Overheating

I know this has been a popular subject . Ok here is what i have . While doing some cleaning i noticed i had a wore spot in my drivers side rad hose. So i changed it. Ever since then rhino gets hot and spits out overflow hose. I did NOT bleed the system . I just added water & anti freeze back to rad. I am thinking i just need to bleed it but not positive that is what is wrong.

Yes, bleed the system!

It helps if you fill out your profile so we know what model you have.

The 660 has 2 bleeder screws, one one the head and the other on the water pump.

I agree, you have to bleed the system.

Sorry , i updated my profile . Its a 06 660 . I am thinking thats all it is since it didnt do it before i replaced hose just wanted to make sure. Now i jack front end up fill radiator with cap off start it up let it run open bleeder and keep rad full ? Is this the way to do it ?

You can jack it up if you want, start it and crack upper screw until you get a steady flow of coolant.

Where was your worn spot on the hose? Where.the engine cover hits it? If so, trim the inner lip on the cover. I've seen a lot of the hoses rub in that area. Yamaha did add a sleeve on the hose but it still hits there.

i never run mine while bleeding them..anti freeze expands when as it gets hot so you wanna fill it cold..

ok so i should fill up rad engine cold & not running , open bleeder on top of water pump housing ? The hose actually had a wors spot from the front driveshaft . It looks like there was a holder that wasnt fastened or the hose had worked loose from it.

bled the system and seems to be good !

This stuff and Engine Ice both work great but are both expensive and a pain in the ass to run. You can't mix it with water so you're forced to carry a jug with you at all times...and where I live you can't buy it anywhere. I ran it last season but flushed it this year because of this.

I just use dexcool

my fan stopped working so I replaced it with a new fan with a shroud. never bleed or burped it. and never overheats now. when I got the new fan it ran backwards blowing out the front. Had to cut wires and reverse them. it was strange. maybe the put the connector on backward at the factory

had to bleed system when I installed my heater no over heating problems
