Cannot Bleed Coolant!

just throwing sh*t out there, you never know...lol

I appreciate it. The anticipation to start the motor and then the frustration with trying to bleed it may have caused me to over look something. Like you said, you never know. Thanks, G.B.
 
humm, i just rubiult my engine and had no problems bleeding it, even with out the carb heater bleeder. I just leeve it sitting normal fill till the fluid poors out the rear bleed screw then raise the back till it is about 2 inches below the reservoir. Then I fill it till the fluid comes to the bleed screw. I slowly lower the back till fluid squirts out. then i put the bleed screw back and add more fluid. Done.
 
Well I am making some progress today. At the suggestion of theblues, I removed the hose clamp for the right side rear heat exchanger hose. After removing the hose clamp I burped the hose and a bunch of air came out. With the rear of the sled in the air and after running it a few minutes, when I removed the rear bleed screw I got coolant to shoot out. This is the first time that has happened. I did this twice and then raised the front end. After running a few minutes I am still not getting any warmth in the heat exchangers and the temp light will come on. I cracked the bleed screw on the head and no coolant came out or do I see any.

I am not sure what I want to do next. I think I am going to run out and see if I can buy a new coolant bottle cap at the auto parts store. Maybe I am not building enough pressure and after 7,000 miles my cap is shot?????

I am about to give up on this thing. I am not getting recirculation to the side and rear exchangers. Can anyone tell me what direction fluid should go when I pull the thermostat and the thermostat housing cover and turn the motor? I need to tell if the water pump is working.

Thanks, G.B.
 
G.B. Tell me all that was done to the sled...engine freshen up, new rear exchanger...what else...not to insult you, I have to ask...did you pre-filled the rear cooler to see if it was plugged or welded shut, yes it can happen...or...did you plug a hose with a rag or anything...if you did tear into that engine, did you put on the head gasket right...check the sensor plug, they have a tendency to break right at the end setting off the light...you should be able to see the coolant churn up in the tank by placing a flash light behind it...what is your mix, don't mix it more than 60/40...At this point I would look at getting a rad pressure tester & pressurize it to 15-20 psi, loosen a few hoses here & there to see if air is coming out, work right to left...then add the coolant to it & keep at it, you'll get it...I only had one that was that difficult to do...cheers

Coolant usally goes out the thermostat and around so it should be flowing clockwise!!!

Right daman, I should have said the mag side then the rear & over to the pto side & up to the head...

I will check the head gasket. I remember seeing a small tab sticking out the back of the #1 cly (PTO) under the carb valve.

I did not pre-fill or test new rear cooler. It is a new cooler, never been used.

I am using a 60/40 coolant mix per the manual.

I have never seen any coolant movement in the tank when the engine is running.

I did use a few rags and paper towel in the end of some of the hoses during tear down. However, there was always a couple inches the paper or rag sticking out the end of the hose. I have been thinking about this, but I am fairly certain that I removed all of these before re-assembly.

Thanks, G.B.

daman,

So if you are looking at the thermostat housing, there is a hose going straight down. Does that hose go to the right side exchanger or is to the water pump? If it goes to the water pump then coolant should fly out if I turn the motor over: right? I think it goes to the water pump. If so, does the coolant recirculate through the engine only until the thermostat opens? Then once the thermostat opens coolant flows to the exchangers? Does this make sense?

Thanks, G.B.
 
G.B. go to the ty home page on the left side, scroll down to the bottom...in the online parts...look up your sled, you will see, radiator hose layout...if I look at it right it goes to the front cooler first from the water pump...anyways just take a look at it...
& if you are a betting man, I would say you might not have gotten all the rags/paper towels out... :bash: we all have done it & I will be the first to admit it...:oops: we all make them, so have a good look at it...cause it shouldn't take that long or be that difficult to bleed...

not sure, book is unclear(see if you can look at it,follow it),but the one coming outa the thermo stat goes to the bottom front of the recovery tank.

the bottom rear of the recovery goes to the r side H/E



coolant should circulate through the bottle till the t/s opens..then it flows through the bottle to the H/E

I have looked at the part exploded views and my shop manual and like you both said it is not very clear. The only thig that makes sense to me is the the water pump feeds up through the bottom of the t/s housing. The front side of the t/s housing goes to the head and the rear of the t/s housing feeds the right side heat exchanger. The only thing I am not sure on is were the left side heat exchanger feeds into.

Before I tear more of my sled apart, I am going to test the t/s since I have it out. I am also going to test my theory on the path of coolant flow and turn the motor over with the t/s cover off. If I am right, coolant should fly out at my face.

Thanks daman and theblues for your help! G.B.

I can't belive they don't have a flow direction in the books,my book for my '95 does. #$%&*

LOL..keep your mouth closed..
 
they do indeed have a flow direction in the manual, you need to have the correct manual for the correct sled. Look in the 2002 tech update manual page 2-55.
