There is a drain plug underneath the radiator It will be on the bottom right if you are facing your vehicle. Then fill from your Radiator.
first you will want to locate the petcock (radiator drain) it should be near the bottom of the radiator on the side opposite the lower hose. simply turn the petcock (do not fully remove) the petcock is designed to let the fluid out without having to be completely removed. in order to expedite draining of fluid remove the radiator cap and there should also be small brass "vent" screw, its located near where the upper radiator hose connects to the engine and also within 2 inches of the thermostat. something else that i do to get some of the fluid from the heater core out is to squeeze the lower radiator hose near the engine block (reachable from the serpentine belt area of the engine.
~squeezing the hose produces a small pressure wave that forces fluid out and lets a little air in. making the draining process go a little faster.
the inlet hose should be the lower hose...
the radiator should have 4 other smaller hoses these are for engine oil and Transmission Fluid.
i always take mine to the dealer and let him/her to take care of it i trust the dealer to do a good job on my van
its underneathe the alternater, right next to the bypass hose inlet.
Drain the radiator and dispose of the coolant as its toxic to animals. Remove the top radiator hose, and water inlet. Remove the thermostat from under the inlet and replace it. Reinstall the inlet and top hose then fill the system with new coolant.
its located on the heater core
The thermostat is located by the side of the cylinder block near the coolant inlet. Remove the coolant inlet housing after disconnecting cables and loosening the holding bolts. You will be able to remove the thermostat to replace it.,
2 - inlet & outlet
Thermostat is located on side of cylinder block, behind coolant inlet housing for lower radiator hose and the generator. drain cooling system. rotate accessory drive belt tensioner clockwise to release tension from accessory drive belt. remove accessory drive belt. remove mounting bolts and generator. disconnect electrical connector from engine coolant temperature switch for removal of coolant inlet housing. remove nuts, coolant inlet housing, thermostat and gasket.
Start the truck. Turn on the heater. Hold both hoses in your hands. The first one to feel warm is the inlet.
inlet air temp should be between the throtle and air filter box on the air intake hose coolant temp should be close to were the upper radiator hose connects to engine there maybe 2 coolant sensors one for computer one for radiator cooling .
In the PWR the top houses the steam outlet, not inlet, and coolant flow is applied to the pressure vessel inlet connections. A glass lined vessel would simply not be durable enough for a 40 or hopefully 60 year life. If it started cracking or peeling off, how would it be repaired?
No it will not, it will just back flush the heater core and clean it out.
u need to take both the radiator hoses off the radiator and take a water hose to the top inlet. leave the cap on it. and let water run through it to flush it out.
