yup you read it right, I get home turn off the engine and a few seconds later voila I have my own driveway waterfall. I am really disappointed, just got my Montero back on the road then this happens. I have already ruled out the radiator, hoses, and T-stat as possible sources. It normally dumps about a cups worth of fluid every time and doesn't seem to leak at all while the engine is running. I'm stumped anyone got any ideas?  Edit: Guess it's worth noting that the leak dumps all over the front of the engine block and doesn't appear to be leaking from the top or rear of the engine. |

Pressure test? Unless the cooling system was not purged if drained/refilled and it blew out the overflow.

I had that happen too and my exhaust would smoke like crazy cause of coolant getting to the exhaust. Found out there was a rubber coolant line hose that leaked and had a crack in it at the rear of the motor

I had the system drained so I could replace the water pump if that's what you mean.  I had that happen too and my exhaust would smoke like crazy cause of coolant getting to the exhaust. Found out there was a rubber coolant line hose that leaked and had a crack in it at the rear of the motor No coolant is getting on the exhaust manifolds, and I'm not smelling any burning off the engine so I know it's not leaking from the back anywhere. |

Did the guys removed the radiator to do your helicoil?

Oh yeah there is no overflow entering the reservoir I've kept a good eye on it. And no I didn't use a coolant vacuum and refill kit, until now I didn't know they existed. I filled the radiator then turned the engine on without the radiator cap on and slowly kept filling it while the engine was running, wound up with 1 gallon antifreeze and 1 gallon distilled water before it wouldn't take anymore. It's probably worth noting on the idea of air trapped in the system that I can't run the heater because the knob won't turn to the right, it springs backwards when I let go so that may be causing an issue? Did the guys removed the radiator to do your helicoil? I had it removed before it was towed over there. |

So I just found an angle where I could shine a flashlight down into the V of the engine and it's full of antifreeze. Sounds like it could be the Oring on the back of the pump assembly on the end of that pipe that goes through the V to the water pump.

Requires pulling the intake plenum I believe. |

Requires pulling the intake plenum I believe. The O-ring will be on the end of the pipe that plugs into the pump assembly so I shouldn't have to do that. I could have sworn I replaced it but for all I know the assembly may not be sitting on it right. |

Sounds very similar. msport97.proboards.com/thread/10965/water-leak-pump-help-fixed?page=2Edit: did you do the water pump, gasket when you did the timing belt. |

Yup, I pained myself to make sure it was seated right when I did it. It took me like 30 minutes to get it perfect without some kind of silicone sealant to hold it in place. I'll tear everything down in the next coming week(s) to figure it out but I need to acquire some money just in case I need to replace something. In the mean time I got a large plastic bin to put down under the front end to catch the waterfall and some 50/50 antifreeze to keep in the back at all times just in case. |

...Oh yeah there is no overflow entering the reservoir I've kept a good eye on it. .... Check the over flow hose and make sure its not plugged up. After enough years, if the coolant system is working properly, the coolant in the hose will evaporate leaving a deposit of crud. Eventually the hose will plug up and the overflow tank won't do what its supposed to do. Make sure there's nothing coming out of the bottom of the water pump. A lot of times the pump will start leaking and its a hard one to diagnose 'cause the fan blows the antifreeze back away from where it's actually coming from. Edward |

I was losing a lot of coolant when I first bought my Sport. The overflow reservoir would fill up and start dumping coolant on warm drives. My issue turned out to be a radiator cap that disintegrated and was letting coolant just flow unimpeded right out of the radiator.

My issue turned out to be a radiator cap that disintegrated and was letting coolant just flow unimpeded right out of the radiator. +1 The antifreeze was running back along the fender and draining out behind the front wheel below the BMC. Drove me nuts looking for antifreeze from the wrong end of the engine.  Oh, and check the upper hoses and make sure they're not leaking around the ends. Edward |
