Toyota 4Runner owners from 1998-2002, listen up! If you're having issues with your heating system - maybe it's not blowing hot air, or the temperature control seems wonky - this HVAC Heater Control Valve might be exactly what you need. This is a direct replacement for part number 87240-35070 (also works if your original part says 8724035070).
The heater control valve is basically what regulates the flow of hot coolant to your heater core, which is what gives you that warm air on cold mornings. When this valve goes bad, you might notice no heat coming from your vents, or the temperature not changing when you adjust the controls. Not exactly fun when winter hits!
Installation is pretty straightforward if you're comfortable with basic automotive repairs - it's usually located in the engine bay near the firewall. This replacement part is designed to fit perfectly with your 4Runner's existing mounting points and hose connections. Whether you have a 1998, 1999, 2000, 2001, or 2002 model, this should get your heating system working properly again. Much cheaper than taking it to the dealer, and honestly not too difficult to replace yourself if you're handy with tools. Stay warm out there!
