A thermostat helps getting your transmission up to optimal temp quickly, and keeps it there.

The only thermostat with a patented design that closes 100% when you need it to.

With a correct sized oil cooler kit, you with have full temperature control on your transmission.

The termostat opens up about 10c lower than most OEM thermostats, giving you better control of your transmission temps.

The typical stabilization temp is 74C (165F)

Activation temp is 71C (160F)

Full flow temp is 83C (181F)

 Please add ptfe hose ends for a complete install with our oil cooler kits.

Improved Racing's Flow Series Compact (FSC) oil thermostat is an ultra-compact unit designed for use in cooling systems for transmissions, differentials, transaxles and small engines where flow rates do not exceed 5 GPM. This thermostat is perfect for engine oil cooling in motorcycles, ATVs, go karts, and other small engines.

The device's unique, patented internal design (US patent 9,772,632) ensures a low pressure drop by placing the bypass valve mechanism completely out of the primary oil flow. This arrangement also allows for a compact design.

Without a thermostat, oil and transmission fluid coolers are likely to over-cool the fluid, delaying engine warm-up and resulting in horsepower loss, excessive engine wear and reduced gas mileage. Oil thermostats perform the critical function of bypassing the cooler until the oil has reached its minimum operating temperature.

The thermostat maintains the oil exiting the engine at the rated minimum temperature in most conditions

 

  • Reduces excessive engine wear and horsepower losses while improving gas mileage by preventing oil temperatures from dropping below optimal levels
  • Patented, high flow, low pressure drop design locates the valve assembly completely out of the primary fluid flow
  • Maintains a minimum fluid temperature according to the typical stabilization temp in the table below, +/- 2°F (+/- 1°C)
  • Allows a small percentage (less than 10%) of fluid to continually circulate through the cooler to eliminate air pockets and prevent cold fluid trapped in the cooler from shocking the system
  • Rebuildable
  • 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish
  • Lightweight at just 7.5 ounces (212g) without brackets or fittings

An excellent replacement for the old camper watch
Color: Black/Black/Black
I wore Timex camer watches for much of my adult life. I prefer the analog wind-up versions, but they are not widely available at a reasonable price. I purchased this model for its large easy to read face and durable strap. The Indiglo feature is a bonus.

Favorite watch / solar
Color: Green/Green
I'm partial... I have bought Timex my intire life, they no doubt make the best watches... They take a licking, but keep on ticking is there old commercials.. True.. Great quality, keeps going after many year's... I never bought a solar watch from them prior I have to mention... It should hold up I'm thinking like their battery watches, I hope so. My favorite watch, I own a handful. Watch looks better in person... Downfall, they are trying a new band out of recycled plastic, I don't like it as much as the older bands it's soft, but feels a little strange...

Solar powered
Color: Green/Green
Great watch for us older folks. The hands are large enough to see easily and the fact it is solar powered means batteries do not have to be replaced every year or two.

Nice watch
Color: Green/Green
Very happy with my purchase, rated the purchase with 4 stars due to the band being very stiff, holds doesn't line up to fit wrist properly, don't recommend for seniors to purchase, very difficult to put on.
