Are You Speaking Of Electric Heat. If So It Sounds As If You Are Not Getting 220 Volts To The Element, Only Getting 110 Volts. This Would Cause It To Just Get Warm. Suggest You Resumit Question With More Information. Sorry For The Trouble
Whats the problem? Blows cold air with the heat settings on?
No there is not. Whats the problem no heat ?? If so try this, reverse the heater hoses on the heater core and then go drive the truck and see if you get heat.
By heater element I am assuming you mean a heater core. If that is the case then you have one of two problems. Either the thermostat is stuck open and needs replacing or the heater temperature control valve is defective.
An advantage of an oil free heater is that it is more efficient and it will heat up faster than others.
The materials in a immerisian heater are used for making the heating element heat in water. Without them they couldn't be a chance for the heat to last.
Clogged Heater core... common problem with 2002 dodge
with a submersion heater designed for bath tubs..
Because metals are good heat conductors !
The water is not circulating through the heater core or you have a control problem. If the heater is putting out heat then it is probably a control problem. If no heat then - water pump out, low on coolant, or maybe the therostat is stuck open.
try the bend door
heater core....
Try the heater valve.
