96 bonneville heat
I have a 96 bonne with about 215,000 miles on it. Runs pretty good, tuned it up, changed all the vital sensors.
My question is. I changed the thermostat and toppped off the coolant level, both in the coolant tank, and in the radiator. When the heat gauge in on the dash gets to like almost 200, I turn on the hater and have some heat.
I know that when you open the system, you need to "burp" it to get the air out of it.
Well 2 things come to my attention when I go to do this. One is the upper radiator hose isnt hot, and 2 when I open the screw that is on top of the thermostat housing, shouldnt you get some air and then all coolant to come out when you open the screw?
I dont get any at all, weather I crack it when the car is running or when it is shut off.
I guess one other thing, and this may be the main culprit of all of this is, the radiator cap is still cool, and I can take it off and not have any pressure on it at all.
Does the radiator cap make the pressure? If so, then I will start with the cap....
So to review>>>>>
The top hose doesnt get hot when at full temp,
No spray out of the thermostat housing when screw is cracked open
Cap is cool and can be opened up and has no pressure behind it.
Thanks for your expertise in this.
