Replacing the heater core isn't likely related to the water in your oil. Check the coolant overflow bottle for traces of oil too; if you see any signs there you probably have a blown headgasket. Also sniff the open bottle to see if there are any exhaust fumes noticeable. If your oil is already looking milky, the engine is in danger of failure since that emulsion does not lubricate as oil alone.
If a tech finds the headgasket has indeed failed, make sure that the cylinder head(s) are resurfaced to remove any warp that has developed. That isn't costly to have done and will insure that the new gasket doesn't fail too soon either.

Flush clogged heater core


Do you get steam out of the exhaust? Foamy Oil on your oil dip stick? Oil slicks in your water? Overheating? These are all things that could point to a bad gasket. If you smell anti freeze or are getting steam out of your defrost .. that would point to a bad heater core. I base my answer on the assumption when you say no heat you mean your heater is not putting out hot air???

Over heating


over heating can be caused by a number of things. your water pump could have died or the gaskets could have went on the water pump spilling your antifreeze every where. in which case you need to replace the water pump and gaskets. when you change the water pump you should replace the thermostat because they usually fail at the same time. your thermostat could have locked closed. in which case replace the thermostat. i recommend getting a fail safe thermostat so when it fails it gets locked open and then the car dose not overheat. your belt could have broke so your water pump wont turn. replace the belt. your radiator or hoses could be clogged with rust and sediments in which case you need to flush your radiator and change the anti freeze. you may be just low on anti freeze... so fill it up and see if it leaks anywhere. your tubes could have came off, be loose, or cracked and leaking; so replace or tighten them. your radiator could have a hole in it or leaking some where.. replace radiator. if you drive on dirt roads a lot the radiator could be full of sand and dirt could be full of mud if taken off road. just rinse the radiator out with soap and water. are your floor mats full of water or antifreeze? you could have a bad heater core. replace heater core. or you can cheat and take the two tubes off the heater core and splice them together. (which will leave you with no heat). your fan may have gone out so it wont cool the radiator. the last thing i can think of is very low or no oil in the motor. top off the oil.

1999 Taurus-NO HEAT-replaced thermostat,flushed heater core,still NO HEAT,ANY SUGGESTIONS?


Sounds like the problem has to be the valve is not opening and thus not allowing the hot coolant to enter the heater coil. Manualy open the valve (engine firewall) and see if heat is present. If this works check your cable from the dash switch as it isn't working the valve properly and needs replacing.

Not heating inside car


One or more of:

1. Your coolant level is low
2. Your thermostat doesn't close and needs to be replaced
3. The valve from the cooling system to the heater core is stuck
4. Your heater core is clogged

No heat in my dakota. flushed heater core and replaced therm with a reg one.


check for poor flow to heater core-change heater hoses -check for lime build up at intake connector or worn out water pump -if you only put water through core try using CLRlime cleaner in core-get two 6in pieces or heater hose hook them to core and pour it in and leave for 15 mins then wash out with water hose
