## Questions & Answers

**Q: Will this valve stay in each position without a cable hooked up ? Could I just pop my hood to change it each direction?**
A: Not likely. I ended up installing a locking cable so I could lock it either open or closed. The force of the coolant flow was pushing the valve partially open and allowing coolant flow through the heater core with a standard push/pull style cable. I highly doubt this valve will stay shut without something holding it in a set position.

**Q: I need a valve to fit my 1957 ford fairlane heater core due to the one on my car's o rings are worn out and leaking, do you have a replacment?**
A: I own a 66 El Camino and used this successfully to isolate the heater core during the summer. It is really universal and just attaches to your existing heater hoses before they attach to the heater core thus, bypassing the coolant back to the engine.
I hope this has been helpful and good luck.

**Q: If I turn my heat selector to hot, and the cable retracts, do I need the push or pull valve?**
A: If the cable retracts then you need the pull valve.

**Q: Will this work on 1997 - 2003 f150 or expedition? is this better than just dong a "u" shaped heater hose bypass?**
A: I am not familiar with ford truck heaters , mine was used on a hot rod , to control the heat from inside the cab . It works great for that function . The only thing I would want to be aware of ,would be the size of the hoses attached to it . I believe all the valve ports are 5/8 inch ,but it comes with 2 adapters to 3/4 inch .

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fits
*by J***O on February 13, 2023*

My chevy luv heater control broke and would leak everywhere. There are no stock heater controls in any store. I saw someone talk about this control valve online and decided to give it a try. It works perfectly in my truck and the heater blows hot. I still need to find a way to adapt it into the truck since it obviously not made to mount under the hood. Overall great buy.

### ⭐⭐⭐⭐⭐ nice and toasty
*by R***E on March 26, 2024*

Bought this for my Subaru swapped Vanagon. This valve does what it is supposed to do. Keeps the Subaru engine happy and keeps the heat out of the cabin when I don't want it.

### ⭐⭐⭐⭐⭐ Best Coolant Valve So Far
*by C***1 on August 16, 2024*

Installed to a 1966 Ford F100 with a Classic Auto Air conditioning system to help regulate interior temperature. The best so far. It's hard to regulate temperature with coolant flow since engine speed is always changing.
