Water Restrictor in Radiator Hose: Cool Down or Heat Up?

AI Thread Summary
Installing a water restrictor in the top radiator hose of a car engine can lead to increased engine temperatures due to reduced cooling system effectiveness. While it may cool the fluid within the radiator, the overall impact on engine temperature depends on the specific engine and cooling system's thermal efficiency. If the coolant cannot adequately draw off heat while circulating through the engine, overheating could occur. Additionally, there is a risk of damaging the pumping system. The discussion highlights the complexity of the issue and the need for careful consideration of the cooling system's design.

You would not lock threads where i tried my best to put my point of view. I,m not a crack pot

OK let's argue about something that I actually have experience with. You all seem to be terribly set in your ways in fact a bit too arrogant for my liking

So the question is : If you put a water restrictor in the top radiator hose of a car engine, will the engine cool down or heat up?

That was a valid physics question.

Drop the attitude, you agreed to the rules on sign up. If you don't like them go elsewhere.

You would reduce the effectiveness of the cooling system and the engine temperature would increase.

EDIT: I suppose you'd also increase cooling within the radiator itself, giving cooler fluid moving into the engine. So we'd need to know how much cooler it would become and compare this with the thermal efficiency of the coolant to see if it could draw off the required amount of heat whilst traveling through the engine.

If it's cool enough and can draw off the heat well enough it could cool the engine more, if the additional cooling isn't enough or it can't draw off the heat then the engine temperature could increase.

I think it would depend on the engine and cooling system.

You may even damage the pumping system.

Also, it's "If you're so smart".

So it isn't to your liking here? Taking part in this forum isn't compulsory. There are plenty of car mechanics' fora elsewhere.
 
In before the lock.

If there was a definition of ownage, this would be it.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
