Robertshaw hi flow balanced sleeve thermostat for Gen 3 5.7L Hemi c.2003-2008Robertshaw thermostats do not fit all makes and models but we have modified the flange diameter to 2. 48" so they fit the 6. 2L Hellcat, 392 6. 4L, 6. 1L, and the 5. 7L Gen III Hemi engines. Why? Conventional thermostats for these engines open to 1. 36" but Robert shaw opening diameter is 15% greater to allow more fluid to pass through the heat exchanger (radiator) and cool the engine. You get more than just flow though. Robertshaw's unique three port

Robertshaw thermostats do not fit all makes and models but we have modified the flange diameter to 2.48" so they fit the 6.2L Hellcat, 392 / 6.4L, 6.1L, and the 5.7L Gen III Hemi engines.  Why?  Conventional thermostats for these engines open to 1.36" but Robert shaw opening diameter is 15% greater to allow more fluid to pass through the heat exchanger (radiator) and cool the engine.

You get more than just flow though.  Robertshaw's unique three port construction or "balanced sleeve" design equalizes the system pressures above and below the thermostat’s moving valve. Therefore the thermostat is pressure balanced and will respond to system temperatures only. No other thermostat does this.

Other Features of a Robert Shaw Thermostat:

1) Stress-free construction. Robertshaw makes the thermostat's strut assembly from  stainless steel using a technique to permit two brads per strut. Other manufacturers forcefully attach the struts to the housing with intense, metal-weakening pressure on the struts, binding each strut in only one spot.

2) The Power Pill®. This is the heart of a Robertshaw thermostat. It detects minute changes in the temperature of the coolant, and quickly activates a precision-engineered stem or piston to open and close the thermostat valve.

3) One-piece bypass poppet. With other thermostats, the bypass valve stem is welded on. The weld tends to fail under stress. To eliminate this problem, Robertshaw manufactures the entire copper cup and bypass stem from a single piece of metal.

4) Short-stroke piston. In conventional thermostats, the piston must make a large stroke to open the thermostat far enough for adequate coolant flow. But the long stroke compromises durability. Robertshaw engineers achieved a shorter stroke with a uniquely-designed flange and poppet. This design increases the longevity of the thermostat, yet still allows adequate coolant circulation.

5) Contoured strut. Making the strut assembly from brass instead of steel provides another benefit: brass, being more malleable than steel, can be precisely formed to maximize coolant flow.

6) Uniform quality. Robertshaw builds all thermostats to OEM standards -- so your replacement thermostat is identical to those used in new Fords, Chryslers, and other cars. The Power Pill At the heart of a Robertshaw thermostat is the power pill. Its job: to detect minute changes in the temperature of the coolant, and to quickly activate a precision-engineered piston that opens and closes the thermostat valve. Compared to the thermal elements in some thermostats, Robertshaw's Power Pill® has major advantages:

1) Rapid response. The Power Pill's piston is activated by a temperature-sensitive mixture of metallic powder and wax. Some thermostats use an all-wax charge, which responds slowly to temperature changes. Other brands mix copper powder with the wax for faster response, but the copper quickly separates from the wax. Robertshaw developed a process to maintain suspension of the copper powder in the wax, so the fast response doesn't deteriorate and the thermostat will not "stick-open" to cause the engine to run cool.

2) Reliable performance. Most manufacturers use a one-piece rubber diaphragm to seal the charge and drive the piston. If the rubber part ruptures, the thermostat fails. Robertshaw uses two separate parts: a diaphragm to seal the wax, and a stem seat or plug that drives the piston. Rubber material for each part is formulated especially to meet each part's unique requirements. Wear or damage to the stem seat still allows the thermostat to operate satisfactorily.

3) Precise performance. Every Robertshaw Power Pill is calibrated to bring the thermostat's start-to-open temperature within strict tolerances.

Lightweight, clean, and effective — worth the repurchase
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
This is my go-to daily sunscreen. It’s lightweight, non-greasy, and absorbs quickly without leaving a white cast. I love that it’s made with clean ingredients and doesn’t irritate my sensitive skin. The white tea scent is subtle and fresh. I’ve repurchased this several times now — it’s one of the few sunscreens I actually enjoy using.

Great replacement for my discontinued Epionce sunblock
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I really hate it when companies discontinue great products, and even though it cost a fortune, I loved the Epionce mineral sun block for faces. When I realized it was gone, I looked at the Coola line because I like their other products. Found this face sunblock for $32 (this could be 1/3 of the Epionce, certainly 1/2) and have used it for the past few weeks playing golf. So far, so good! I'm not noticing any color, certainly no burn. No irritation, and the scent is quite mild, only noticeable when it's first applied (IMO, and I'm pretty sensitive to scents). I really like that Coola has the Hawaii reef-safe designation, which I think is very important for all sunscreens, even when we're not going swimming in the ocean. As a friend pointed out to me once, even if you don't swim in the ocean, you go home and take a shower and all those chemicals wash down the drain and make their way eventually through the system, so might as well just not use them in the first place! Yes, it's more expensive using products like this, but IMO it's worth it. I also wear sun sleeves these days so I don't have to use as much sunscreen when I'm out on the golf course. Editing this to say that this product has avobenzone, which is actually not so great and may be banned in Hawaii by next year. Hmm. Guess I'll keep searching!

It works
Size: 1.7 Fl Oz (Pack of 1)
I invested in this for its travel size and my needs for a product that would protect my skin and not make it feel super oily. This delivers!!! I used it for a week in Florida with UV up to 11 on some days and didn't face a single issue, even after a Disney day. I was almost in disbelief at how lightweight this product is for it to work properly, but the protection strength is fabulous. I don't burn in the sun, but if I do, its typically along my face where the bridge of my nose is or my upper cheeks. This product basically said, "not today, sun." Bonus, it didnt burn or sting my eyes all day in Disney parks heat, and I didn't need to reapply even though I brought it just in case. Maybe it was the product or the Disney magic, but my skin also didn't look oily or shiny at all in my pictures with the product offering a nice matte finish.

seriously matte-ifying
Size: 1.7 Fl Oz (Pack of 1)
Don’t judge but back in the day I used to use Avon’s “face perfector” because it REALLY cut down on the shininess of face oil and it also had SPF. It made your face look matte without any other makeup. And I am pleased that this gel is similar. No face grease. It’s not even really a gel—if instantly feels powdery (somehow?) in your hand, thus it’s nongreasy. It leaves your face shine free and protected.
