2001 pontiac sunfire will not hold any antifreeze, why and whats wrong with my car????


General advice:U must track the leak .How much it takes to loose the coolant?.If the coolant shows under the car must identify the tubes clamps that need tighten or replace.If a radiator related problem need clean/solder/replace.If leaky water pump,replace.If no trace of coolant ceck the oil.If is color altered(milky)u have a head gasket ahead (with head revision)or a broken engine block/piston cyclinder.If the oil is ok,ceck the smoke:whity smoke means coolant in the pistons head.Again best guess:head gasket (can leak also in the intake manifold).Very rare coolant shows in some cars in the power stearing oil (!?) track the tubes.Tip:colored coolant (green...)is better visible in leaks.Tip:water coolant may show rusty spots where dissapearing (radiator,expansion deposit,pitched tube).Hope u deal it.Cheers.

My 2001 sunfire starts fine.but after i drive for about half hour it will stall and wnt start again for half hour.the oil light stays on when this happens.wassup with this?


This happened with my Sunfire. It was the radiator. The engine wasn't cooling, but the sensor wasn't showing that it was overheating. So the engine would start when it was cool, but as soon as it got hot, then if I stopped it wouldn't start again.

Need to flush coolant and replace with new coolant can not find drain point for coolant.


Not all cars have them. Sometimes it's just a plastic screw-in plug. If there is no petcock or plug at the bottom of the radiator (right or left corner), you have to just unclamp the lower radiator hoes and pull it off. Be careful if the coolant is hot. OK?

2001 Pontiac Sunfire is dumping antifreeze out the overflow. Could it be something other than thermostat?


Common causes include: leak from engine, hoses, etc. causing overheat due to low coolant, electric fan not coming on, internally obstructed radiator, external obstruction to radiator (leaves paper. plastic bag on front of radiator of stuck between radiator and A/C condenser), bad thermostat and last, blown head gasket. Proper testing for any and all these conditions will give you the answer you are looking for. If the antifreeze is overflowing without any overheat, it can either be over-full, or in some cases, a head gasket can do this by filling the cooling system with exhaust and driving the coolant out.
