coolant

Hi all, I have a slow annoying leak from from the "drain cock" I can see in the schematic there are several o-rings and maybe a valve in there? Babbits shows it all as one unit for purchase. Do you know of what size o-ring these are so I can replace or where to purchase? Or maybe its something...

Hey y'all, This is the first time I've experienced this issue with any bike. I had a leak on a crankcase cover on an FZ. Gasket was super easy to replace. It looks like a major PITA on the VMax to replace the head gaskets. It looks like I'll have to take the carbs off for sure. Coolant was...

Well, there are new hoses, new thermostat, drain cock assembly, the only thing thus far that has not been replaced are the sensors under the radiator cap thingy and radiator cap. Now, as I run the bike, the black overflow tube is pushing coolant to the catch tank and draining out. I can...

Hi everyone! I have an issue that started through the winter. First had a leak at the drain valve. I now have a new OEM tube installed. Now there is a leak where the tube goes into the engine block. I replaced the old o ring with a new one. The new o ring is a bit fatter than the old but didn't...

Hey guys, Just need a coolant bottle cap for a 1200 V Max 1989. Just a cap needed, let me know if you have one for sale? Thanks

Started dripping at the elbow joint lower right side. This is the tube that connects the engine to the radiator. Happened in Colorado on my trip. We put aluma seal in it along with a McGiverish section of bicycle inner tube cut to size and a hose clamp. Got home ok, but need to get an idea...

Hey Guys, You know that coolant tube that has the pet cock valve? It has a 90 degree angle in it, that leads to the lower thermostat housing? While trying to put my radiator back on, after installing my replacement mufflers / headers, I noticed that there is a single bolt that looks to be...

Getting ready to change coolant. Started searching for how-to's since the service manual pics leave something to be desired. Came across a pic online that says the position shown is for draining the radiator...which is interesting because that's the position it is in right now. Bike runs fine...

Trying to bring to life an 85. The gas tank is a little rusty so going to get that cleaned up using some of the suggestions on this forum. However, before I did that, I planned to fire her up by running fuel lines to an external tank. I decided to check the coolant and found this white/yellow...

Hi there ..My name is Manny im from Costa Rica....i just rebuilt the engine on my 1995 VMax ..(i bought only original parts) and a couple of weeks after i start riding on it , i found some oil in the coolant tank ...put a new water pump(i thought that was the problem)and clean all the oil out...

THEN all hell broke loose literaly... 97 vmax 24k...bikes been running tops for two weeks Ive had it, no leaks at all of any type. The coolant was old and piss looking so today I flushed and toped off with Prestone premix went for a sprightly ride and all was good. Fast forward 4 hours later...

Like the title says I replaced the coolant hoses on my 98 vmax as they appeared to be original and were pretty sketchy. Bought some made in China silicone hoses as they were much cheaper than oem. Seemed to go well but I saw a drip at the large hose at the bottom of the radiator where it goes...

Aloha guys. Well, I just rebuilt the motor and it was running fine. On the first ride, saw the weep hole was leaking....so i rebuilt the water pump. Weep hole is good now. Filled her up with coolant and started her up. Got her hot and fan kicked on. I noticed some coolant on the ground right...

Hello all I need your help here! I have a coolant leaking from that hole from that locate on the cylinder. That hole is located inside the middle of the aluminum line (the are three line of aluminum on the head) What is that mean? I got this bike a month ago from USA so I only drive on it...

Disregard, Figured it out da-herk!!

Hello, My vmax started leaking coolant from the drain valve and I was wondering if there is anything special about fixing it. If I take it apart what will I need to put it back together? Thanks

We've had a week or so of 100 degree weather. I ride EVERY DAY in Los Angeles to and from work (for the past 22 years) but I especially noticed the bike running hotter than usual a few late afternoons last week, and some overflow from the down-tube of the coolant reservoir dripping beneath the...

Hello everyone Well today I finished hooking all of the connections up and fixing 2 coolant leaks after installing my engine with an upgraded trans. Took it for a ride everything went well until I pulled into my driveway. Coolant running out the front.:bang head: Upon inspection I found the...

I bought a 95 V Max a month ago. The bike is stock with approximately 35k miles. I filled the coolant system and i pukes a little coolant out the overflow tube, when the engine is at operating temp. The overflow reservoir doesn't fill up or go do down in volume, coolant just comes out the drain...

I noticed a small coolant leak on the right side of the engine above the foot brake. It looks like a small round hole on the casing. Hole is about a 1/8 or less. It looks like it is supposed to be there, but I noticed a little coolant spray on the exhaust. Anyone have similar issue or can...
