It could very easily be the intake gasket. This is a common problem on almost all GM products made between the mid 1990's and 2004. The issue is that the gasket is made of cheap plastic and the constant warming and cooling of the engine causes it to crack. It can cost anywhere from $600.00 to $1200.00 to replace.
Low coolant, failed waterpump, stuck thermostat, missing belt, inoperative fan, plugged radiator.
There are many possible causes of overheating. They include low coolant, inoperative radiator fan, failed water pump, missing belts, restricted radiator, failed head gasket.
Overheating can be caused by the thermostat, plugged radiator or a faulty headgasket. On the Saturn S-Series, overheating is more commonly caused by a missing air dam (if you mostly drive in town), or a failed cooling fan.
Could be,low on coolant, stuck or sticky thermostat, faulty fan clutch, restricted coolant flow inside radiator, restricted air flow outside radiator, broken or missing fan shroud,
Could be, a stuck closed thermostat, low on coolant, bad head gasket, cracked head, restricted coolant flow inside radiator, restricted air flow outside radiator, missing or broken fan shroud, fan clutch inoperable,
Possible causes: Insufficient/no coolant in the system; insufficient antifreeze in the coolant and the coolant is frozen: the water pump is faulty and is not circulating the coolant; the belt that drives the water pump is loose or missing.
My Chevy Syburban is consistently loosing antifreeze every couple of days. Put new water pump on, radiator hose still loosing antifreeze somewhere What coud be the problem I do not want to replace the head gasket or something else will cost over $1000 If a head gasket is blown, the vehicle will normally run rough, if at all, due to water vapor in the cylinder(s). If your windows are constantly fogged up, you probably have a faulty heater core which would deplete antifreeze. There might also be a leak in the radiator or transmission cooler. Or maybe just a faulty hose.
There are several possibilities that come to mind. Coolant loss (IE) leak in cooling system Thermostat stuck shut Water pump failure Thermostatic fan clutch failure Radiator Cap failure Collapsed radiator hose Cooling passages obstructed Dirt and debris obstructing radiator Fan shroud, air dam, valances broken or missing
Low coolant, radiator restriction (inside and/or outside the radiator), inoperative radiator fan, missing/broken fan shroud,
My first thought is have you checked your fan? Some fans spin but not fast enough. Electric fans get weak and direct drive fans have a clutch that gets weak. Another issue is the air dam ( the piece of plastic under you car). Most cars are designed to push air through the radiator if the air dam is missing it might be a problem.
Overheating. Loosing coolant with no apparent leak. White smoke with a sweet smell from the exhaust. Coolant in the oil. A foamy substance on the underside of the oil cap. Air bubbles escaping from the radiator. Engine missing on one or more cylinders. Loss of power.
Could be a number of reasons from minor to major problems. Could be as simple as a faulty thermostat, faulty fan clutch (if applicable), missing or damaged fan shroud or more serious problems like a cracked head or bad head gasket.
