Car Forum / Dodge / Dodge Trucks / May 200501 Dakota 4.7 with antifreeze smell
I'm not sure but, I think my 01 Dakota with 4.7 has a head gasket leaking. I have looked under the hood and can't find any leaks and it seems like the smell is worse when I first start it in the morning. Is the 4.7 known for having problems like this? Thanks Ben check for coolant from the a/c drain-could be heater core rt Where is the a/c drain? I don't smell the anti-freeze in the cab though. I had a couple guys riding on my tailgate for a short while yesterday and they smelled it and then I thought I smelled it coming from under the hood after that while standing outside the drivers door. But, couldn't find any visual evidence of a leak under the hood. Heck, I can't even tell where the thermostat goes on that engine. > Where is the a/c drain?

Take a good look around the water pump. The seal went on mine at about 45k miles. There wasn't much more than a couple of drops at any one time. Had the dealership replace it; the "new" one failed at abour 200 miles. The "plastic" impeller split into two pieces. Wayne The thermostat is on the bottom right side, just follow the lower radiator hose. Remove the plastic splash shield under the front end, and go in from the bottom. > Where is the a/c drain?

Thanks > > Ben Heater core if you can smell it inside at all. Way up under the dash, The floorboard or jute backing under the carpet will be damp generally the carpet can be dry unless it is really a bad leak. the bad news... the heater core means the whole dash and steering column must be removed. disabling the airbags is imprtant too! Seats, removal optional. The heater core inlet / outlet tubes are in front of the drivers side of the firewall. They feed along the inside of the firewall to the passenger side and are inside the a/c evaporator box. The A/C will need to be evac'd and recharged too. Dealers charge around 1000.00 to do the job! Good luck > That sounds much more like a heater core leak. > [quoted text clipped - 4 lines] >> >> Ben |
