An anti-freeze leak can cause the temp sensor to record high engine temperatures in a 2001 Chevrolet Malibu. If you ignore a small coolant leak long enough, you will run out of coolant, which leads to an overheated engine and other serious, but highly avoidable, problems. This video shows you where the coolant reservoir, hoses and connections on your 2001 Malibu Base are located and the steps needed to fix minor leaks.Ī few things to note about coolant is that it is sweet tasting and highly toxic, so it can end up in the dog's stomach pretty quickly. Replacing the intake manifold gasket should correct these leaks. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Otherwise, your Malibu may have a radiator leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Check all the heater hose first, and try to find out. Its common that the 3.4 V6 has intake manifold gasket go bad and leak. However, a coolant leak (aka an antifreeze leak) is most likely to occur where the hoses connect to the engine or radiator. Where is the fluid leaking from, if there is white smoke coming from the tail pipe then good chance is that the head gasket is gone and pull the dip stick out to see if there is antifreeze mixxing with the engine oil. Coolant / antifreeze can leak from the reservoir, radiator or any hose, in 2001 Malibu with the 3.1 liter engine. Engine coolant (which is also called antifreeze or anti-freeze) moves through the inside of your Malibu engine and keeps it from overheating. Leaking coolant / antifreeze is one of the more common types of leaking fluid from Malibu engines.
#Coolant leaking from water pump on a gm 3.1 v6 how to#
Someone mentioned a freeze plug but we are getting conflicting information on if our car has a freeze plug (expansion plug) and how to replace it.Follow the steps in this video to see how to fix minor coolant (antifreeze) leaks in your 2001 Chevrolet Malibu. Let us know if you have success locating the leak, or if you have any other questions. There doesn't appear to be a hose in the back of the engine. You add the dye to the coolant when the engine is cool, run the engine and with the glasses and the light you should be able to spot the source of the leak. We took off the water pump and it looks brand new. Husband has the repair book but he is at a loss. Husband looked and it's coming from the back of the engine. I checked the car this morning and had a puddle under the car. Just make sure you have a good set of Torx sockets.
Had to replace the gasket twice in three years. On the way home, every stop I made, the temperature climbed. looks like the gasket between the timing cover and block or water pump to timing cover. I was at work 14 hours and did not see a puddle under my car. I put in the 50/50 mixture in between the max fill and min fill line. The upper and lower radiator hoses were replaced a few months ago and the water pump is 2 years old. An hour later, I checked the engine coolant overflow and it was dry.
I got to work and smelled what I thought was coolant burning. Once I turned off the heater, the temperature went down. I noticed yesterday my coolant temperature was climbing while the car was warming in the driveway. Hi, I'm new to the site and a little frazzled.
