Question about 2004 Chevrolet Monte Carlo
I have a 04 monte carlo with a 3400 v6 engine, 69 thousand miles. when the engine is cold the motor has a rattle for 1 min then goes away. car drives great no other problems, all techs tell me this is common for the gm 3400
If it is like a ticking sound then it is the fuel injectors, but if it is like a slight knock than goes away it is more than likely a cold start(which means the oil has all drained into the pan) which would cause a slight sound and then go away after a bit.

Check for bubbles coming up in the radiator--signs of blown head gasket. If no bubbles, try replacing thermostat.
Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.
