water pump

Post by nissannewby »

Hey mate check the water pump its sometimes hard to pick up a leak on them as the engine temp evaporates the water running out of the tell tale on the water also with the cracked while the engine is running open the radiator cap if its blowing bubbles in the coolant then this is the case.

is the turbo water cooled could this be using water and evapourating it with the heat it produces?
