99 Pontiac Grand Prix 3.8 v6 Error code 118-

99 Pontiac Grand Prix 3.8 V6 171,000 miles:Error code 118- Coolant temperature switch. I bought one at parts store,how and where on the vehicle do I replace it? I'm hoping it might be cheap fix to the intermittent starting problems I'm having

I also added some EFI cleaner to gas tank

I also bought a fuel filter that I'm told should be replaced on fuel line somewhere near rear of vehicle but not in fuel pump/gas tank
Any comments on any or all of these three possible solutions to error code 118 as mentioned above

99 pontiac grand prix smells hot after driving 30 minutes


If the temperature gauge looks good (under 3/4) its all good. If not, then there is a problem. If it smells hot inside, like moist and humid you will need to replace the ac filter, that can be located under the hood, close to the water resevoir, you will have to pull the ruber type gasket that is on the edge of the hood/wiper cover.

Fan wont work fuses are fine coolant level was low i filled it up


I suspect you have a bad fan relay or temperature sensor. Here's a link to a page where you can see what these parts look like. The fan relay is usually located in the engine compartment inside a plastic box with a removable lid. It just plugs in and out. The temperature sensor will screw into your engine block and have a cable connected to it. Your owner's manual may give you their exact locations. http://www.diypartscatalog.com/ShopByVehicle.epc?q=2004-PONTIAC-Grand--Prix-V6--31ci--3.8l--F/i--Vin---Belts/hoses/cooling&yearid=2004%40%402004&makeid=67%40%40PONTIAC%40%40B&modelid=13463%40%40GRAND+PRIX&engineid=30226%40%40V6%2D231ci+3%2E8L+F%2FI+Vin+2%40%4030226&catid=2%40%40Belts%2FHoses%2FCooling&subcatid=36@@Sensors%2C+Switches+and+Relays&mode=PA

Is there a special way to add coolant to the Grand PRix


I assume it's a V6, I know from working on Fords and when we would refill the radiator on a V6, we would take the upper hose loose from the radiator and back fill it that way. Hope this helps

Srs airbag light is on on my 99 pontiac grand prix


If the seat belt light comes on intermittently with the belt buckled, it may have a bad switch in the buckle or a loose connection @ the switch. This may also set a diagnostic trouble code in the srs control module & keep the srs airbag light on.

Engine overheats on Pontiac 2002 GP


Check the catalytic converter. If it is clogged, it will reduce your your power and increase the temp of the car, especially on steep inclines.
