Water pump or bad hose clamp
No. The top hose goes to the engine. The bottom hose feeds from the engine to the heater core back to the radiator.
look for antifreeze coming out of the radiator as the engine warms up after a cold start.
well you can either open the bleeder screw on the bottom of the radiator if it has one, or you can loosen the clamp on the bottom hose of the radiator and watch out for the big gush of antifreeze coming at you, take the radiator cap of before hand as a vent. good luck.
Once your vehicle is warmed up, if you have antifreeze coming out of the overflow you have too much in your radiator.
If it makes a boiling sound when it comes out then it is probably a bad radiator cap.
Internal engine antifreeze leak what else could cause besides headgasket? there is no antifreeze in the oil it is clean
Remove the bottom radiator hose. Put a garden hose into the top of the radiator. Allow the garden hose to run until the water coming out of the bottom of the radiator is clear.
radiator cap might be leaking
a hose or radiator may be broken. check your hoses and radiator. where is leak coming from?? front, right?? find general area and continue from there
your thermostat is inline with your radiator.. its in a junction coming off the bottom radiator three hoses plug into it.
Pressure test system to observe leak
you have a leak in a hose or your radiator itself. Look for antifreeze dripping from under car while engine is running and hot enough for the fan to kick on.
