Flushing the Radiator Part 2

So, after running the car for a few days, it was time to flush the cleaning chemicals out. I had to let the car run for a few minutes first so that well, the sediments would mix with the cleaning chemicals again.

Once the engine is more or less cooled down, I had to untwist the plug located at the bottom of the radiator. Because the engine was still hot, I could not stuff my fat arms inside.

See that little yellowish butterfly? I has to crawl from under to untwist it to release and drain the hot water from the radiator

This is the part where I start to worry. The total contents that came out from the radiator was very much less although there were quite a lot of what I suspect would be rust particles.

After letting the water from the hose run, I started the engine again. This would help the fresh water to circulate a little.

This kept on until there were no more suds left.

At this time, I remove the 10mm bolt holding the reservoir bottle as I wanted to clean it too.

There was sediment in there as well

I ma using Toyota Long Life Coolant. But after talking to my Techs the other day, they preferred I use Perodua's own brand as this is one kinda a little harsh to the system

After pouring the whole bottle to Toyota long Life, I realised that the radiator could only hold less than 2 litres. At this time, I also forgot to put some into the reservoir. I wanted to get a 1:1 mix but I only managed to add in about 800mL of battery water

Well, I am quite disappointed as the whole exercise did not reduce the temperature but to a smidgen. Still I'll drive around for a few days to see if there is any effect.


The temperature did not really go down much but I'll drive the car around for a day or two to see if there is any changes. Still, despite all these, the only thing else I can do would be to change the aging water pump and based on Internet prices, they are not cheap. I suppose I will do this after replacing the head gasket.
