is it damp under or near the dash ? if so its most likely your heater core cause it will cause a very bad smell that would be first thing I would check
Probably not. If the water pump is gone it would be a separate issue
Basically because the pump has gone bad.
Your car will not neccessarily smell like Antifreeze if your water pump is going, in my personal experience it sounds like your HEATER CORE is shot. That is what usually makes that smell, unless you spilled some on the engine. Also, if the water pump was going the car would run hot and/or overheat.
water pump or seal gone bad
Bad water pump, the seal is gone. Get a new water pump.
I had one do this and I had to change the brake calipers. Problem was gone.
Yes.
Sorry to say but it's the pump gone bad.
If your pump is not cycling often the water in the pit will be stagnant and can get a little smelly or if the water coming in from the ground has a natural odor to it (like sulphur)
if you had dirty mexicans working on your vehical
Coolant weeping and noise.
Most water pumps have a (weep) hole just under where the pulley go's into the pump body.=ok you fan blade is bolted to the front of your pump. looking down if you see a trinkel of water or a water stain on the front of it under the shaft you can bet your pump is gone.=
