My banshee was overheating coolant shooting out of overflow tubes and bottle. I thought the impeller was broke, so I bought a high flow impeller and took it apart. The stock plastic impeller was not broke. I changed it anyway. put it all back together and same thing is happening

The excess fuel is caused by the float levels being out of adjustment. Fix the floats and the dead spot may disappear. If not, pull the slides and then move the jet needle clip down one notch. With due respect, I would put the bike carbs back to stock. :)

It's possible your head gasket needs to be replaced. It sounds like combustion pressure is being introduced into the cooling system to me and the head gasket would be the logical place for this to occur.

How much coolant and water should my 2001phone yz


Sorry I do not know about your yz per se but you should have a coolant full mark in your system coolant bottle and if not over full you should not have any coming out of the overflow line. You might have fluid coming out if you have a head leak into the coolant system though but check first that you are not overfull, the if you still have coolant coming from the overflow tube check to see if the coolant goes down and keeps going down further and further. Then pressure test your cooling system and check your coolant cap.

87 porsche 924s. Cor overheating at idle. Coolant and oil look normal. No smoke. No heat coming out of vents. Replaced thermostat. Still overheats. Seems to have flow but not sure. It seems the heater core...


run the car with the radiator cap off or the expansion tank cap off, which is part of coolant system and is pressurized, not to be confused with an overflow bottle which is not pressurized, and the heater on high. drain some coolant to allow for expansion. look/listen for bubbles. air from the vents should get hot. give it about 20 minutes

Where is the thermostat on a 96 audi a6


The thermostat on most internal combustion engines controls the flow of coolant to the radiator and this is fed into the top tank of the radiator.

The bottom hose is normally at the inlet to the coolant pump.


Vehicles with AC will have two radiators, and even some, a third for transmission or oil cooling but the largest of them will be the one handling engine cooling.


Locate the topmost hose of the radiator and simply follow it back toward the engine and it is normally connected to a dome-like fitting, under which you will find the thermostat.


If you are experiencing overheating though, it may not be a failed thermostat; this can be caused by a radiator blocked with debris, an internally collapsed hose and worst case, a failing head-gasket. The latter can fail in several places and overheating is often caused by the failure of it between coolant channels and one or more of the cylinders. This allows passage of hot combustion gases directly into the coolant flow.


Check the following: the overflow bottle for traces of oil contamination and possible odor of exhaust fumes, the oil dipstick for a milky deposit and when the engine is running, the overflow bottle for bubbles.

I just got a 97 fzr 600 how do i check the coolant level


With the engine cool, locate the radiator cap on the right side of the motorcycle under the fake tank (the real tank is under neath a plastic cover). You may have to take off the right lower cowl. Remove the cap and fill the radiator to the top. Now, take off the seat and fill the overflow bottle to the high mark. You can follow the overflow tube from the over flow bottle to the radiator cap and vice versa. Ride the motorcycle and check the over flow tank level again after the bike cools down .

My banshee pushes coolant out of the overflow


Typically, with this type of problem , you are dealing with a leaking head gasket. Compressed gas and air from the compression stroke is forcing gas past the head o-ring or gasket into the coolant side of the cylinder. The expanding air bubble forces coolant past the cap causing the bottle to over flow.

How to fix a cooling leck on my banshee 350 1990 i need a pic of the moter


go to bikebandit.com and look up yamaha 1990 banshee, they have all the schematics and parts you need. if it's leaking from the radiators, try bars leaks from your local parts stores, from a hose, tighten otreplace hoses, if itcoming from the top end (cylinders) replace your head gaskets/o-rings, if you are getting water in the crankcase oil, you need a new impeller shaft seal and if it's just coming out of the overflow bottle (under the seat) you have too much antifreeze in in or you are overheating fror some reason, usually running lean, too slow or internal engine damage...

best of luck and happy riding

Radiator over flow bottle fills with coolant.


There's nothing wrong with the overflow bottle filling with coolant, that's what it's there for. As long as it doesn't pour out the top it's fine.

Overheating


Have you tried the 8 mm bleeder screw on top of the thermostat housing? You may have air trapped behind your thermostat. Also, overheating can be caused by a collapsed lower radiator hose. If it's soft and you can squeeze it together, then under acceleration it closes down on itself thus preventing the flow of your coolant. Also check your radiator cap. It's supposed to be a 1.1 Bar cap but if it's not functioning correctly, by having to add coolant to the coolant reservoir bottle or the coolant overflow bottle overflowing, usually says it's the radiator cap. These are the simple fixes that you ,may have overlooked.

Good Luck,
