Check both the heater core as well as the heater hoses for leaks...........
You have a leak in the heater core. The heater core is the only place that radiator water enters the truck cab, and both foggy windows and antifreeze odor are common indicators.
the heater core could be stopped up, or could be low of antifreeze, or the thermostat could be stuck open
sounds like your coolant lines, heater core, or both needs replaced. i just replaced the heater core in my truck with the same problem
Check both the supply and return heater hoses from engine to heater for blockage or clogging: remove them and flush. Also check the inlet and outlet pipes on the engine and heater core for gunk buildup and leakage.
First thing to check is open hood and feel heater hoses going into heater core located on r/s of vehilcle if sitting in driver seat.If they are both very hot and feel the same temp,blend door in heater box is not operating correctly.If one heater hose is hot and the other is cooler than chances are the heater core is plugged.In either case a professional would be your best bet for repair.Hope info was helpful.
To unblock the heater core, remove two heater hoses coming off of the engine going to the heater core. They are usually located on the passenger side of the vehicle near the firewall. Then use a high power water or air source to blow through the lines both ways.
1- Drain coolant. 2- remove heater hoses from core inlet and outlet pipes in engine compartment. 3-remove screws and heater core cover. ( right side lower passenger compartment ) 4- carefully lower core out of heater unit. This old of a truck it would be wise to replace both heater hoses. Use antifreeze as a lubricant to install heater hoses to new core inlets.
Gas heater & electric heater both are available.
it could be from your valve gaskets leaking oil. my car was smelling like that and my gasket seals were leaking, both front and back. after having them replaced i dont smell it anymore. KNOCK ON WOOD
Power flushing?? Any kind of flushing of the cooling system will clean the heatercore. They both use the same source of antifreeze.
The green colour is just a dye. Green antifreeze is generally referred to as "universal" antifreeze - it's accepted in a very wide range of motors, both petrol and diesel.
Yes , usually a 50 / 50 mix of antifreeze and preferably distilled water is used
