Antifreeze/Coolant leak

[HUMMERADDICT]

Filled my Antifreeze/coolant last week cause I noticed it was a little less than half full. Go to check on it again this afternoon and it is empty. Seems like I must have a leak. I would venture a guess that it is not normal to go through that much in one week?

 

[HUMMERADDICT]

I should also mention I have a faint burning smell coming from my exhaust and engine compartment. Would you folks recommend heading to work late tomorrow to go to the GM service dept?

Look at the top header where it meets up with the radiator support. See if it is leaking there.

If you can't find any signs of leakage there check your transmission fluid level

I went out and looked but its hard to tell in the dark with only a flashlight and ice and snow all over my truck. I do see wet spots.

Forgive my ignorance but can you explain how my transmission fluid is affected by my antifreeze?

I would bet that you have a crack on the top of your radiator. My 07' did it when I had about 60,000 miles on it. There have been hundreds that had the top of their radiator crack. Take it to the dealer and be sure to contact GM if that is the problem. I forked out 900 bucks to fix it and a lot of people are getting GM to cover a majority of it if not all. Just don't take no for an answer.

Some have had problems with the transmission cooler that is integrated with the radiator cracking which will allow coolant in to the transmission. Check the trans to be sure it doesn't have coolant in it.

I've had the crack F5 mentioned. If you are out of the bumper-bumper warranty contact GM. I was a ways out and payed $200 for the repair.

YUP, Cracked Radiator. Another one. At only about 47,000-48,000 miles. Waiting for the callback from GM to see if they'll help with the cost. Dealer quoted me $630 for parts and labor. Hopefully GM will pay atleast half. When I called the dealer I purchased the H3 from after I went to my local dealer they told me they had fixed numerous H3's with the same issue. Mostly 07's though.

If this is on your 08, go for a complete replacement at GM's cost. They did for me. When mine was replaced under warranty, I had about 49-50K, and technically went off the 4 year warranty by about six months and GM covered the complete costs. Dealer was also a big help in getting it covered.

Yeah, same here. My B2B expired on years about 4 months ago, but I told them i'm only at 47,000 miles. Still waiting for the call.

Let them know, that you know, there was a problem with this top header leaking at the seam. Very common on 07, not too common on 08 at low miles. But it can happen.

I replaced mine and did the work myself, radiator was about $250.

Still waiting for a callback.

Oh, also, some smoke pouring out of my grill.
Keeping antifreeze full until repair is made.

Dealer wouldn't help me. I got the AC delco radiator on eBay for about $150. Changed it myself in an hour.

 

[HUMMERADDICT]

Is it normal for GM to make people wait a week or more for an answer. I'm assuming they are biding their time to think of a nice way to tell me to **** off.

 

[jakesz28]

Nope they made me wait a week and a half. Several phone calls and I said f--k it. Ordered the radiator because I wanted to drive it. When they called that time my wife told them to forget about it. I already fixed it.

Maybe they're hoping I do the same.

 

[HUMMERADDICT]

Just got a call from the dealership working with GM on my case. He said he was tired of waiting for GM to return phone calls and just ordered the part and is gonna make GM eat it. Said radiator should arrive to him on Wednesday, which would be perfect cause i'm off.

 

[poncho1965]

Good deal! :thumbs:

 

[HUMMERADDICT]

pffft. Just got call from GM and they explained to me that they are still working on my case. *face palm*

Well, dealer already told me they are fixing it and charging it to GM. Hopefully I didn't get the dealer in trouble with GM. I let the woman on phone "have it." I told her its BS to make someone wait this long for an answer, even if the answer would be no. Atleast i'd know. Told her i'm PO'ed with GM customer service center and would most likely never be buying a new GM product again. Seriously, does it take almost three weeks to come up with an answer for this? Ever bitch someone out on the phone then kinda feel a little bad for it after? LOL!

Oh, dropping my truck off tonight to have it repaired first thing in the morning.

As I was preparing for my 6hr trip thru the blizzard yesterday I was checking my fluids before I left. I popped the hood and I see antifreeze on the inside of the hood. My reservoir was empty and it looks as if I have a hairline crack in the top of my radiator. Mine has 69,000. So I filled the reservoir up to the cold line. I made the trip in the blizzard fine. It took 7 1/2 hrs for a 6 hr drive. Blowing snow the whole drive except the last half hour. But the fluid held up fine. Seems like its only a lil hairline crack, but its under warranty so as soon as I get back home, she is going into Cadillac of Novi for some TLC.:thumbs:

Did you buy an extended B2B?

Don't feel bad about pissing off GM customer service. Nothing you said is any surprise to her....she hears it every day...all day...from everyone that calls! GM pays her salary to listen to customers bitch & complain...and then calm them down. Customer Service has nothing to do with repairing cars...improving the product...or customer satisfaction. Instead its merely a way to maximize profits. They have found out that it is far cheaper to pay this woman to listen to your rant...than it is to do the right thing. I'll admit...her job totally sucks and its gotta be tough to go to work everyday to defend a company that is so utterly un-defendable.

Forget the "I'll never buy a new GM product again" trick. It won't work. They don't care about US customers. We are demanding and difficult to deal with...plus we have a legal system to protect the buying public from such shady business practices. As of 2012...GM has digressed to the point that its simply easier and cheaper to go somewhere else to make money. That place is China. The real future of GM is the Asian market, and that's where they are focusing all of their energy.

Like an old girlfriend...we (the US consumer) are just a cozy bed and a roof over GM's head. Our long-time lover has already filed for divorce and he now keeps a toothbrush and an over-night bag in China. In the next few years, we will cling to him and beg him to stay...insisting we can work things out...remembering when our relationship was solid and true. He continues to say he loves us but...he's really just hanging around for the paycheck (bail-out). Eventually he will fess-up and admit that he loves someone else, and he will leave for good. Its just as well...probably best for both of us that he moves on.

Its better to have loved and lost....than to never have loved at all. Sigh.

Great post. It really upsets me that GM is like this. Hell, 4 out of the 5 cars i've owned had GM's fingerprints on them. Back in the day I swore i'd only buy GM products. Well, that has passed. Not only did I lose Hummer, not only am I fed up with GM, not only did Isuzu leave the US, but now I also lost Suzuki whom I liked very much. Every damn car manufacturer I touch seems to turn bad.
