So one day I left my friends house then he called and said your lost alot of coolant in my driveway so i lost about a liter of coolant there... then my car lost a liter of coolant a month (during winter)

My car was revving up and down like i need my radiator burped if you will lol
But it turned out my throttle body just had a bad spring and i fixed that

Now i dont really lose any coolant but not sure if the water pump is broken any way to tell??? or anything else that could explain this

 

Start it up and chack for leaks.
