![]() ONLY 1 lb 1 oz for a total of 24 lbs 10 oz. Now I remove the passenger side wiper arm and replace the drivers side 20" blade with a 24" one, just like my drag car, and remove the "oh hell" passenger side handle. ONLY 1 lb 1 oz for a total of 23 lbs 9 oz. Next was reducing # of excess keys on chain, screw driver, a couple of half empty water bottles, and lots of loose change. Out next were a book, floor trim beside both front seats, trim around handbrake,metal bracket on left frt side of console. ONLY 2 lb 9 oz for a total of 18 lbs 3 oz. ONLY 4 lbs 4 oz more for a total of 15 lbs 10 oz. Next removed was the drivers junk floor mat, extra ink pens, interior trim from both side mirrors, cigarette lighter, and ash tray. I took out a few tools, frt lisc brkt,spare tire clamp, spare fiberboard cover, spare tire rubber sound deadoner, rear shock tower covers, misc screws, and all rear compartment trim. The car was 1800 lbs as it sat with a full tank of fuel, some extra toys and clothes for the kid and the baby seat. ![]() I also use this car with my 2 year old in his car seat so the back seat stayed entirely. ![]() Weight hurts performance and FE on everything so this last weekend I did what I set about to do. It got 46 mpg for the 195+ mile trip home and after putting on new plug wires, cap, and rotor it got 53.6 mpg at about 5 mph less. If anyone has a different configuration than what is listed here, feel free to send either freegeo or myself a PM with a picture of your sensor(s)/switch and specify your year and engine so we can update or correct this post as needed.I bought my Geo Metro a week ago last wednesday for double the FE of my delivery vehicle (I sell & deliver 79-08 Mustang rims) and have put nearly 1000 miles on it already. These sensors also have a separate signal directly from the sensor to the gauge.įreegeo and I put these together using Factory Service manuals, GM expanded parts diagrams, and whenever possible, inspecting the actual vehicles and taking pictures of the various years/configurations. When OBD II systems began in 96, there was now only a single sensor that sends information to the PCM, which then uses it to control fuel scheduling, AC shutoff, and control of the radiator fan relay. On the 1.3L this sensor is in the thermostat housing next to the Engine Coolant Temperature sensor for the ECM. On the 1.0L the coolant temperature sending unit for the gauge is on the lower right side of the intake manifold. When discussing a pre-95 sensor/switch, the words "Engine Coolant Temperature sensor" or "ECT" do not clearly indicate which sensor is being discussed as there are four separate sensors - two on the thermostat housing and two on the throttle body, all with very similar sounding names (except the radiator fan thermostat switch).ĩ5 was a "transition" year in which the sensor on the thermostat housing now fed the ECM (which controlled the radiator fan relay and AC shutoff during an overheat), but there was still a separate sensor for the gauge. Auto parts retailers such as Auto Zone, Rock Auto, etc seem to list more generic names and may even show different sensors under the same "name," in which case having the correct sensor in your hand in order to match up the actual picture can be very helpful. ![]() GM databases seem to be the only consistently specific with respect to listing what the sensor does, although some parts diagrams still show configurations from previous years that don't show up in the individual listings/descriptions. Also, the configurations and number of sensors used to perform the same engine functions based on engine coolant temperature changed over the model years. Discussing or attempting to order any sensor or switch related to engine coolant temp can be frustrating, in part because the terminology can be "too" similar" sounding and create confusion. ![]()
