Warm up the engine??

[Ry_Tower]

As per owner's manual, let the rpm settle sa normal idling level. During start, >1k rpm tapos bababa about 800 rpm in a few seconds

Ganyan sa gas engines, sa diesel may 1 minute talaga na ideal warm-up even with a fully functioning thermostat. Mas gusto ng diesel na medyo mainit kunti eh.

I always warm up the engine ---- I never load the engine until it is in its working temperature.

Simple as that

^^ agree ... 5 mins is too much

thanks Ry ... im about to ask about diesel engines

think in wintertime, they warm up the engine also because the engine coolant is used in the HVAC to heat up the passenger cabin. It usually takes a few minutes for the engine to become warm enough to raise the cabin temp.

maybe so, and that is just to help to warm the cabin. but in terms of idle time or waiting for the oil to circulate before driving, any more than 5mins is just a waste of fuel.

Mahirap magdrive kung nanginginig ka sa lamig. Kaya antay muna uminit cabin.

Modern engine doesn't need too much time to warm-up, 30 seconds max before driving away:

"In winter, don't idle a cold engine for more than 30 seconds before driving away."

^ for both petrol and diesel?

What's often forgotten is that idling warms only the engine – not the wheel bearings, steering, suspension, transmission and tires. These parts also need to be warmed up, and the only way to do that is to drive the vehicle. Until the engine temperature begins to rise, it's a good idea to avoid high speeds and rapid acceleration.

Paano if you're not using the car for at least 3 days?

[dfopiso]

^ sa lumang auto, longer time to warm up ang gawa ko

[sotel]

sa lumang liteace ko palyado pag hindi na warm up.
kahit 1to2mins lang na warm up ayos na

Same ng post ni Noel. Warm-up engine by at least 1-2 mins. and then drive slowly muna to make sure differentil oil, tranny oil and other mving parts get a good warm-up as well.

It's always better to warm the car up vs. not warming the car up. Kahit 2mins lang. - For diesel engines ha. For gas, seconds lang.

with today's cars, close tolerances between the piston and the cylinder bore, close tolerance between the crankshaft and camshaft bearings, there is no need to warm the engine up. the radiators of yesteryears had three rows of cooling tube versus today's with only one does not need the traditional warmup. it was so designed to save fuel and increase the mpg rating of the car. even the oxygen sensors have shorter time to get to closed loop because of the heating element inside the oxygen sensor itself. parts have been lightened (again for fuel economy) and gets to operating temperature faster. with some purely air cooled engines, the moment the engine runs, it is as warm as operating temperature. the problem though, with the designed short to no warm up time needed, is that the engine overheats if the cooling system is not properly operating: i.e. no thermostat or stuck closed thermostat, radiator cap that can not reach the required pressure, wrong type or wrong mixture of the anti freeze coolant, insufficient airflow to the radiator, air pockets in the cooling system that had not been bled, over advanced ignition timing, clogged exhaust system and vacuum leak at the intake manifold. today's car are made to be driven as soon as the engine starts.

parang tao din yan eh, bago mag basketball, warm-up at stretching muna.

1994 Nissan Vanette Z20S Engine. Local.

Thermostat was removed by the previous owner as well as yung fan clutch-nakarekta na.
Every morning, 1-2 minutes of engine warm-up before I drive or else engine will stall.

As jeck says.

The one thing you should not do after starting up a cold engine is to race it (ie. aggressive throttling, acceleration and/or red-lining). Otherwise, you can drive the car as you normally would.

If we're going to use an athlete's body as an analogy, a warm-up exercise means running a lap or two around the court, doing jumping jacks, etc. You don't warm-up just sitting down doing nothing. Somewhat the same with cars. You warm it up by "stretching its legs" and just be on your way.

what i do for my mb100 is to idle it for 1-2 mins then slowly drive it off

right on the button.

ae101 ko, 30 - 40 seconds,
para lang umikot ang langis ng konte,
then i start to roll, and shift at low rpms hanggang
umabot na sa operating temp.


pero pag hindi nagamit yung car ng more than 3 days,
paabutin ko din ng 1.5 minutes, para malangisan ulit mga
singit2x ng engine internals.
