Check the coolant level with the engine off.
When the engine is cold, the coolant level should reach the minimum mark, and when the engine is warm, slightly exceed it.
Attention: When the engine is hot, open the reservoir cap carefully. You can get scalded! When opening, put a rag on the lid. If possible, open the lid at temperatures below 90°C.
First loosen the cap a little to release the pressure. Then unscrew and remove the cover.
Add cold coolant only when the engine is cold to avoid engine damage.
For topping up - even in the warm season - use a mixture of antifreeze concentrate and soft water.
Attention: To continue the trip is allowed. especially in summer, top up with clean water. However, it should be replaced as soon as possible.
Carry out a visual inspection for leaks if the coolant level is well below the min mark.
External inspection of coolant leak
By squeezing and bending the hoses of the cooling system, determine their porous areas, replace the hardened hoses.
The hoses must be deeply planted on the connection fitting.
Check the fastening of the hose clamps.
Check whether the seal on the filler cap of the expansion tank is damaged.
Warm up the engine, check for coolant leaks in the area of the water pump.
If, when the engine is hot, coolant flows out of the hole at the bottom of the pump, the oil seal is usually faulty. In this case, the water pump must be replaced.
It is very difficult to locate leaks. Therefore, it is recommended to do this in a special workshop using the device. You can also check the safety valve on the lid here.
