Thermosstat

Hey Jerry, just sent you a PM but yes, that's the part. Not 100% sure they are interchangeable since I've never done one and don't know anyone who has... Yet.... Lol. Good luck and keep us posted on how it all works out.

Hi DrewNJ,

Re: just sent you a PM

I just PM'd back at you.

Yes, I will keep everyone posted on what, if anything, happens.

I am in the midst of a serious heat issue on my 2010 RT. Case in discussion with BRP and not sure where it is for sure yet.
The RT ran three to four bars at all times, summer and winter (I am a year around rider). then about the end of last year it started running a lot hotter and then got to touch the side panel the frame under the seat or the gas tank. Long story form there to now and I said, not sure what BPR is going to do.

The tech had a different idea about the over heat. He wondered if those bad hoses were contributing a super lean, very hot cylinder. then I read somewhere about a ECM (??) electrical redo of some kind. Anybody got any ideas.

If you want to consider installing a lower rated thermostat look here ( and I do NOT know if they will fit at this time ):

I am only offering this info for you to consider, I am not endorsing do it.

Hi folks,

Re: Yes, I will keep everyone posted on what, if anything, happens.

I am going to need some coolant once the stat gets here. How much cooling liquid does the '08 Spyder take? I would guess that maybe I'll be draining almost all of it out while doing the stat changeover.

Thanks to all you shade tree mechanics in advance,

Hi to all of you shade tree mechanics out there,

My Spyder seems to love 5 bars on the temp guage. Today ( a warm 86* ) it got to 6 bars.

Is there a lower temp thermostat that can be put in to keep it running cooler?

Jerry Baumchen
Too lazy to look it up somewhere

When was your coolant changed. If it's over 2 years, change it. I change my own and I use Prestone premixed 50/50 and I add 5 ounces of Redline Water Wetter to the 1 gallon 50/50 premixed . My Spyder RS-S SE5 runs less 5 bars in the hottest weather. If your still have a problem PM me.

Hi Mike,

Re: If your still have a problem PM me.

No problems yet as I have yet to start this effort.

I did just PM you for some more specific info,

Thanks,

Hi folks,

Re: No problems yet as I have yet to start this effort.

Well, an update. The 75* C thermostat came in but it would not fit. The opening that is for the hose from the engine to the stat is smaller on the Aprilia stat; ~ 25 mm for the BRP stat vs 18 mm for the Aprilia stat. I could do some Rube Goldberg reworking to get it to fit but the concern is that the smaller opening would reduce the coolant flow; and that is the wrong way to go to reduce the temps. Plus, that would be one more thing that would go wrong somewhere a couple of 100 miles from home.

So, I ended up just changing out the coolant ( Thanks DrewNJ ) and I will be returning the parts.

I doubt that I will spend anymore time on this effort; unless something new happens.

Damn....that sucks. So close!!!

Just thinking out loud. .....if the smaller end is on the bypass side from the motor the size wouldn't make much difference, as once the stat sees the temp it's going to open. As long as the radiator/engine sides are the same I'd think it would be good????

Hi DrewNJ,

Re: ....that sucks. So close!!!

Yup. If I were 40 yrs younger I would had a go at it. But, not anymore; I want to avoid potential problems, not create them.

It was tempting but a motorcycle broken down on the side of the road is a different animal than a car broken down on the side of the road.

PS) I actually did go to NAPA auto parts and bought a short section of rubber hose to increase the OD on that opening so my Spyder hose would fit. I eventually decided that it was just too Rube Goldberg for me.
