V6 Overheating Issues
I'm trying to help out a friend of mine and I don't really know anything about these V6 engines. The car is a 2010, V6, with around 175k miles. He's had it for a few months, and it just randomly started overheating this past week. He said it wasn't leaking from anywhere.
We are going to do a coolant flush and thermostat replacement. I watched some youtube video's and read some posts. I'm going to try and do it without removing the intake. Thermostat looks like it's in a lovely location on these cars We played with it a little the other day, and the reservoir was topped off, but when I pulled the coolant cap the engine's coolant was low to the point were it took about 3 maybe 4 quarts. So I topped it off and it overheated again still. Is there a reason why the engine isn't pulling coolant from the reservoir? I ensured the hose was free of debris. Is there anything else I should do or check while tearing into it? What's weird is the engine coolant that was in block looked alot like the green mix, when I know the Dex-cool stuff is supposed to be red. So that's the main reason we want to flush it all out. I also want to do a good burping to ensure no air is trapped. Anything else I should be looking for or doing? Any good writeups or tips about flushing & burping? |

It don’t come easy.

As far as pulling from the reservoir, it could be the radiator cap, itself.

I had this happen to me and I had a hard time figuring it out. It was the water pump, the propeller is pressed on to the shaft and had just fallen off inside the block, no sound no nothing. you can take off the belt and see how easy it is to turn the water pump pully.

I had temp spikes, it ended up just being a worn out Radiator Cap. Probably the easiest and cheapest place to start. Around 15 for an OEM cap.

Have them make sure there is no air in the system. I had similar issues with mine after a radiator flush & the guys at the dealership failed to get all the air out of the system. A friend of mine worked on it most of a day at a car show to run the engine, squeeze on the hose, watch tons of bubbles come up, add more coolant, let it rest a while & repeat several times. Then it was fine.
