This engine does not rust from inside. It's aluminum. Remember also to use water that is demineralised. Coolant mixture is also important, because some other engines easily overheats when the mix is to fat. Thanks for a good video!
@@christianlarsen6421 Of course, people like me who use the coolant recommended by the brand are really stupid... I don't even know why the brands recommend it if water is much cheaper, and those cars with water in the radiator that looks like brick in a liquid state ? It's all myth and invention of people
@@lilPOPjimnope, it doesn't rust but you're correct that it oxidizes. I think the word you're looking for is 'corrosion' instead of "rust". As oxidation occurs, it hardens and creates a protective layer over the newly exposed areas of corroded aluminum. The aluminum corrosion process is actually halted by oxidation-the metal won’t continue to deteriorate unless the aluminum oxide is removed.
Yeah sounds like it just needs bled. Squeeze the flexible hoses in the engine bay and let the engine heat up to point where the thermostat opens and you can feel heat in all the hoses to indicate that coolant is circulating. There are plenty of other videos on TH-cam about coolant bleeding which go into it in detail including bleeding from the radiator cap itself. Normally for a Toyota the procedure I showed works fine.

The engine doesn't rust, but everything else does, from radiator, thermostat, and so on.
Radiator dont rust. Its aluminium ;)

Aluminium does rust. It oxidises just like steel or the majority of other metals. It's not as prominent as steel but it does corrode and rust. ..

There's loads of old coolant in the head still, always a good option to remove this and replace the thermostat for preventative maintenance :)
In all my time as a home mechanic I have never heard of anyone replacing a perfectly good thermostat for a new one for preventative maintenance.
Thanks fot he information by the way!
God don't need that information
You are welcome
3:21 what is that squeeze sound from engine?
Ive done this and now my car does not blow hot air? ive been told there is air in the system?

Hey there does the thermostat need to be removed?
Nope I didn't remove the thermostat.
