Does revving your engine make it warm up faster?
Long answer: if you are in a situation where you need to rev your engine to make your AC cooler, you shouldn’t be revving your engine. AC is unaffected. Heat does warm up faster but revving your engine too high when it’s too cold can be harmful.
Why does the temperature rise when the car is not moving?
When you start driving air is flowing through the radiator and cooling the engine. The fans should be doing that when the car is not moving, but for some reason they’re not. Check the fuses for the fans first. If the fuses are OK you’ll have to start checking the fan relay, the wiring, and the fan motors themselves.
Why does the temp rise when the engine is idle?
Start the engine and let idle while at the same time watching the temp gauge. As the temp gauge rises, check to see if the radiator fan engages. If it doesn’t, there’a a problem in the fan circuit.
When do engine revs rise when changing gear?
After driving my New Vectra for almost a week now I have noticed that when I change gear (when the engine revs build up to around 2 -2.5k) the engine revs rise up by around 300 rpm when I dip the clutch. The revs fall to the idle speed after a second or so.
Why is my car revving at high RPM?
Also possibilities are vehicle speed sensor fault, clutch switch, power steering pressure switch – all of these could request a high rpm if faulty. Best option would be to get the fault codes read out, that should identify the cause. All the above is wrong. Exocism will resolve the problem.
What happens if you rev your engine before warming up?
If you rev your engine before it’s been warmed up the oil may not be able to properly lubricate the engine which means more wear and tear on the internals. In general, the more wear on the internals of an engine the shorter the life of that engine, but revving the engine in your car is fine as long as it’s been properly warmed up.
What happens when you rev your car to high rev range?
Your engine will be most efficient and use the least amount of gas while at idle. So anytime you rev your engine to the high rev range you will be using more gas than you would if you let your engine idle.
When you start driving air is flowing through the radiator and cooling the engine. The fans should be doing that when the car is not moving, but for some reason they’re not.

Why is revving the engine bad for your car?
Revving out the engine in your car can be bad for the engine if it’s internal temperature is still low. On a cold start, the internals of an engine hasn’t had a chance to properly warm up and the engine oil is still cold which means it won’t flow as well.
