SOURCE: Losing coolant thro the expansion

Not too familiar with this model but.... First some questions! Has the fault started after the pipes & rad replaced or were they replaced to remedy problem? If fault happened since work then i'd suggest an air lock in the system in which case you will need to 'bleed' the system of air. Make sure the expansion tank is the highest point & look for any bleed valves on the hoses - usually near the heater matrix. Sometimes it may be necessary to help the process by removing the temperature guage sender unit to allow the air to escape as air cannot pass through a closed thermostat. If the fault was there before, does the expansion tank seem to build up pressure very quickly? Do lots of air bubbles appear with the engine running & the pressure cap off?

SOURCE: I want to know how many litres of fuel are required to travel 625

Hi there,

For the purpose of answering the above question:

625 km, divided by 100 km = 6.25 km per every 100km of fuel.

If your vehicle consumes 11.1 litres per 100km's. then 6.25km x 11.1 litres = 69.4 litres required to travel 625km's.

Please Note:
if your vehicle has an onboard trip computer, this data will fluctuate roughly every 10mins (computer processes data) depending on the nature of your driving and whether you are on a highway etc.

Consistent driving on a highway (i.e. no stops, no acceleration or turning) will give you the highest 'distance to empty' reading.

Driving around city (i.e. constant stops and accelerating) will give you the lowest 'distance to empty' reading.

If you are interested in determining your vehicle's true fuel consumption, the best method is the fill & re-fill method:

1) fill tank to full
2) cancel the 'trip meter' on your speedo to "00000"
3) drive until you have less than half a tank (or near empty if you prefer)
4) return to the same fuel pump (that you filled with) and fill tank again
5) record the "litres of fuel" you have just purchased (to fill your tank again)
6) record the kilometres you have just travelled on your speedo 'trip meter' at time of refilling.
7) divide the total litres by the kilometres travelled. This will give you the litres per 1km. Multiply this by 100, to get the litres per 100km (average).

What is the volume in liters of a water tank with ....... radius 2 feet 6 inches height 5 feet 2 inches

Assuming you are correct that the radius is 2' 6" and not the diameter.
Convert the inches to centimetres
1" = 2.54 Cms
Radius = 2' 6" = 30" X 2.54 = 76.2 Cms
Height = 5' 2" = 62" X 2.54 = 157.48 Cms
Volume of cylinder = Pi x radius squared x height
3.142 x 76.2 x 76.2 x 157.48 = 2,873,038.9 cc
Divide by 1000 to find how many litres (interest note 1000cc car engine is 1 litre)
2,873,039 cc / 1000 = 2,873 litres

I just purchased a 2016 Mazda 3 Touring. I was informed that I would get a combined fuel of 5.7litre to 100 kms and also the tank is 51 litre. . Only got 390 kms to empty took only 40.5 litres! 10 l

the fuel consumption figure is what mazda get in a factory controlled test operation and is only an indication of what can be expected with careful driving
they have no control over driving habits or traffic conditions and drive speeds as the variation is too great to even talk about
by the calculations you are getting 5.6 liters per 100 klms so where is the problem
to get exact figures for your driving habits
you go from tank full to tank full and divide that into the figure set on the trip meter when filled the first tank, not what you have calcuated

It's taking a few minutes for the pump to take effect when turning on the tap is that normal?

If you are referring to a water well pump it is possible for it to take time before it starts. The pump is most likely connected to a holding tank and has a pressure switch on the sys. The switch allows the pump to turn on at a low limit and shut off at a higher limit.

Water is constantly getting into my diesel. There are no leaks in the diesel tank. Can you suggest where the water is coming from

I'd bet your tank Cap seal is not good. Lots of rain? And or moisture is condensing inside the tank. Another thing to check is the fuel return line from the injection pump to the tank is properly sealed. Water in injection system is deadly especially to the pump. So find the problem soon. you may want to put "fuel dryer" (methanol) to remove any residual water. Oh, Did you stop along the way? Is the cap locked? Or lid locked. With that much water you may have had some vandalism. Any enemies?

    Installing an air pump in a 5000 litre tank

    The pump must be mounted nearest the 5000 liter tank. The air intake will be the air sorrounding the area, while the discharge low pressure air must be pipe to underwater level such that the air discharge of the air pump bubble up the water (aerate the water) inside the tank. This is common in fish pond/ shrimps pond/ and water treatment plants. Electrical wiring is
    standard for the electric motor and controls.
