Zerex G-48 Formula Full Strength Coolant The ZEREX G-48 coolant is ideal for BMW cars. “Waiting for at least 15 minutes allows the hood, engine and leaking coolant to cool.” What is the best coolant to put in BMW? “Your personal safety is most important,” he says.

If you’re noticing higher-than-average readings on your vehicle’s thermometer, you could be experiencing coolant loss through a leaky gasket or damaged hose. You typically need to flush and fill your coolant every two years or 30,000 miles. To top up your engine’s coolant, you can simply open the reservoir cap (be careful the engine is not too hot and use a cloth wrapped around the cap to open it, as there could be some residual pressure left in the system) and add to the fluid level – what you use to do this is very important though. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem. With gloves on, grab it and wiggle it back and forth. With the engine off, open your hood and locate the water pump pulley. How do I know if my water pump is working? Holes or leakage system on the dry side of the water pump.The water pump has several gaskets that can be damaged or worn out over time. What are the signs of a water pump going out? The longer you wait the higher the coolant leak repair cost will be. Why is my car losing water but not overheating?Ĭhances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. There are many different types of coolant, so it’s important to know what variety is right for your car or truck. Is antifreeze the same as coolant?Įngine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. If you were to just use water rather than the coolant mixture, high temperatures inside the motor would easily boil that water and cause it to evaporate, meaning you’d quickly have no coolant at all and the engine would easily overheat. While driving, keep an eye on the temperature gauge.

“A professional will need to inspect your car’s cooling system,” says Reina.

The easiest way how to fix low coolant is to begin filling your coolant back to acceptable levels and allow the coolant to soak back into the system. When the coolant rises to the cold fill line, replace the cap and tighten it until you feel it click. You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water. If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). Does BMW take a special antifreeze?īMWs have specific coolant requirements (nitrite and phosphate free) to prevent build-up and corrosion of aluminum components, so not just any off-the-shelf antifreeze will do. Continued use of an overheated engine could lead to permanent damage, such as pistons welding to the cylinders. So, without enough coolant, the engine could overheat or seize up. Is it OK to drive with low coolant?Ĭoolant helps pull heat away from the engine. It could be a blown head gasket, a fractured cylinder head, damaged cylinder bores, or a manifold leak. When you are losing coolant but no leak is visible, several parts could be the guilty party.
