Or blown head gasket, bad radiator or fan clutch.. You'll have to check/replace parts to find out.

 

As my 318 warms up the antifreeze slowly starts dumping out of the overflow. Check it a few hours later and its always low. Whats happening junk thermostat? Or waterpump?

 

I see zman does that trick too.....

Take off the radiator cap, top off the radiator, start the engine. (no cap) If you immediately get coolant blowing out the radiator, you have a blown head gasket, or cracked head. Time to tear down the top end of the motor.

Check your oil as well. If it looks like a chocolate milkshake, STOP driving it until it is fixed.

 

LOL, At first I was getting annoyed, but now I'm thinking it's kind of fun.

 

no it takes a couple minutes for it to leak out. i dont think its a headgasket or head. any other ideas

 

and nothing in the oil

 

Do you see bubbles in the radiator when the engine is running? (cap off.... don't open hot, you WILL get a RUDE surprise.)

 

What is your temp gauge telling you? is the engine overheating?

 

no water in the oil, no bubbles, it takes a few minutes for it to leak out... i have no idea

 

guage doesnt work but i can feel it get warm but i wouldnt say hot
