I have a 2007 pontiac grand prix and it's beginning to leak antifreeze really bad. How can I check where the leak is coming from
if you have no tools...pressure tester,then move it to a clean spot and eyeball the location of the drip/s
On my 2006 Grand Prix, It was the heater hose bypass elbows that were leaking coolant. When you have the hood open and you're looking at the engine, these are on the left side of the engine (the side with the serpentine belt). If you see wetness anywhere in that region, they may need to be replaced.
I replaced mine with aluminum ones, DORMAN Part # 47065HP, instead of the original plastic ones, so they won't explode again.
let me/us know if it was the water pump...
Kelly I'm going to check it later today and I will let u kno
if its by the water pump also try and tighten the intake ...
