Manage Your Heat!!!!!

MANAGE YOUR HEAT GEO METRO FANS!!!


The best thing you can do for the Geo Metro is install a switch to the fan. The Geo Metro has heat problems when sitting in traffic or idling in summer. The temperature level programmed in the ECM that switches on the fan is so high it damages the engine over time, so override the computer by installing a switch and using it when in traffic or even around town in summertime. Just find a power source and run it through the switch to the fan coupler.
It is important that you are vigilant with the switch. If you are a start and go type of driver who would be apt to neglect the switch I would recommend the following two as well:


Run the heater in the summer. If you put it on defrost with the windows rolled down the heat goes out the corner of the window. You won't even know it is on. This is crucial for managing heat, important especially at freeway speeds which could damage the fan if on, since it spins the opposite way



180 degree thermostat
Install a 180 degree thermostat. It doesn't affect performance and gives an additional measure of protection.

Umm, i'd like to know how 15 extra degrees can affect the longevity of an aluminum motor. Whoever gave you this information is smokin something silly. The only thing that damages a suzuki motor over time is lack of regular fluid checks and changes, and abuse.

engines will actually show more wear if they don't warm up enough.

Wouldn't you be able to notice the temp gauge going up?Mine stays the same throughout the summer.Nope I won't do that trick.

'89-'91 had the half-circle sensitive guages, where you can notice an increase in heat when in traffic, at a stop light, etc.
'92-'94 and all convertible models had the quarter circle temperature guage that moved little or not at all at changes in the temperature.
You could have been frying your engine and you wouldn't have even known it.

Did you happen to ever notice when a engine overheats that you can smell antifreeze?

Engines don't "fry" per say. They heat up to the point where the engine head warps, or the headgasket tears. If you literally melt an engine block, you did something WAY wrong. No metal in an engine will get harm from anything less than 300 degrees operating temperature. An engine will warp the head, or blow a headgasket at about 250-280, and cease to run. Sometimes cracking the head. Blocks cracking due to heat is rare, but happens. No engine is gonna show wear from an operating temp of 200-215 degrees. The combustion chamber temperature is WAY hotter than the rest of the engine. It's constantly sitting at 1000+ degrees. The cylinder walls absorb some of this heat and pass it to the coolant. More is absorbed by the oil spray on the bottom of the piston, oil in the head, and the rest is passed through the exhaust. I bet you also stand by those "electric superchargers" and think your honda got 40hp from it Go away.. n00b
