YOUR WATER PUMP IMPELLER IS PROBLEY DAMAGED .IT IS A COMMON THING IT IS A PLASTIC IMPELLER AND THEY COME LOOSE FROM THE SHAFT ALL THE TIME AND THAT MEANS THEIR IS NO WATER FLOW THRU THE HEATER CORE AND AS YOUR FANS GO IF THERE IS NO FLOW THRU COMPLETE SYSTEM (SUCH AS THERMOSTAT) THE ENGINE GETS HOT BUT THE RADIATOR DONT .THERES A SENSOR IN RADIATOR THAT TURNS ON THE FANS AT HIGH SPEED WHEN IN OVER HEAT MODE I KNOW IM A VW TECH
Is your fan turning and blowing air across the radiator? Take radiotor cap off before you start the engine and then wath inside the radiator and check to see water circulating thru radiator. Is your car smoking?
Go to an auto parts store to get the code(s) read for free from the OBD. That will likely explain the Check Engine light (emissions related).
Also sounds like the screws weren't torqued enough (or Loc-tite not applied) by your repair mechanic.
Recall that radiator water (and anti-freeze) is what circulates in the heater core. Hopefully it is just a leaky core and turning off the heat (or shutting of that water circuit) will eliminate the smell.
Are you losing radiator water? That would be a tip-off.
Have you checked for water in the engine oil? Bad news if that's the problem.
I presume you have a pressure gauge installed on the radiator. and the engine is running. If you have no pressure after running the engine until the water temperature is hot, you should check the instrument of your vehicle to see if the engine is not over heating. The water pump is circulating the water so the water is in constant motion and is cooled by the air flowing thru the radiator. The air is drawn thru the radiator by the fan, either engine driven or electric powered. When the cap is off you should see movement of the collant in the radiator. also chech if you see any oil residue mixed with the water. in that case the water level should drop because the water is draining into the oil tank.. If you see no water movement the water pump is not moving the coolant thru the engine and the engine will over heat.The water pump is bad in that case.
Overheating is not always caused by a bad water pump or bad engine firing timing.
The most common causes are:
faulty radiator cap: steam/water will be escaping from the caps when engine is hot or oveflow tank overflows or empty!
crack cylinder head gasket: check when engine is cold thru radiator cap hole for milky oil in water radiator or large bubbles in radiator water after starting engine. Also check if water steam comes out of exhaust.
cylinder head itself: same symtoms as for gasket above.
Do you have anti freeze in it? did you replce the radiator cap? is the fan clutch good? is the AC condensor full of bugs and the radiator? are you low on transmisson fluid? or Motor oil? all these will cause it to get hot.
Its the upper radiator hose should be located topside beside the engine oil dipstick,any smaller hoses you have running into the radiator are heater hoses, the lower radiator hose is where coolant enters from radiator into engine and is pumped up with water pump thru water jackets in engine and eventually returns thru the upper radiator hose which is most prone to damage due to splitting and cracking, I hope this helped.
you could have a broken cylinder head gasket...you are loosing water thru the engine pistons that is why you have smoke on tail pipe when engine is running.
our simple test if you have a blown gasket is to fill the radiator up to the rim and then be carefull, do not stay in front of the radiator then ask someone to start your engine and watch the water in the radiator, if the water rushes outside the mouth of the radiator, then you have a blown gasket.
if not, then put the gasket cover and run the engine for 20 mins and watch the temp gauge, it should not over heat.
