You could have a bad thermostat, a blown head gasket, a cracked head.
it goes up in tempature, the water bubbles and evaporates. it goes up in tempature, the water bubbles and evaporates.
because the bubbles are air the air can't fuse with hydrogen to become water because there is no excess hydrogen so it goes to the air as bubbles
1988 bronco gas gauge works when full than goes down faster than normal
It is a stone that goes at the end of the airline that the bubbles comes out of. It goes into the top hole of the box filter... When the bubbles comes out of that hole, it creates a current so the water will go through the filter.
The sending unit is probably bad, not unusual.
Did you check the -- sending unit !!
Ground the power wire and have someone watch the gauge. If it goes to full then the gauge is working. Clean the ground connection and turn the key on and if it reads then it is okay. If not then you have a bad sending unit.
If you're heating it strongly enough to boil, then because it's boiling. If not, the bubbles are probably dissolved air coming out of solution. The solubility of gases in liquids goes down as the liquids are heated.
because air is beneath the soil and it absorbed the water so the air goes up and the water goes down. No its because air is lighter than water so the air 'floats' on the water, bringing it to the top and creating bubbles
Most likely the problem is the sending unit. A good way to verify it is to run an actuator test on the scan tool for the fuel gauge. If the gage goes through its full range then the sending unit is most likely the culprit.
Where the top hose of the radiator goes is called the water outlet pipe. The sensor for the coolant temperature is in this pipe. There are 2 sensors. One goes to the gauge on the dash and the other goes to the computer. Not sure which is which, but if you unplug the one that goes to your dash the temperature gauge will peg.
first thing is to work out which part is at fault? I would start with dash gauge, find wire at fuel tank which goes to gauge, earth this wire out to body while having friend watch fuel gauge, if it goes straight to full it mean dash gauge is good but sender unit in fuel tank is probably at fault. Go to car wreckers for s/h part.
