Check my water today and its bloody orange. What could cause the rest in the water and what would anyone recommend to do?


Thanks

nothing unusual about rust in the radaitor. You have big lump of cast iron under the bonnet called an engine and it will turn the water brown quite easily and even shed rust flakes if the coolant has not been changed for a time. You need to buy some decent cooling system flush and follow the instructions to clean it up. Then fill with coolant of the correct concentration which has rust inhibitors. If really bad it may take a couple of treatments to clean up.

Insert a bottle of hair shampoo. (For oily hair may be best, but anything.)

Run for a week or so.

Flush out (keeping in mind thermostat is closed if water cold).

Refill with coolant - I recommend water and concentrate.


Warning - there are 33% "[I[concentrates[/I](sic)" and true 100% concentrates.
Pre-mixed coolants/inhibitors are often only ~7%.
Do the math - the "expensive 100%" concentrates are cheaper. And it's easier carrying a 1L bottle than 4L etc.
But I usually start with 30-50% mix and just top up with plan water.

To flush i usually remove the top radiator hose from the radiator and route it to the ground, sometimes you might have to hook up something else to the hose.

Plug up where the hose went on the radiator. Stuffing with a rag usually works.

Set up a running hose. Trigger hose but at a fairly low pressure, flow rate.

Then run the engine, you will have a dribble of water when the thermostat is closed and a gush when it opens.

Keep topping up the radiator. Handy to have an extra person around to adjust the tap should it need it. Point the hose away and pull the trigger to get rid of the pressure spurt then top the radiator up.
Its a bit harder in the Piazza or similar vehicles to get an idea of how full the radiator is when you can not look down in the radiator and see the core. When it flows out the top that means its full.

Dont put cold water in the radiator in an engine that is not running.
Can crack the block.

Dont put cold water on the engine block of an overheating engine. Can crack the block.

If your engine is overheading the bist thing to do is to run water over the radiator, that will cool it down. (but dont give a motor with points ignition and a fixed fan a big rev, that will wet the motor and it will stop.

np. thanks for the tips. I get on to it this weekend. I got another problem now, well it had it since I bought it.

It leaks fuel every now and than. Mainly when its just started and than it seems to go away after 5 min.

Its dripping from the fuel pump so it seems but when I lifted it up and checked everything it didnt happen and I took it to the mechanic once and it didnt drip than either. The mechanic checked the pump and hoses and there fine.. he said it might be from the petrol tank. Has anyone had this problem before?
