what I did was cut the 14 wire at the IRCM FAN RUNS LOW SPEED NOW.................STILL RAN HOT SO I TOOK OUT THEMOSTAT REMOVED COOPER PLUG PUT A FLAT WASHER IN WITH 9/16 HOLE ...........................RUNS BETWEEN 130-140 ALL THE TIME...................FAST FREDDIE ::LJGriggs said:The thermostat will open quicker, but once it has fully opened, you won't see any difference in volume of flow. There may be some benefit from the thermostat remaining fully open for a longer duration (due to the lower temp "trigger"). The greatest benefit comes from using the lower temp thermostat in conjunction with an adjustable cool-fan switch or a manual overide fan switch........
Duffy Floyd said:For the guy who pulled his thermo....bad idea. The EEC does not come out of open loop until you get above a set temp somewhere around 195 so now you are likely contaminating your oil with the unburnt fuel you are washing the cylinders down with.
Also for the guy looking at a lower temp thermostat......don't run your car in cold temps or you will be in the same condition as outlined above. BTDT on my 89. Dropped 4 MPG in the winter and the oil came out like water from the gas in it last spring.
The air dam is GM P/N #22635885. It fits the ’92-‘98 Pontiac Grand Am and it costs about $16.50. It's 3 inches high and leaves about 4 inches of ground clearance when installed on my stock height '93 SC.
There are 4 holes in the flange of the air dam; let's call them #1, #2, #3 and #4. Drill a 5/16 hole in the flange midway between #2 hole and #3 hole. Then using a rat-tail file elongate #2 hole about 1/4 inch toward #1 hole and elongate #3 hole about 1/4 inch toward #4 hole. Using 3/4 inch long 1/2-20 screws, washers and Nylock nuts in holes #2, #3 and the new center hole, secure the air dam to the bottom of your front bumper cover using existing holes in the cover. Drill two new holes in the bumper cover coinciding with #1 hole and #4 hole in the air dam. Again using 1/4 inch long 1/2-20 screws, washers and Nylock nuts secure the ends of the air dam to the bumper cover. (Vernon C. originally)
