Default Coolent flush- not planned

Found a great way to flush you coolent..................Go for a nice little drive to clear you mind and the drain plug decides to break and back out.....Luckily, I am prone to looking at my coolent and tranny temps a little bit too much.....I was able to make it home right when she hit about 226 degrees, yes this is normal, but not for my car as the temps are lowered and she sits at about 198 degrees most of the time......This is why I knew there was an issue....i figured it was best to make it to my home and avoid a possible tow.....I guess I lucked out...

I clicked because your subject line made me laugh.

Glad it worked out OK!

Good that you were observant and saw the temps rising. Glad you were able to make it home.

I had a similar scare just last week. The coolant reservoir cracked and I lost enough coolant for water temps to creep up. I just got done swapping the entire cooling system with OEM parts after the dealership said they wanted $540 just to swap in a new reservoir.

If it was just your radiator drain plug, you can get a new one assuming you can get the rest of the plug out of the threads.

That price is crazy. New tanks sell from $70-$85 and used tanks sell on ebay for around $40- $50. It's a 5 minute job after you siphon out most of the coolant. Remove 2 bolts up top, loosen the one underneath, unclamp 3 hoses then reverse the process. Then add the removed coolant plus a little more. Job complete.

It takes a little longer if you pop the hose off the reservoir thinking you can cover the outlets with your fingers while you remove the tank and then spend the next hour cleaning coolant off the garage floor.

The whole cooling system replacement took about 6 hours total with some extra hands from a couple of friends.

If if makes you feel any better tabbruzz, I had an unplanned oil change after sending two rods through my block and oil pan.

Nice job on keep an eye on your gauges. It's super easy to get complacent.

No offense, but I strongly prefer coolant leaks to block unauthorized block ventilation.

Lost coolant on a CTS-V I was driving about 18 months ago. On the highway and the car went into limp mode. ALL the supercharger fittings had become brittle and crumbled in your hand. Nice work GM. If this car was a manual I would still have it.
