In line coolant heater

[karlburns]

Has anyone put one of the in line coolant heaters in their viper? If so does it work on really cold night like it does on Apex and vectors?

Trying to figure out a way to not have to worry when it's -50 next winter.

No ones tried this? Or if i went and looked at the sled would I realize this is a dumb question?

Looking at yamaha accessories I found this for the vector and apex maybe just a matter of time before it's available for the viper

Yeah that's what I'm talking about. I have one on my apex and vector works like a charm. Is the Vipers coolant hose larger and therefore it wouldn't work?

I figured someone on here would have already tried this and could post the results

The Viper is a Cat Procross chassis, so you could try looking on their site.

I've not tried a -50 start and even if it did start I don't think I'd be inclined to ride, but I will say I think a simple battery tender would do well and less hassle?

I wouldn't choose to ride in -50 but there's been several times I've had to. The problem with a battery tender is it wouldn't provide any heat to the motor. At -50 those engine blocks are not happy to be turned over. Ate my starter and stripped the gears. Trying to avoid a repeat of that.

Also I'm aware these things are very hard on starters thus I'm surprised no one has tried this yet.

Try member Yellowknife. He had a Viper and I'd bet money he had an inline coolant heater installed. There has been a thread about using a capacitor to insure that the voltage at start up is high enough to keep all the electronics happy, particular to Viper guys. At those temps I hit mine with everything ... coolant heater, jumper pack and a tarp over the engine with a small electric heater for a while. That tarp is a big deal, I think because it warms up the electronics/sensors. Note my sled is not a Viper.

Yellowknife also posts videos and there is lots of footage of his Viper starting woes. I think the only good thing he has to say regards his Viper is 'Sold' but there are lots of guys on here who really like them.

I like the ride when it starts. Starting it is the only complaint I have. When it ate the starter (original with 3000 miles on it) I had the sled hooked up to with jumpers to my truck to make sure it had enough juice.

My usual start problem is the stupid oil light being on despite the thing being full.

Does anyone know if the vipers coolant line is same I/d as apexs and vectors?

Found it on the Cat website. It's for the Bearcat 7000. Could fit the viper?

Check the accessory catalog on the Yamaha Web site. The heater comes up when you select your ride.

Should be pretty straight forward. I have used one on my nytro for years. Since its the same engine (viper/nytro) the coolant hoses ought to be the same dia.

Works great. Engine is toasty warm when I go to turn it over.

You Can Install it but it goes to your heat exchanger first then to engine, so at -30C no good.

An in line heater has nothing to do with circulation of fluid. As it does not circulate fluid. It is just a heating element. Just like a block heater. The best way to do it is place it as close to engine as possible and to plug it in after the day's ride . That way it doesn't have to heat up Preston from dead cold.
The heater used for Nytro and Apex. Should work on viper and SW. As hoses should be same size.

My theory would be to tap the starter for a couple seconds every hour for a few hours to rotate the coolant. Assuming there's a pump that should get it rotated a little bit.
