Why is my truck not blowing hot air?
Faulty Heater Core The heater core looks (and works) similar to your car’s radiator — it’s made up of a series of narrow tubes and fins. Faulty heater cores and low or contaminated coolant levels often come hand in hand, and both issues may lead to your engine overheating and your heater not blowing hot air.
What causes a clogged heater core?
Heater cores don’t normally clog up on their own. It’s usually caused by an outside force. If you run straight water in your cooling system or your cooling system is full of scale and rust, your heater core can clog up. While the engine is cool, remove the radiator cap and inspect the coolant.
Is bypassing a heater core bad?
Bypassing the heater core will effectively prevent the leak from happening but it cannot undo the damage that has already occurred as a result of the leak. There is probably a fair amount of coolant or water inside the heater core already in places that it wasn’t meant to get to.
Will vinegar clean a heater core?
Vinegar is an acid, but is mild acetic acid and typically 5% such. It’s perfectly okay to use it alone to remove system rust if you just add a gallon to the system and run the car a short while, like 10 -20 mins, including turning on the heat to clean the heater core.

Can you reverse heater core hoses?
It’s important to identify the inlet hose because you’ll want to reverse flush the heater core. By reversing the hoses, the coolant will flow in reverse direction through the core, but it’ll still be flowing in the same direction as far as the engine is concerned.
Is replacing a heater core expensive?
Replacing the heater core can be an expensive job, and usually costs between $564 – $927 for parts and labor. The parts aren’t particularly expensive, normally costing $80 – $234, but the location of the heater core means that labor costs tend to be quite high.
