Why is coolant not returning to the engine as the engine cools?

i would say if the coolant is getting hot in the engine but not flowing threw the radiator to cool the engine down the thermostat is stuck closed and not letting the fluid pass OR Ive also heard that if a air bubble gets caught in there it wont feel the hot fluid and open to flow the coolant threw the engine im pretty sure in the z31 the thermostat is behind the pulley that goes to the a/c pump you have to take that off and you will see were it goes in the engine i would change that out and see if that fixes it

What an engine cools better water or coolant?
Coolant I believe.
What does the fan do in a car engine?
cools the engine. without a fan, the car will overheat and the coolant will boil. the fan controls this from happening by cooling the coolant as it passes through the radiator.
How Oil cooler in an aircraft engine work?
An oil cooler works the same as a radiator that cools coolant
Is there always coolant in the overflow tank?
Yes. There should always be some coolant in the overflow tank. Its level should rise when the engine warms up, and it should go back down when the engine cools.
Does coolant flow through reservoir?
No. The reservoir holds the coolant that flows back into when the engine coolant expands and will flow from the reservoir to the engine when the water cools. but there is no actual through current of liquid. Yes indeed it does on a lot of European vehicles. This occurs mainly in automatic coolant bleed vehicles.
Does water in the reservoir circulate through radiator when engine runs?
No. When the engine is running coolant is heated and expands. Excess coolant then flows from the radiator to the expansion (overflow) tank. When the engine is shut down coolant cools and contracts drawing fluid back out of the tank to keep the radiator topped off.
How long should you wait to open a radiator cap if engine overheat?
Until it cools down, which will be an indication that the coolant has depressurized.
Is Coolant the same thing as Anti-freeze?
coolant/anti-freezeYES, BUT ALL ANTI-FREEZE IS NOT THE SAME YOU NEED TO CHECK YOUR OWNERS MANUAL TO SEE WHICH TYPE YOU NEED. The words are sometimes used interchangeably. However, if you live in an equatorial country, your coolant is more likely to be water. I.E., Engine coolant is any liquid that cools the engine by dissipating the coolant temperature through the engine's radiator.
When my engine cools I am losing water coolant apparently not from a hose or direct from leaky radiator what can be the cause?
This sounds like bad news. The coolant could be leaking into your engine and mixing with the engine oil, then cooking off. A simple test can tell if there's water in your oil.
Your car does not run hot but it bubbles when you turn it off?
It is normal to boil when you turn the car off. When the coolant stops flowing, the coolant in the hot engine boils and pushes steam out of the engine. The recovery tank collects the excess and allows it to go back in when the engine cools.
What does coolant mean?
A coolant is something that cools a machine so it will not overheat. This also can be used in regards to animals, for example sweat that cools the body.
What part of the car cools the engine?
The radiator cools the engine.
