Years ago I used to put in a higher temp thermostat in vehicles so it would warm up faster in the winter. Is this still possible? Does it effect the computer reading in anyway? How much work to change the thermostat in a 07 F150?

Thanks!

 

You have a very sophisticated computer controlled engine and changing the stat will make your fuel mileage go down with no other value added.

 

Thanks for the info...

 

A hotter T-stat will taker longer to get up to temp. But will put out hotter air from the heater. And what he said. I'll bet your '07 warms up way faster than anything you had years ago. I know mine does.

 

Don't understand how a higher temp thermostat would warm things up quicker.

Suggest a better approach, if you're so inclined, would be to block off a portion of the radiator airflow - 1/3 to 1/2 of the area - kind of like the big semi's do. Have to watch your coolant temperatures when doing this - certainly don't want to go the other way and overheat.

Also, when blocking, need to know if it's a top-down flow, or a cross-flow radiator, so to know which way to block. The intent is to reduce the large temperature swings in coolant temperature in efforts to keep things a bit more constant.

 

Changing out the thermostat for a higher or more popular lower temp is a waste. These rolling computers don't like lower ones because they'll operate closed loop (rich) and get **** poor mileage. In hinesight, looking back when my t-stat failed (fully opened), mileage went down and it never got up to operating temp ever, staying closed loop. If you want the truck to warm up quicker, use the block heater, get some e-fans and/ or get a remote start. The e-fans do allow quick warm ups.

 

yeah i put a 160 in during the summer, worked out great, but then it started getting cold and wouldnt get above 170, used a LOT of gas and ran bad, put the 180 back in and it runs much better, about 2 more mpg...

 

The stock stat is already a 195 - you don't even want a hotter one in there.
