Installation / Use / Maintenance Tips
- Drain the cooling system completely before removing the old water pump to minimise coolant loss and contamination.
- Clean all gasket mating surfaces thoroughly and use the supplied gaskets and seals — do not reuse old gaskets.
- Inspect the thermostat, radiator hoses and drive belt while the pump is accessible; replace any worn components at the same time.
- Refill with the manufacturer-recommended coolant type and concentration, and bleed all air from the system before starting the engine.
- Run the engine to operating temperature and check for leaks around the pump housing, hose connections and bleed points.

Not a G but just as good IMO
Color: Green, Style: Modern
Solar, mineral crystal, excellent color (mine is green) - almost the perfect watch. Big but light and comfortable. Good for old person eyes, easy to read. The digital window is hard for me to read but "its there". Its not officially a G-Shock but its touch, Solar and waterproof so I am just as happy and the price...$$ is right.

Casio Tough Solar No Lighted dial, Just Date Box
Color: Green, Style: Modern
A picture of how it lights at night would kill all sales if anyone needs a good readable watch in the dark with a lighted dial as the description says. Just the little LCD insert lights up so it shows just the day and seconds. I guess the date of the day can't fit in the little rectangular LCD insert. I collect watches and this Casio Tough Solar is a superb analog dial watch for working with. This one is solar, so the price is good for that feature, as most Casios may be quartz battery types. This one is for an off shore sea worker so it will stand up to the tough work he does. I wore my Casio, a digital solar, for 14 years now and I build, work hard and these watches from Casio can last surprisingly long. Other brand watches would finally give out for one reason or another as a work watch. The price for this one is affordable for a simple but tough watch that will last over a decade, maybe two.

Best Value Field Watch
Color: Green, Style: Modern
I am a deployed military person. I bought an expensive "field watch" for over two hundred dollars. It broke after being dropped once. I ordered this watch as a temporary watch to use until I can get home and get a replacement for the "expensive" watch. I can tell you without a doubt, this is a much better field watch than the 200+ dollar watch. It has a large face that is easy to read on the move. Although the viewing area for the face is large, the watch is surprising light. I wear it while exercising and doing military duties. I recently competed in a 15 mile ruck run and didn't even notice it on. Probably the most comfortable watch I have ever had. The lumination on the hands and numbers is pretty impressive for the price, and is very visible for a few hours. The digital portion gives you options of timer, stop watch, date, other time zone, and alarm. I am far sighted, so the digital window can be hard to read while moving or when using the light. If I have my reading glasses on, there is no issue. For military personnel, the light on the watch only works on the digital display, and therefore gives off very little light while still making the digital time very visible. You can easily maintain light discipline and check the time, timer, or stop watch without creating a glow like other watches do. I usually don't wright reviews, but I love this watch that much. It gives you the best of an analogue and a digital watch in a light, comfortable, dirt cheap package.

The AQS810W (5208 module) series is one of Casio's best, in terms of being durable, reliable and problem-free.
Color: Green, Style: Modern
This is my second AQS810W... my first is about five years old, and it's black with white lettering. The "Tough Solar" and "Illuminator" are long-gone, rinsed away by automotive degreasers and other auto repair chemicals, but I like it better without those pronouncements, anyway.
Army Green, in my opinion, is an excellent color on this watch. The fact that this is not at all a glossy watch, but a matte (or semi-gloss?) finish makes the color attractively subtle. I like it even more than the black.
Other than the color, though, it's the exact same watch I've been very happy with for the last five years. Easy to setup, rugged and sturdy, just the right size (for me) and an industrial, utilitarian look.
This is a very comfortable watch to wear - light in weight, flexible band, no sharp edges or uncomfortable shapes.
I spent a few weeks trying to decide what watch I was going to get, and I came to the conclusion that being solar-powered was my highest priority, followed by being quickly readable. Perhaps it is just me, but I can read a analog watch faster than a digital one - just a quick glance. I kept coming back the Casio's AQS810W series, and it came down to the darker, matte-finished colors.
Having said all of that, this series of Casio watches is virtually trouble-free. Read the reviews! VERY FEW failures, defects, water intrusions. People who don't like this series of watches either find them incomprehensible to set or are unhappy with the small digital display or the lack of a backlight for the analog dial. The watches themselves are largely bulletproof, possessing anvil-like reliability and durability. They even have a feature that if the watch is dropped or knocked around too hard, and the analog hands get out of sync with the digital display, you can quickly and easily re-sync them.
This series is one of Casio's best, in terms of being problem-free.
Yes, they have acrylic crystals, not mineral glass, and they do scratch. Simply buff the scratches out, and it is as good as new. Worried about the band breaking or falling apart? On a regular basis, take the watch into the shower and scrub the whole thing with an old toothbrush and some shampoo. Not only will it be clean and look great, but removing the body oils, sweat and salts makes the bands last and last. That's the secret to getting Casio resin bands to live long lives.
The analog dial is not lit, but neither is the dial on my Rolex or Omega. Just find a light source to reflect on the hands, and you're in business. Just like we've done for many years.
Anyway, you can tell I am a fan. Buy with confidence, but download the pdf version of the Casio 5208 module operating instructions, and it'll be easier to set up the watch if you aren't very tech savvy. If you like the way this series of watches looks, then I'm pretty confident you'll be very happy with your purchase.
Have fun!
