My fan comes on now, and the car no longer has any hesitation, but I still have another problem which is causing my car to overheat. Whenever I've filled up the radiator with coolant, when I got back home from driving it(yes I did wait for it to cool), the coolant in the radiator had gone down A LOT(if not all of it). I had no idea where it was going. Come to find out the coolant in the reservoir had gone up and is now overflowing. What's happening is the coolant is going into the reservoir through the overflow hose, but for some reason it can't go back into the radiator. I have no idea what's causing this to happen

Could be a couple of things; thermostat among them; but I had a weird problem like that and it was a leak in the overflow tank that was causing strange problems; easy to check.,

Check for leaks by doing an idle in the driveway for 15 minutes- long enough for the resevoir to open and the coolant to start flowing.
You do this by taking the radiator cap off BEFORE you start the car- not the overflow. Watch for the fluid to drop and then start churning.
If it doesnt churn, your thermostat is stuck and you need to replace that. If it does, check for leaks.
I will guess it is that or your water pump needs to be replaced.
The wrost thing would be that your coolant is finding its way into your engine and leaking through into the oil. That would be a cracked head or a failed head gasket.

sounds possible that its a head gasket leak. The gasket leaks from the exhaust ports into the coolant passages and pushes exhaust pressure into your cooling system causing the coolant to be pushed out. Only place for it to go is out the overflow. Sounds like a mechanic needs to do a pressure test on your cooling system and find out where the leak is tho.... most likely head gasket. Most common explanation

You have an air pocket.....this means there is air in the system and you HAVE to get it out. Trust me on this one, if you have no idea how to bleed a cooling system take it somewhere before you crack a head or a block..........when it comes back up that means its starting to overheat because the air is trapped up by the thermostat and it wont open...........oh and the way you put the URL in it wont work............the simi colon and periods screw it up

either a very bad radiator cap or a blown head gasket. have a shop test for both.
