Hello and thanks for using Just Answer.I will try my best to help you with your question.
Double check your coolant level. Also you may want to have your engine block tested. This test checks for a blown head gasket. The test basically test the cooling system for engine combustion gases. Below is the test kit and how to perform the test with the engine running.
If the fluid turns from blue to green, you have a failed head gasket. You do not have to remove anything but the degas coolant reservoir cap to do this test.
the hoses are not even getting warm to touch even though the engine is hot. wil this still work or is it something else?
Are you stating none of the radiator hoses get hot including the upper and lower radiator hoses?
that is correct.
If none of the hoses are getting hot, it sounds like there is no coolant flow. You have already replaced the water pump, radiator and thermostat.
But you have to have some coolant flow because you state the heater blows hot air and then cold air and the engine overheats.
Are you sure the engine is overheating?
Does the coolant actually boil over out the reservoir or just the temperature guage shows hot?
This doesn't make any sense from my stand point. If your engine is heating up quickly, it is a good sign of a blown head gasket. The engine combustion gases are heating the coolant up in the engine causing the engine to over heat and boil out. Since the radiator hoses do not get hot, it a good sign.
The heater system will not cause the engine to overheat.
You replaced the thermostat, radiator and water pump to try and fix this problem?
ouch, for that price it would be cheaper to put down on a new truck. and move on. but if test was negative. that shouldn't be the problem, thank you and please get back with me.
Can you tell me how long the motor runs before it over heats?The big consensus is that you have a bad head gasket.
