off the grille, and front wheels and unbolted the fans so I could clean and back flush the radiator fins. I didn't see a lot of obvious bugs or butterflies, but a spotlight showed that light was impeded thru the fins.

After vacuuming from inside, using and air nozzle from the sides,,I soaked with various cleaners, backflushed, blew out with the leaf blower, and repeated three more times... I can now see light shining thru the fins...

Even though the radiators were not visibly plugged, fine grit, crud and guts seem to have built up over the three years and 47,000 miles. The hardest part was getting the fan mounting nuts off in the rear of the frunk.

I had similar problems on my F3 with overheating at low speeds the dealer tells me it was a bad manifold allowing the motor to run rich causing a overheating problem it’s hopefully fixed picking it up tomorrow about a $750 fix thank goodness for extended warranty!!!

Well.. my over heating issue is getting worse..I had the cooling system flushed and my mechanic recommended Engine Ice coolant. I went ahead and had him replace the original coolant with the Engine Ice. Yesterday I went for a 100 mi ride with friends and all was well until we stopped for a few minutes on the way home. Got on the bike and temp was fine within a mile the fans were on but the temp bars were at 4.. so normal. Kept going and all of a sudden the temp alert icon lit up and of course the bike just about stops in it's tracks. I cranked on the throttle (one dealership told me to go faster when the bike was overheating) and the bike balked then jumped and the temp went down to normal. I rode the final 20 miles home with out an issue. So today I get on the bike to go and run a few errands and before I got 1 mile down the road the high temp light went on. I am guessing that the thermostat is the issue as the temp just jumps up and then goes right back down to 4 bars. Any thoughts?

If it cools when its moving at speed, but gets hot while at idle, it is likely an airflow issue not a thermostat. My first thought would also be dirty or clogged fins as others have mentioned.

It doesn't get hot when just idling.. my mechanic had it running for 40 minutes and no temp spikes at all. I will check out the rad fins but they look clean from the outside.

If it is a thermostat, know that this is NOT an inexpensive fix. The thermostat and water pump are both one unit. My bike is in the shop now for a stuck thermostat and the dealer quoted me close to 1K for repair except mine is being covered by warranty. Another engineering genius from BRP..... Jim

$1,000 to replace a thermostat! Ay carumba!
:shocked:

I spend $630 to replace my water pump and 5000 miles later, everything is running normal. no more overheating :yes::yes:

OK.. here we go again.. Had the shop replace the water pump, thermostat and temp sensor. They also purged the cooling system. Picked up the bike and within 1/4mile the bike overheated. Turned around and went back to the shop. Left the bike running and still showing HOT. All bars and high temp icon on. Service manager got on and rode it around to the back of the shop and in 100 feet the temp dropped down to normal. He rode it around on the road for about 20 miles and could not recreate the issue. Checked the engine temp and temp around the rad hoses with laser temp gun and all is normal. Gave us the gun to take home in case it happened again. No issues on 90mi ride home. No issues the next day on 150mi ride. Bike sat for 3 days and when I got on to take it to gas up before a long day trip (400mi) it showed over heating in about 1.5 miles. Stopped and checked all the temps and all were normal. Even the rads were still at ambient air temp. Filled up with gas and on the way home the temp dropped to normal. All of this happened within 5 miles of riding. The service manager says there is no way that there is an air pocket in the cooling system. He doesn't have a clue so is going to contact Can-Am and see if they can give any insight. Anyone care to make a suggestion of what else could be wrong? :banghead:

I've got a 4th gen Camaro, LS1 these cars are notorious for being extremely difficult to get all of the air out of the cooling system. Very similar to the Camaro symptoms of not getting them purged completely. I'm not sure how difficult these are to purge but this started w/ a low coolant level, and when the svc manager took it at low speed around back it could have passed a bubble and started cooling...
