Remove both hoses and flush from bottom (warm) connection using medium hose pressure. Flush until clean water runs easily through. If this doesn't do it, time to replace heater core.

I've just gotten a 1987 Toyota Corolla and when I run it until it's warmed up, the lower return hose stays cold to the touch while the upper hose gets too hot to touch. Shouldn't both be hot?


indicates a blocked radiator
The fix is a new radiator
no-- it is not a problem thermostat as the top hose will not get hot if the water is not flowing through the thermostat
yes the bottom hose will get hot but will always be 10-15 degrees cooler than the top hose because the water is being cooled down by the heat exchange from the fins of the radiator
If you switch the engine off the the bottom hose will get hotter to equal the top hose as there is no water circulation from the pump

Why does my mazda drifter 2.5sleTDI the top radiator hose gets very hot and the bottom hose remains cold after a long trip.


The top radiator hose is were the hot coolant goes into the rad and the bottom provides cool to return.
If you hold your top hose while warmed up and running you can see if thermostat is open you can feel the coolant moving through. careful its hot mike

98 grand cherokee little heat.heater hoses hot top rad warm bottom is cold collant barely luke warm


While it doesn't seem likely, if you've changed, or had the thermostat changed.... I'd say you got a faulty thermostat. I am curious as to what your temperature gauge says the temperature of the engine and coolant is.. If your gauge is showing hot, I can think of two more possibilities... the water pump isn't pumping right... and, if the water pump isn't working right, the problem can be a cracked head or block, which can cause an airlock in the coolant system. Check the coolant or radiator cap.

I have a 2002 gallant and the heat doesnt blow warm air..any thoughts?


Make sure that the radiator is full and if you still dont have hot air then check to see if the top rad hose and the bottom rad hose are hot after driving for 30 minutes. Now if the bottom rad hose is not as hot as the top hose then replace the thermostat. If both the hoses are hot then check the two hoses going into heater core at the fire wall, both of the hoses should be hot, if not then problem is in the heater core.

My heater blowing cool air want blow warm or hot air


check top and bottom hose for heat if the top hose hot and bottom hose cold the thermostats not opening,or you may have a leak from a hose or water pump, maybe only a small leak but that would cause the system to lose pressure and lose heat from your heater at worst the head gasket may have blown

My BMW 318i has had a new expansion tank fitted after overheating and splitting.After bleeding the cooling system it seems as though the bottom hose is not getting hot any suggestions would be welcome


NORMALY THE HOT FLOW ENTERS THE TOP HOSE AND COOLER WATER LEAVE THE BOTTOM HOSE BACK TO THE BLOCK, SO IF THE TOP HOSE GETS WARM THEN THE RAD IS BLOCKED , IF NIETHER GETS WARM/HOT THEN THERMOSTAT NOT WORKING, OR YOU HAVE BLOCKAGE ELSE WHERE, SO REMOVE BOTH HOSES FLUSH RAD WITH HOSE PIPE, (WHEN ENGINE IS COLD) SEE IF WATER FLOWS OUT AT SAME SPEED AS U R FILLING IT, IF NOT ITS BLOCKED, 2ND REMOVE THERMOSTAT AND FLUSH ENGINE OUT, U CAN BUY RAD FLUSH/CLEANER AND TRY THAT,

Radiator problems


it may be a little off, but the lower water hose seldom gets very hot,, as its this hose that suplyes the engine with ""cold water"" the hot water comes out the top hose,, drains down the rad and cools on the way down then enters the engine through the bottom hose """if your engine stayes running in the normal place on the gage,,,and not over heating""" why are you spending money for nothing???""
you wont get the bottom hose to run hot unless the engine is cooking
