Right now int cold in TN and I was wondering how long it takes everyone's car to warm up in cold and hot weather. It takes mine a while to hite the second mark past c.

 

it takes anywhere from 5-7 mins for the choke to pull itslef in and another few mins to get fully warmed up. oh yea, its around 30-35 degrees in the morning right now.

 

In cold whether mine takes a while to even reach the 40 mark if im just at idle. Its mostly because my Fan is always on (Put a bolt right through the clutch)

 

yea, last winter when i had the messed up fan that always stayed on it took like 15 mins to warm up and even then it wasn't all the way, it was a real pita.

 

mine use to take about 20 to 30 minutes to warm up completely.

 

Until my car is warm it drives like crap. Then after that it doesn't idle (bad tps). It does like warm weather though.

 

If I let it sit with the choke on fast idling around 2.5K, about 5 minutes and the choke pops off. If I take off after a minute of fast idle and drive off with the choke on, it doesn't get fully warm for about 15-20 minutes, and seeing how that is how long my morning drive is, it may never get fully warm. The moral here is to just let it sit and warm up patiently. After I manage to get it started and it doesn't die on me, I go in and brush my teeth and make sure I didn't forget anything and kiss my wife and daughter goodbye. That's about 5 minutes. Its been really unusually cold here overnight, down to 10-15 degrees overnight. Normally its around 30-35 overnight this time of year, down to mid twenties later this month. Good for duck and goose hunting though

 

Well I don't mind my Fan being always on just because i know my car will never overheat. Also i don't drive it in the Winter anymore so its not too big of a deal

 

Yeah, but isn’t the fan suppose to disengage at higher rpm? It must be really loud, and probably slows down your acceleration.

 

I replaced my carb pre-heater hose, the one from the exhaust manifold to the aircleaner, and it really cuts down the warm up time. Definately a must have.

 

no **** its freezing im in rockland ..lol
frost like crazy

 

It is supposed to under a certain RPM - in the low 2k's. It sounds pretty cool when it's engaged though

 

In the recent 30-40 degree New Jersey morning weather, my choke will
pop in after 5-7 minutes. After starting, I like to level it out at around
1200 rpm.

 

In the recent -10 degrees it takes Pamela about 7 mins to reach operating temperature, though she's running about 15% cooler than in summertime

 

i read in my power tech book in class that your car warms up better under a "slight to moderate load" after been run for a few minutes. what i do is just let the chock at idle at about 1500 then 3 mins or so 2k for a few mins (cold oil is like molasis) then i go down the road NEVER going above 2400.

 

Your motor may generate more heat under a moderate load, but your radiator is far more effecient at removing that heat and cooling things back down if it has ANY forced convection over it when the outdoor temps are low. What this means is that if you have moving air through your radiator or over your motor, it will take longer to warm up, even with a load on it.

BTW, the reason it generates more heat is because it is burning more fuel due to the load. I don't mind reving my motor at 2K rpm under no load when cold. Its the load put on a cold motor that damages it usually. Reving a bit higher under no load also burns more fuel, which equates to more heat generation, meaning faster warmup, and without any stress from loads and no air moving through the radiator to slow down the warmup.

 

If it's cold and the engine needs to warm up, though, the thermostat keeps coolant in the engine until it approaches operating temperatures

 

yea, the thermostat helps that, but i understand what your saying. thats what it said.. and it made sence to me. also, when i just sit in the driveway, it takes about 20 mins to move the bar, but when i start going down the street, it takes maybe 5 mins.

 

i keep mine in a heated/air cond garage.....it dont really take that long, but sometimes when your in a hurry it seems like it takes forever!!! i allways let it warm up to full operating temp (most of the time) befor i drive off in it!

 

Anyone partly cover the radiator in cold weather?

 

The thermostat still has a min flow bypass even when its fully cold, so you are still getting cold water in the motor during warmup, just not as much as full flow. That, coupled with the natural convection off the radiator and motor, and you see that any forced convection increases the warmup time.

 

Its the exact opposite for me. It I drive off, it takes 20 minutes to warm up, and if I let it sit and idle at 2K rpm with the choke on, it takes just over 5 minutes for the choke to pop off.

 

It takes less time if I drive in it, than just sitting around. I usually give it 2 min. though to get the oil in circulation before driving off.

 

How long to warm up for a fuel injected engine? cause i think thats what he has.
