Hi,

Starting to find out that maintenance is nothing like my previous BG!

Straight forward question - where is the drain plug to drain the radiator and replace the coolant?

I have looked at the back of the radiator and there seems to be no access because of the two fans. At each end of the radiator at the bottom there looks kike a plug at each end, with a rubber washer on but these look like items which cannot and should not be removed.

Any ideas please?

Many thanks.

Perriman.

Many thanks for that. Unscrewed the plug. However, when I measured the capacity of the drained fluid it came to 3.5 litres. The car users manual says the capacity should be 6 litres.

Is there is blockgage which needs to be cleared?

Regards,

Perriman.

I experienced the same difference in quoted capacity versus what actually came out of the radiator... I even ran the engine for a couple mins to see if more will come out since the water pump will be working. Some did, but still nothing close to 6 litres came out... more like 4 total

The only thing I could think of that would be a blockage is the thermostat, but its not currently installed so thats not it.... Perriman, that could be the reason in your case... maybe if u run the engine so the thermostat opens, more fluid would have came out

Thanks for your help.

I have replaced the coolant with a 50-50 mix of coolant and distilled water. I have just looked at the coolant and instead of blue, it is clear. Any idea what is happening. Is it likely that the fluid making up the 6 litres was in there all the time, and has now come through and diluted the fuluid i put in?

Many thanks.

Perriman.

Thanks for getting back.

Any idea how I overcome this problem of the thermostat shutting down, and retaining the fluid within the system?

There will be lots of coolant still in the heater matrix, behind the dashboard. It's 'uphill' from there to the engine, so it can't drain out from the radiator, unless you're He-Man and can pick up the back of the car and tip it out!

You can never drain 6L out if it as some of the fluid will remain in the block, hoses and the heater matrix.
It'll help if you switch the heater to full blast whist draining (key switched to on, engine doesn't have to be running) as this will move some of the coolant out of the heater matrix.
Although it doesnt make a lot of difference I also jack the car up on one side (opposite the drain plug) just to get a few more drops of old coolant out.

Thanks for your help. I,ll get as much out as I can and test it each week, adding some coolant each time, until I get it up to 50 -50.

Hi everybody,
Sorry if I'm being a bit dim here but I just can't seem to find this drain plug!
Can someone tell me what it looks like and exactly where it is on the Mazda 323F BA,
1998 Model 1489cm3 65kW/88hp engine?!
Is it behind some paneling that has to first be removed?
I can't see anything that looks remotely like a drain plug!
Many thanks, I'd be most grateful for any tips!

If your F have fog lights the plug is visible from the front just below the right fog light. It can be unscrewed either with a 10mm socket or a + screwdriver..(use the 10mm socket)
If you have no fog lights there is a plastic cover in place of the missing fog light that needs to be removed so to be able to see the drain plug.

Hey wow thanks a million for taking all that trouble!
Absolutely spot on, even I couldn't miss it with that :D !
I'd been looking UNDER the car the whole time, duh!
And you're right... the 10mm socket is way better than the + screwdriver!
