been there.

Does anyone have air in their top hose or should it be full of fluid?
I honestly don't know.
The lady said it got up to 220 today. 95 degrees for a high in the city.
I gave the top hose a squeeze and there's clearly air in there.
Should I bleed all that out somehow or is it normal to have air in there?

edit... There was a little in there. I'm just being paranoid.

 

After reading and following this thread my 98 "MJ" had a great 30 mile test run with a/c on in 90 deg weather and 86% humidity. I think I can now drive it and not worry about the temps anymore. Highway speed 196 Deg Idle in traffic for almost 5 min, road blocked scraping up a head on, 206 deg back to the shop and was not even hot enough to trip the cooling fans, yes they do work.
Thanks for the information.

 

Be paranoid it is good I was not and it cost me the engine in the P38. That is why I am all over MJ.
I would do a pressure test to MAKE sure that a sleeve has not slipped. As far as a top hose you will have AIR when the thermostat closes and stops water flow.

 

Hey spike when just replacing t-stat going by your method about how much coolant can I expect to lose? I have a whole new bottle just didnt know if this was enough or if I should go ahead and pick up another bottle

 

The system holds 3 gallons, you should be good. I mix about 60% distilled h20 to 40% coolant. Unless the bottle you have is pre mix. Even then, I can't imagine losing more than a gallon when changing a t stat.

 

If you do it with a cold engine you wont loose much, at most half a gallon, at most.

 

I've since installed drains in my radiators, but before that, or on one that doesn't have a drain I made a drain method with some vinyl tubing, a 'T' connector, and a cork.
What I ended up with was a long piece of tubing to insert in the radiator, it runs down to the 'T', then continues with a short piece in to the jug. On the branch of the 'T' I have another longish piece I use to manually start the siphon the old school way, just blocking off the end in the jug while I do it. Once it's starts flowing I stick the cork in the "mouth piece".
Works the same for siphoning fuel in to the tank from jerry cans on the roof rack. Cost me about $2.

 

Todd, I believe that first photo needs to marked "explicit".

That has to be the first snapshot of a Rover given a Hummer.
