Im also having the whole overheating problem thing, as is everyone else on the fourm. but with the 0% oil life all you simply do, is while you press the select button when scrolling through the options, engine temp, rpm, mpg, etc.... simply chose the option you want and then hold the button till it resets. that can be done for the average mile per gallon and the average mile per hour option. wish i was more help on the overheating, but atleast that got figured out. good luck. it seems we all need it. cursed love for cadillac.

99 Firebird still overheating after repairs and antifreeze


overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.

White smoke coming from exhaust


White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area.

If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.


How did antifreeze get in the oil or cylinder in the first place? The engine probably overheated and a head gasket failed due to excessive heat, thus allowing antifreeze to enter the cylinder (Where it is not meant to be).

Hope helps with this (remember rated this help) Good luck..

Electric cooling fans will work.


The fans are actuated by coolant temp in the radiator. It is possible to have overheated coolant in the radiator, causing the steam, and your engine not overheating...the temp sensor for your engine is reflecting the engine temp, not the temp of the coolant in the radiator. You problem could be a bad temp sensor at the radiator...not allowing the fans to come on. Good Luck! I hope you find this to be very helpful!

HAve a 1996 Ford explorer v-8 that is overheating,


With cool engine... open radiator cap and look inside radiator. Do you see lots of sediment and calcium growth on radiater tubes? If yes, a coring may be needed. If only slightly bad, a radiator flush may be needed... then refill with 50 percent antifreeze.

Good thermostat, cleaned cooling system, non-leaking water pump, good water flow via water pump... nothing else left (unless you put the thermostate in backwards)..

Let us know
