Question about 1998 Dodge Caravan
3.3 liter motor with air, had fluid level ckeck a month ago it was o.k. But now you can not even see the level with cap off. temp gage shows half way not over heating. what gives???
You should check the coolant level every week when you have a leak. The level in the radiator is probably low, and it could also have air in the system now. Try filling it up and then check it again tomorrow until you know it is full.

Replace the bad radiator hose first. Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator. Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it. Fourth- Check for leaks by looking for the colored dye. If it's not the radiator hose, then could possibly be a pin hole in your radiator. Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

Testimonial: "Helpful & quick feedback! Thanks! "
First thing first, turn off the engine wait for 15 - 20 mints, open the radiator cap and fill it up to the top then start the engine and see if it needs more water adn add as needed, then wait till you ca see the water circulating in the radiator now instead of corculating if it starts boiling out shut the engine replace the thermostat and do the whole thing again.
unless there is water in the engine the gauge will not be able to show the actual temp of the engine, so always malke sure you have water / antifreeze

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

Try stopping on a steep incline--does the heater stay warm? If yes, what you have is an air bubble that hangs at the heater hose until pressure from the water pump blows thru it as the engine speeds up. Park on an incline, open the radiator cap, run the engine until the thermostat is open, turn the heater on, crack open any/all bleed ports to release any trapped air, and fill the radiator to the neck. Wait until the level stops dropping and make sure bubbles don't continue to come up. If they do, you may have a blown head gasket that will keep forming these bubbles until you change the gasket.
