Animals love its sweet taste, so even a spilling a small amount on your garage floor can end up in the dog's stomach pretty quickly. Promptly wipe up any spilled fluid as it is highly toxic. Always wear safety goggles when working on your Alero. Removing the coolant reservoir cap on a warm engine could cause the cap to fly off at a high rate of speed and fluid to spray out of the reservoir. These coolants will typically say 50/50 or pre-mixed on the front of the coolant bottle. Some coolants will come premixed-that is, you don't need to add any water. Mix the coolant / antifreeze with distilled water so that you have a combination of 50% coolant and 50% water. Be sure to check your owners manual to determine the correct type of fluid to add - for Oldsmobiles, it will typically be in a section titled Fluid Capacities in the back of your manual. The video above shows you where the coolant reservoir in your Alero is located and how to add coolant / antifreeze. Make sure to check your engine when it is cold for an accurate reading. Engine coolant / antifreeze circulates through your engine to keep it cool in the summer but won't freeze in the winter. Right now its hate.Adding engine coolant (also known as antifreeze) to your 2000 Oldsmobile Alero is pretty easy. When it does leak, there is lots of info available for you to do it yourself for about 250.00 You will find more info if you search on Pontiac Grand Am 3.4L LIM. I would have to remove a crossover pipe in order to reach the lower bolt that holds the Thermostat in. You will get different opinions, but sometimes a small leak will open after the coolant is flushed. Well I just tried to get at the thermostat, and who the hell designs these things? I was happy with the ease of my brake pad change, but this is just stupid. ( of 2) Average repair cost is 980 at. Average repair cost is 980 at 91,250 miles. There's a bleeder valve on the black metal coolant pipe across the front of the engine IIRC. The 2001 Oldsmobile Alero has 26 problems reported for leaking coolant, intake manifold gasket failure. There's also the possibility of air in the cooling system. I've had cars overheat while the temp gauge read normal - and the gauge was functional. If it is a restriction in the system, that can cause the gauge to read low even if the engine is running warm/hot depending on the temp around the sensor. My coolant reservoir looked good, but looking in the radiator itself you could see a muddy residue. (been awhile since I have seen a vehicle with one of those valves on it)Ĭlogged heater core can often be an indicator that the radiator is also partially clogged.ĭoes revving the engine increase the heat output? That's what I noticed on my '99 Grand Am (3400 V6).Ī reverse flush of the cooling system and heater core helped. I agree, that the problem is most likely a stuck open t-stat, unless this vehicle also has a valve that directs coolant to the heater core. I would assume that the halfway point would be more appropriate.Īnalog indicators traditionally have "normal" (warmed up/operating) position near the straight up 12 o'clock position-this is to allow a quick visual scan of the indicators without having to actually read the #s. Needle just barely goes above the 1/4 mark on the temp gauge. Sounds contradictory, especially in light of the fact he stated his temp gage needle stays down on the low end of the scale, which I assume would be less than normal operating temperature. If you check your coolant, the Dexcool probably looks like mud.īlocked heater core doesn't restrict engine cooling. I may throw a t-stat at it as they are usually inexpensive. Either it's not closing all the way or someone installed one with too low of a temp trigger. What could be another cause? I have considered the heater core, but there does not appear to be any leak, and I would think a blockage would be causing me the opposite effect, and I would be overheating. I don't think there is a head gasket issue, which these cars are known for. There is no oil in the reservoir, and no milkshake in the oil. I have monitored coolant levels ever since I got the car, and I don't think I have lost a drop by looking at the reservoir. I would assume that the halfway point would be more appropriate. I experienced a little of this last year at the tail end of winter, but didn't spend much time on it. When it is finally warm, it doesn't feel as hot as it should be. It takes about 20 miles before it starts to warm the cabin, and put out decent heat. It takes too long for the heat to warm up. It's been a great car, but now that I am facing some colder weather I have a small issue. I bought a 2000 Olds Alero about 9 months ago.
