Wife overheated the 2005. . .

[79jasper]

fixed trans fluid leaks from the loose fittings (dumbasses at the factory didn't tighten the fittings)

Anymore, I check anything that comes pre-assembled.
I have had plugs come put of brand new waterpumps. Since then, I check everything.

Speaking of, I find it cheaper to get the coolant concentrate and a few gallons of distilled water from WalMart than to buy the pre-mixed bottles.

This is what I do, too, but almost never have to add much water. Consider that after the flush there will be a considerable amount of plain water left in the block unless you're pulling the block drains. Using concentrate will help get the mixture to 50/50. If you use pre-diluted you may never get to the desired mixture.

Change the OIL

My old truck, I changed the radiator. The new version, same as the old one, the manufacturer deleted the drain plug.

Avoid a drain plug IMO.

Odds are you will be ok. Just last month my daughter was using my 04 YukonXL and while driving (in town just coming off the freeway) massive white smoke started pouring out from the hood. She pulled over at a gas station which just happen to be right there and it would not start (due to overheat). It was late at night, she called some friends, they came over and pushed it into a parking space and she left it there for me to deal with in the morning. When I got there and popped the hood, the driver side heater core hose had snapped off (its that T shaped white plastic connector) at the hose connect - dumping the entire coolant on to the engine. I went and picked up a 5/8" hose splice, cut both hoses and spliced them together (bypassing the heater) and refilled it with a ton of fluid (it was completely empty). Ran like a champ - the sensor worked as intended and protected the engine. Once I got it home, pulled the codes, cleared it and my patch was working well. Since then I have replaced everything that is hose or plastic in cooling system so we don't have that again - all that stuff is 16 years old and getting brittle. I did a compression test - no issues - not bad for this original engine with over 220k miles. Short story - as long as the computer did its job and the temp sensor did its job shutting the engine down AND you have been keeping clean synth oil in it - you should be good.

One thing I have seen on this forum is a recommendation to obtain stainless steel replacements for those plastic (nylon?) tees. I have a 2005 Yukon with 189K miles, so I am probably running on borrowed time, but I will get the stainless tees when the time comes.

I am surprised nobody makes a cast aluminum replacement that is identical to the plastic ones....

Yeah, I’m not a fan of the 6-8 clamps necessary for the Gruven T’s. In reality, for me, a set of the OEM plastic ones is fine considering they last at least 10 years. Just like other parts, they just need to be replaced as a maintenance item. IMO the Gruven parts probably wouldn’t have been invented if Dorman didn’t make cheap knock-offs that only last a short time, which caused people to suffer multiple failures. There’s very few Dorman parts I would buy, and these aren’t one of them.

How about machined?

Can’t use quick connects with that, can you? Looks like clamps are needed.

Clamps, for sure. But for only $10 more than the plastic ones, I'll bite.

Another update. I've heat cycled it three times now. Lost some coolant level after the first one, but I expected that, happens every time you reload the cooling system in my experience. And I did lose about the amount I expected. The second two times, I didn't lose any level. So far so good. I do need to replace those t fittings though. They are not leaking, but we don't need another disaster.

Edit: and yes, it gets to normal temperature, and stays steady at that temperature. Just below 210 on the gauge, just like before all of this happened.

If you get the plastic T’s make sure they’re AC Delco parts and not Dorman or any other aftermarket plastic ones.

It took me 3 top-offs to get my coolant level stable at the proper level mark on the reservoir. Since then, the level has not moved.

Yeah wives right? I think we could all use a chuckle these days and this reminds me of an incident. Back in maybe 1980 my boss was found sitting at his desk just shaking his head at what his wife just told him. Apparently, she had their new Porsche out shopping and it overheated in traffic. So she thought she'd pull into a gas station and cool the motor off with a water hose. Crack! Gotta love 'em.

OK...now where's MY coolant going??? Have to add about 3/8" to the reservoir every few weeks. Dealer finds nothing. Garage #1 replaces radiator cap and hose clamps. Garage #2 does pressure test = OK. Garage #3 does dye test and another pressure test = no leaks. Oil always looks perfectly good. No white smoke front or back. So after 4 garages...I still keep a gallon of antifreeze in the back seat !!!!!

Check your water pump. It may be on its way out. The weep hole starts losing coolant about the time the pump is going out.

Wife and truck/car overheating stories........

Years ago, before cell phones, my girl friend (to become my wife) was returning home on a remote road in the late evening in the winter after work in her '67 Buick Special with the V6 motor, and her temperature light came on. It was extremely cold, and she made the decision to try to limp home, rather than stop in the middle of a cold winter night on a remote road. Naturally, she drove until the motor fully overheated, seized and stopped. Eventually, a cop came by, stopped, and radioed into the station to call me at home.

I could not really blame her for her decision, as I could fully understand how she felt exposed in this situation. But, since the result of her decision was going to cost me a lot of time and work in rebuilding her motor, I felt that it was appropriate for her to participate in the rebuild. Amazing enough, that V6 motor held up very well, under the seizure, and the only true damages were 2 pistons needed to be replaced. Further, there was minimal cylinder wall scoring in any of the cylinders.

So, the 4 remaining good pistons needed new rings, but prior to installing the new rings, the carbon deposits within the ring channels on the pistons needed to be removed. As such, I gave her the pieces of broken rings from the damaged pistons, and I had her scrape out all of the carbon deposits in the 4 pistons with the pieces of broken rings. This carbon scraping job took several hours to complete, and I can assure you that she was NOT happy about the work. But, like a real trooper, she persevered, and completed the job. In addition, she was present and served as my assistant, throughout the entire motor rebuild project.

Result of the experience: Whenever something goes wrong with her car, or even if she thinks that something might be about to go wrong with her car, she immediately stops the car, and I receive a phone call from her.

Yeah, during that motor rebuild project, I knew that I had a keeper in her. Why she decided to keep me, still remains a mystery to this day.
