Please Help!

I have a 2000 tiburon 2.0..

About a month ago the upper hose began to leak, the fan blower fuse went out, and the car started to over heat. I replaced the thermostat.. the housing until.. fan blower fuse.. and the upper hose.

About a week later the car begun to over heat again.. This time it was leaking a ton of fluid from the radiator, the ac fan went out, and the upper and lower hoses begun to leak. So I replaced the the radiator.. the fan.. tightened the upper hose and replaced the lower hose.

Now when I drive the car still over heats but it takes me driving about 40 or so miles first. When it over heats the hot air from the heater turns cold and then the car gets hot. I have checked the oil thinking that I blew my head gasket or cracked my block but the oil looks perfect. Also their is no smoke coming out of my exhaust.

Also I see no leaks in the heater core or the water pump..

My only idea is that either the water pump, heater core, or thermostat is bad. I have heard that often times the thermostat has to be changed often to find one that actually works.

Please if you have any suggestions let me know..

Thank you

Ok so a quick update...

Checked thermostat and it works perfectly fine.. Then we decided to take out the water pump.. which also looks fine.. It appears my only other options are a blown head gasket and a cracked block. When I use the block tester to determin whether or not that is the main cause. How can i tell whether its a blown head gasket verses a cracked block? Im under the impression that both a block tester and a compression test on the spark plugs can only identify that you have a leak some where but not were...

Dear Monique,

A cracked block would not normally occur with overheating...but a warped head can and does occur with severe overheating and this leads to a blown head gasket. Since you have checked the oil and found no traces of water bubbles or milky white on the dipstick, this may only prove that you do not have coolant flowing across into the oil gallaries. With the engine cold, remove the radiator cap and start the engine. If you see bubbling and smell exhaust gas, you have a head gasket leak directly out of the cylinder into the water jacket. Also common. This will cause an overheating situation as the gas bubbles in your coolant can block or slow the coolant flow at the important contact layer that touches the outside of the cylinder walls. Just remove the radiator cap, and sniff the bubbles to confirm.

Fix: have your cylinder head rebuilt which includes machining the face back to square.

If the fuse is blowing for the fan then the motor is bad and is drawing too much power therefore blowing the fuse, replace the fan motor but keep the receipt. I had this same problem a few yrs ago, I went through 2 motors from autozone in a 3 month period before getting 1 from checker and didn't have the problem anymore.
