2000 dodge dakota 4.7l is overheating. Replaced entire cooling system. No h20 in oil or vice versa. Any ideas?

I have repalced everything: radiator, hoses, thermosat, e-fan, radiator cap and water pump. There is no water in the oil or oil in the water. Also, there is no steam coming from the tail pipe. However, it is still overheating!2000 dodge dakota 4.7l is overheating. Replaced entire cooling system. No h20 in oil or vice versa. Any ideas?
Well you've not mentioned that you've bled the coolant system and more then likely after all that work you've air bubbles or air clogs in the system.Another thing is you should try testing the coolants quality and mixture with anti-freeze tester that places like walmart sell for about 7 bucks or so.Have the system pressured tested once you've tried all I've mentioned and the problem still exists.





Can't remember if that vehicle has a bleeder valve but there should be one either on the thermostat housing or in the system.Try starting the engine cold and make sure the coolant level is proper then allow it to warm up open the valve then wait watch for just coolant coming out then close it , do this on and off and watch the engine temperature gauges.





Once you know the coolant is good , mixed right , no bubbles etc , watch and listen for the fan to engage bec it should once engine idles warmed up a bit.If it doesn't run check it's fuse , relay , temperature sensor and the fan's wiring and the fan.





Make sure the thermostat although it's new be sure it actually is opening and working , you should of changed the coolant and at least run water through the cold engine and rad to flush it some before replacing the coolant.One thing I always try to do is test and change the coolant whenever dealing with water pumps or vehicles that haven't had it changed and are having over heating issues.











Hope that helps and best of luck.By the way if the rad was clogged etc it could be due to an air clog and if it was due to rust etc you'd clearly see the rust and coolant quality change , plus you can bleed the coolant system by leaving the over flow or rad cap off , stand back after it's started up watch for it to over flow and you'll see the air bubbles being forced out of it.Once you do this allow engine to cool right down , top the coolant off , start it up watch for further bubbles and top it off , but don't ever use cold coolant or distilled water on a hot engine.2000 dodge dakota 4.7l is overheating.

There is a test for a leaking head gasket that requires letting the coolant gas flow through a chemical. If it's leaking, the chemical will turn yellow from green due to exhaust gas coming into contact with the green chemical. Most big repair shops have this kit. Also you can put a well known brand of 'stop leak in the radiator and if the leak is small, it will seal it off. The most popular brand and one I like to use is Bars Leak. It not only stops small leaks quite well, but is recommended in coolant systems without leaks as it is a good rust prevent-er and water pump lubricant.
do you know that the fan is working? you may have a bad temp sensor or worse you may have blown head gaskets, I would suggest taking it in and having it diagnosed before you waste any more money on it. You could have already paid for a proper diagnosis and possibly the repairs for the money you have thrown into unneeded parts
You can borrow a coolant system pressure tester from autozone for a refundable deposit witch would have saved you a lot. trapped air in a fuild sysyem would create super heated hot spots under normal to adverse operating conditions, and a pressure tester would reveal that
well after replacing al that then good bet it is a head gasket and it dont have to stream or have oil mixing all the have motor or radiator pressure checked should do if you see drop in pressure its a bad gasket or crack head
