Fluids not circulating properly until the engine is revved too

very true. i changed a stat on saturday, refilled and put it all back together, started it, came back 10 seconds later to check what was being returned to the expansion tank and saw nothing. pulled the return line off to see if it was blocked (it wasnt) and the system was full... it just wasnt circulating until i revved it and all was fine
 
Maybe in the 1920's it was bad to sit with an idling engine but technology has moved on. Oil is better, fuel is better and engines are better managed.

It's only supposed to return to the expansion tank when there is too much pressure. When it's idling that water is circulating inside the engine without the need to return. The tank is only there to hold a little extra water in case of a slight overheat and to allow for the expansion of the water when hot.

ive been mucking abotu with vws for years, water should be continuously flowing back through the return line, if its not they end up with big airlocks etc

they self bleed that way
 
Post 23 someone mentioned bette roils and fuels and you said in your smart arse way " proof please"
Correct me if im wrong

only when they are hot. When cold there is no need for them to return to the "EXPANSION TANK". It's all in the name. It's not a circulation tank. It's function is to allow for the expansion of water when it is heated. The returning water to the header tank is a byproduct not a requirement
 
So you're avoiding the real question with pedantry. He was not requesting proof that technology has moved on, but rather than cold idling was a problem in 1920 and not now.

Let me help you move out of this trolling loop. Proof of the aforementioned, please?
 
IF it's bad for an engine to sit there idling when cold in terms of wear and tear, which I doubt it particularly is, it's even worse to drive off before you can properly see through the windows.
 
This is shocking, can someone not source somewhere reliable which advises the proper start up behaviour?

Im of the belief that it does no harm, it will warm the engine up slowly... (im thinking about modern cars >1998)

Cars and engines are a lot better now than 90 years ago, I dont need to prove any of that. As are oils and fuels etc.
 
I'm not oil engineer, but I would imagine regardless of how new the oil is - it still works better at full temperature, that and the possibly lower/uneven oil pressure in a higher mileage engine at idle wouldn't help. My Rover 75 Diesel has a fuel burning heater, a £500 item, for the sole purpose of helping the engine warm up - so it must be of some use.
