If you have the 1978-1989 Chevy truck with a 292/4.8L you might be finding it runs a little hotter now.  You might also find heat cycling is occurring with your riser set-up.  We designed a impeller with an increased vane count and a reduced impeller vane clearance to take care of both problem.  It achieves greater flow rates, higher head pressure and a more efficient flow and squeezes that air out of your riser casting. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot 4.8L engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

Great casual watch
Color: Blue/Blue/Blue/solar
Has become my casual weekend watch. Can easily swap out the bands with no issue. I love that I no longer have to replace a watch battery.

Long time Timex ironman digital owner. First analog watch I've owned in a long, long time. LOVE IT.
Color: Black/Black/Black
Long time Timex iron man digital owner. First analog watch I've owned in a long, long time. LOVE IT. I don't know I'd go swimming or kayaking with this -- might be fine -- but for "dry land" this is a great watch, good band, for a reasonable price. It's battery powered, but that's OK with me.

Disappointing
Color: Black/Black/Black
Overall the watch is ok. The price doesn't reflect the quality of the watch. This should be a $20.00 dollar watch. I purchased this partially because I thought the number would glow at night, they do not. The hour and minute hand barely glow at night. I decided to just keep it, rather than returning it, and now I wish I had just returned it. After 2 months, I got a scratch on the watch, what looks like cheap, plastic. I can't say I would recommend it for that reason, I'm a average field watch wearer, which means they have to be somewhat durable. This was disappointing.
