i got leaking coolant under my boxer...

I can't see any leaking point through my bonnet....

Can it be my water pump????........

If I add coolant to the max line on head tank...

It will leak more coolant out......

Best to borrow a cooling system pressure tester & see where it's going. Coolant will be leaking from around timing covers if it's the water pump. A possibility if you can't see it leaking from the engine is the heater core inside the car. Is the carpet getting wet? Or pull your spark plugs out & see if it leaks out from there with the system pressurised.

THX for help......when I go out to local shop today...I open the bonnet...

& look for any coolant leaking....but there is no coolant.....& I start the engine...

about 5-10min.... still can't find any thing......will the heater core leak make coolant

drop in front engine(after) the bonnet... there is where I found coolant....???

or....where I can find the coolant..if my heater leaking????under steering wheel?

pressure test I have done about 3 month ago...the result is good....I think maybe

I can do it another day.....or..I can bypass it?

So it's leaking coolant *onto the ground* from under the engine somewhere, you just can't see where? In that case, it could be the water pump.

If it was the heater core, you'd have wet carpet, but it wouldn't usually leave coolant under the car.

Absolutely! It's quite possible that coolant is spraying out under pressure. Start with the obvious issue first, much easier ;)
