Your first place to start is your coolant hoses. If they're intact I would then look to your water pump, if it is intact and working properly, then you most likely have a blown head gasket. Repairing that yourself can be intimidating, but so long as you have the proper tools (I.e. torque wrench) and have some mechanical ability, it's not that hard to do yourself. Just make sure you clean all the old gasket off completely and install the new one as designed, you should be fine. Hope this helps.

Hi! Here are some steps you can take to address the issue:
Identify the source of the leak: Before you can fix the leak, you need to determine where it is coming from. Check for any visible signs of antifreeze on the ground, and look for any puddles or drips under the engine.
Inspect hoses and connections: Check the hoses that carry antifreeze to and from the engine. Make sure all clamps are tight and there are no cracks or leaks in the hoses. Also, inspect all connections, such as those for the radiator and the thermostat, to see if there are any leaks.
Check the water pump: The water pump is responsible for circulating antifreeze through the engine. If the water pump is failing, it can cause a leak.
Check the radiator: If the radiator is damaged or has a hole, it can cause antifreeze to leak.
Check the head gasket: The head gasket can leak if it is damaged, causing antifreeze to escape from the engine and pool on the ground.
Replace any damaged parts: If you find any damaged parts such as a leaking hose or a damaged radiator, replace them. You can check our selection at CarParts.com for the right parts for your Buick.
If you are not confident in your ability to diagnose and repair the issue, it is recommended that you have a professional mechanic inspect the vehicle to determine the source of the leak and make the necessary repairs.

If your 2010 Buick LaCrosse is leaking antifreeze from under the left side of the engine, there are a few potential causes of the problem. Here are some things to check:
Radiator hose: The most common cause of an antifreeze leak is a damaged or worn radiator hose. Check the hose connections to ensure they're tight and look for any visible signs of damage, such as cracks or splits.
Water pump: The water pump is responsible for circulating the coolant through the engine. If the water pump is damaged or worn, it can cause a leak. Check for signs of coolant around the water pump or a loose or damaged water pump belt.
Heater core: The heater core is a small radiator located in the passenger compartment of the vehicle. If the heater core is damaged, it can cause an antifreeze leak inside the vehicle. Check the passenger side floor for any signs of wetness or a sweet smell, which may indicate a leaking heater core.
Freeze plugs: Freeze plugs are metal discs installed in the engine block to protect the engine from damage due to freezing. If a freeze plug is damaged or corroded, it can cause an antifreeze leak. Check for signs of coolant around the freeze plugs on the left side of the engine.
It's important to fix an antifreeze leak as soon as possible to prevent damage to the engine and overheating. If you're not comfortable troubleshooting the issue yourself, it's recommended to take your vehicle to a qualified mechanic for diagnosis and repair.

Ask the last driver if the car overheated, You should check your hoses every so often for wear. check for cracks, check fittings and squeeze the top one while the engine is cold. If it collapses then both need replaced. If the vehicle overheated, I would check why it overheated, leaking radiator, bad hoses, bad thermostat, water not flowing in the radiator, thus bad thermostat or water pump, LOW or TOO MUCH ENGINE OIL. Inform every driver not to continue driving when the thermostat gauge is red or engine light is red or worse, red and blinking. You must find a safe place to pull over and turn the engine off as soon as safely possible away from traffic or any other possible dangers. If the vehicle overheated, it may have blown the head gasket or worse, warped the head. If you have the equipment, do a pressure test, replace the head gasket, and pressure test again. Unfortunately if it still leaks under pressure test, it is more toward a warped head and may need machined or a new one. Ask a professional at a shop where you can trust, they can diagnose, send it to a machine shop at a good price with a warranty if qualifying. or check junk yard and take your chances or see if buying a new on is more cost effective. however check with a professional first.
