3.0's take forever to warm up?

why do these 3.0 motors take a long time to warm up?

my buddy also has a 95 arrowstar with the same 3.0 and he says his takes forever also?

My temp gage comes off the peg in the first mile, and warm air comes out of the face vents.

Fully warmed up by the time I hit the 3 or 4 mile mark.

Have you replaced the thermostat?

FWIW, my fan clutch disengages before I hit the end of my street, but it is considerably warmer here in NE NC than Buffalo, eh?.

I hate how mine takes forever. I get up at 4:30 everyday to go to work and sometimes I have to wear 3 layers just to warm up before I get there. Even for southern california it can get pretty cold in the mornings.

Why would the fan effect it if the thermostat is working? If it is properly closed, the water in the engine is not affected by the fan until the engine warms and the thermostat opens. Also if electric fan, it should not be running if the engine is cold. Not saying anyone is wrong, just don't understand.

if the fan clutch is not functioning properly the engine will never get to proper operating temp. (195)
most of the time the clutch is seized up or freewheels.

the fan clutch is thermostaticly controlled, it only moves air when the radiator gets hot, if the clutch is frozen the coolant in the radiator can never get to operating temp due to to much air being mooved across the fins.


sounds to me like a thermostat is where i would start

The coolant thermostat is closed until the coolant hits about 190F, so almost no coolant is moving between the block and the radiator during warmup. Why does it matter what the fan, electric or mechanical, is doing during that time?

are people really that dumb?????? have you ever cranked your car with the hood up when its cold???? there is a considerable amount of airflow over the engine during warm up with the mech. fan!!! with the efan there is no air flow to cool the motor during warm up. if its 35 out then your mech. fan is blowing 35 degree air over your engine slowing down the warm up process quit a bit. like i said before my warm up time was CUT IN HALF with the efan.

I may be dumb but I do know that the air flowing around the outside of the engine assembly only accounts for a tiny fraction of the cooling of an engine. I am not stupid enough to believe that your engine warms up twice as fast with an efan in place of a mechanical fan equipped with a clutch that all but disengages within the first minute after startup.

I go from 1200 ft elevation to 1450 ft elevation in the first 1/2 mile out of my driveway. No problems warming up here.

I hear ya!!

No problems with mine.

I'm with the others that said to check your T-stat. Maybe you don't have the right temp one in there.

I'll I know is after hearing all the nightmares and horror stories about those efans.......I wouldn't put on in my truck if someone else paid for it and installed it. My stocker works just fine with no problems.

I like to stick with "if it ain't broken, why replace it".

*Some of you need to have a coffee before posting too....or maybe step back and count to 10.....yikes!!

It's an electrical fan that takes place of the mechanical fan on the motor.
