Why does the lower rad hose stay cold while the upper rad hose get hot Plymouth voyager 3 liter 6 cylinder also very little heat from heater new thermostat did not help?

Check the water pump and the radiator. If the impeller on the water pump has worn it may not be able to pump water. The problem could also be a partially blocked radiator.


1994 Plymouth Voyager 3liter very little heat upper rad hose gets hot lower hose stays cold new thermostat made no change any suggestions?

Check the water pump. ---- Also check the radiator it sounds like it's plugged and there is now flow of coolant.--- ( circulation ) Check for a heater flow valve in the heater hose they can rust shut easily it is a valve in the heater hose that opens when you turn on the heat and shuts when its not in use, if not then probably the core is plugged a radiator flush might help.

Why does the upper radiator hose stay hot while the lower hose along with radiator is cold with no heat in dash after replacement of bad water pump and thermostat?

YOU PROBABLY HAVE A BAD OR CLOGGED HEATER CORE IN THE VEHICLE. DEPOSITS AND SEDIMENTS CAN FIND THERE WAY INTO THE HEATER CORE (NORMALLY LOCATED INSIDE THE DASH ASSEMBLY). NORMALLY A FLUSH OF THE CORE WILL HELP YOU OUT, IF NOT, A NEW CORE WILL BE NEEDED. The core was really clogged, but under pressure it blew out, flushed the engine. Lower hose to the heater core coming from the engine is very hot, while lower radiator hose is almost even cold, what do you think?


How do you bleed air out of silverado coolant?

Try squeezing the upper radiator hose VERY HARD and VERY FAST with BOTH hands. Repeatedly. This will often force coolant into the engine and result in forcing air out.


Where is the radiator cap for a 2002 Ford Focus?

On top of the radiator. If there isn't an 'obvious' cap, then there really isn't a conventional type cap. Topping off the cooling system is done through the coolant resevoir. When I emptied the system on my daughter's 2002, I pulled the lower radiator hose and then refilled the radiator through a funnel into the very small upper radiator hose, and then topped off the resevoir. That seemed to have covered it as I have not had to add any more since then.

How do you change the thermostat in a 2004 E150 van?

It is very simple to change the thermostat in a 2004 E 150 Van. The thermostat can be found by following the upper radiator hose. After the thermostat is found, disconnect the radiator hose and drain it. Then, you will remove the two bolts that are holding the thermostat housing place. Remove the old thermostat and replace it with a new one.


Where is the sensor that turns the electric cooling fan on in a 2001 Jeep Cherokee Sport located?

The engine computer uses the engine coolant temperature sensor to decide when to run the electric radiator fan. It is located very near where the upper radiator hose attaches to the engine.
