To make a long story short...

I have a 2008 GXP with 43,301 miles. 3 weeks ago before I went out of town on business, I was drying for a late night run for ice cream with my sweety and the GXP was overheating! Basically, we had to let it cool and added the appropriate antifreeze from a local shop and would drive until overheating again, then pull over, let the fans run until we limped it home after about 4-6 times.

The temperature was over 255-260 degrees. I noted pink foaming in the radiator. During the escapade, I added a lot of fluid, but then it didn't seem to take any more and was full. Further, there was evidence of some overheating and the pink on the inner wheel well. I decided to run the heat on high and feel the air temp. It was cold, which led me to initially think it was the thermostat not circulating.

Once home, I let it sit and made arrangements for a previous Pontaic specialist dealership to tow it to them and check it out over the weekend.

I finally heard back from them this afternoon and basically they are stating the radiator failed. The transmission cooler is integral to the radiator and it caused coolant and radiator fluid to mix! They need to flush the radiator system and hoses and transmission replace the radiator. Likewise, they need to pull the trans pan and clean that up and inspect and replace the trans filter. The total cost is $1,559.54!!

My questions are thus:

Does this seem feasible?
Does the cost seem appropriate?

The cost breakdown is as follows:

$442.14 parts (trans filter - 57.73, ATF - 4.16, Radiator - $344.25, Coolant - $18.00)
$467.90 sublet (With BG Flush Kit - 134.95, Complete Trans Flush - 164.95, Towing - $168.00)
$568.40 Labor (Inspect and Diag Overheat - 1hr, Trans Fluid - 2hr, Replace Trans Filter - .80, Replace Radiator - 2hr) - 5.80hr @ 98.00/hr
Tax - 56.10
Shop Supplies - 25.00

Since this is a failure of radiator, they are saying not under warranty and soo I would eat the entire amount. The dealership is Red Holman in Michigan.

Let me know your thoughts. I'm crushed and with the cost being 10% of the cost of the vehicle and I've had issues in the past, I'm ready to say take the damn thing! A very upset owner. :(

B/S it appears you've been had.

The water pump has probably been seeping fluid or some other leak and these cars are known for trapping air causing an overheat condition. That is why there is now a TSB on adding check valves to prevent air from getting trapped.


Also, since the car is a pressurized system, you should never open the reservoir cap until the car has cooled down.

The coolant will boil and appear foaming if the temp gets too hot.

Adding fluid won’t solve the air void problems. The reservoir is required to be lifted 10 to 14 inches above the engine when bleeding out air.

See DDM Works video on bleeding the coolant

I'm a little confused cause up above I highlighted what you posted, don't you mean coolant and transmission fluid mixing??

I am also surprised to hear this. I didn't know our kappas extended our radiator to the transmission? Do you have an automatic? Also intrigues me how the radiator in the front of the car covers the tranny in the center of the car?? I also wonder if it is the same with the NA's.. Once I (we) see more clearly on these points perhaps an honest answer can be given. I haven't ever heard of tranny fluid mixing with coolant, oil? yes, tranny fluid, no.. this is a first for me to see..:huh: I'm looking forward to comments from members here..

Yes, the transmission oil cooler (for auto) is integral with the radiator and if a leak between the 2 occurs, trans. oil and coolant will mix, not a good thing. As to the prices,.......dealer.

Yes, it is an AUTOMATIC. I've been told and read the transmission cooler and radiator are integral and failed and soo the trans fluid ATF and coolant mixed.

As an update, they dropped the pan to ensure I didn't ride it too long and/or the trans/clutches, etc. got damaged. They acknowledged no further damage and trans is fine, soo it will replacing the radiator, and flusing the coolant and fluid a few times, and replacing the trans filter, etc.

I yelled about the price of everything and parts at MSRP and worst case and they weren't doing anything for me. Finally, they said they'd use a coupon/discount and drop the total cost from ~$1559 to $1300 (20% drop). I agreed to this so far and are awaiting the radiator to come in (about 3 days) and finalize.

On a last note, I requested them to try and get GM engaged for the radiator failing. Can anyone confirm the radiator warranty? I have about 43,300 miles, but purchased it from the dealership in OH with 19k, soo I've only put 20k miles on it and am paying 10% of the current cost of the vehicle! When I authorized the trans pan drop, I did the radiator also because they said they could not conclude if it was the original radiator. I agreed. Upon follow up, they are saying it is not a GM radiator! I told them it was never in an accident to my knowledge and I have no idea why it would be anything other than a GM radiator. I told them when I pick it up, I want the original radiator.

Stay tuned and let me know if you have any further input. Thanks for your support.

Are you within 5 yrs of new? Cos if so, your 5/100k drivetrain warranty should cover this (provided, of course, it IS a GM radiator).

That whole deal will have to ride on the date it was put into service, and that date that dealer should provide.. IMO, if its under 5 years, he's home free and should be covered under warranty.. an 08 purchased by the original owner when??:huh: And who in their right mind would put a non oem rad into his car while under warranty... I smell something is not right..

Ok guys, piked it up today. The total was ~$1,250.00.

I will have to check the exact dates, but yes, it should be within 5 yr/100k. I will check my original paperwork from the dealership and see.

Yes, one of the issues is they are saying it is NOT a "GM" radiator! Now, I purchased it new/used from a dealership in OH with about 19k miles. It has about 43k now (2.5 yrs later). I'm not sure what happened before I had it, but it was never crashed and I never replaced it.

I told them I want the original parts. They said they had to flush it literally like 4 or more times to get all of the pink jelly coolant/trans fluid mixture. They were very concerned about thedamage to the seals and hoses and what not from th trans fluid and frankly told me they would get rid of it!!! :O

There is one tag on the raditor. it says the following:
Cust #12242007.003
Prod #ACM7-00785
Part #C081-012-0001
MADE IN U.S.A.

Ok, so I got it and besides the radiator and all of the flushing and trans filter, they replaced the thermastat...I like that, so cool.

Well, I got it home, did some chores, and decided to go for a short ride with the girl. About 3/4 of the way back, the low-coolant light comes on! It goes off, and then later on and finally stays on, so I "B" line it home (not too far). The temperature gauge never showed over 208 or so. I pull up in the driveway and smoke starts pouring out the hood and the girl thinks the damn thing is on fire. There is some gurging and I tell her, no it's over heating.

I'm pretty upset...again. I will be calling Red Holman again tomorrow. This is getting radiculous. :(

Just stay with the chase. See if GMService will come to your aid since they monitor this frequency. Even a Rolls would give problems if the "service" was lousy.

I think the dealer has a problem! I believe GM warranty should of taken the case and No Charge you.. I believe the radiator is part of the warranty, unless, that radiator was NOT oem. AND if it is NOT oem you will tell them OK, I'll pay for the new oem radiator, the whole thing IMHO is tied if it is or not an OEM radiator, IF not then I'm afraid you are stuck with this whole fiasco.. They will NOT honor the warranty until the car is restored (at your expense) to standard oem status. I would escalate this to a "higher" level for further investigation & help... like starting perhaps with the GM dude floating about in here..:yesnod: One final thought, you being the second owner weakens your position IMO..:(

Thanks guys for the feedback so far everyone.

"They will NOT honor the warranty until the car is restored (at your expense) to standard oem status." This seems to be the case. Yes, I had them replace with GM radiator now, but they said the one in there was not and it make NO sense to me. They gave me "what they said" was the one out of it, but does anyone have photos of a "real" GM radiator and part identification so that I can compare? There is no 100% way in me determining if someone took out a real GM part and said it wasn't and gave me an aftermarket...there's no way I would know. I'm just upset because it's only 2.5 years with me and 24k miles and all on my dime, but sold with full warranty from the dealership and should be covered. How do I get a hold of GM warranty? After discussing with them, they acknowledged after they pulled the radiator and "determined" it was not GM, they never contacted GM, so right now, GM is not engaged!! :O Please let me know how to get a hold of them.

As an update...I just got a call about this recent overheating issue last night. They are saying one of the hoses to the heater core ruptured! They suggest the radiator (not GM) failure and trans fluid in the system contributed to this and so, will probably be my coin...again. They are going to send over two quotes...one for replacing 2 heater hoses and another for replacing all hoses! They suggest the trans fluid in the system may not have been good for the turbo either and are worried about it (and everything under the sun). Really, they are suggesting to get rid of it!

I'm a little behooved why the temperature gauge never never read about say 208 deg, though the thing was overheating and pouring smoke out of the hood? Any ideas?? Any thoughts on if the dealership fudged up and left air in the system or the overfill cap seal or something is wack and never allowed it to pressurize??

Let me know and your thoughts. :(

Does anyone have photos of an original GM Solstice radiator outside of the vehicle and/or have the part number(s) so I can compare it to the one I have??

I was talking to another salesperson at Bosch (where I work) and I he brought up a good point...the car I've had from the dealer since 19k. If it was replaced, the radiator failed within 19k miles?!?! NOT very likely. Even more than that, it was covered at that time under full bumper-to-bumper warranty! Are you talling me while under full warranty, someone swapped it out, not use a GM radiator?? For what? Save $50, of which they would have paid nothing for anyway?? This does not make any sense. Either, the dealership was mistaken or lied IMHO

Thanks in advance.

I believe if you go to the Werks web site they have pictures of their racing radiators with a picture of the original from GM.

Thanks. Still can't get a good photo. I'm trying to contact someone at GM and parts and me them. If anyone still has photos, please let me know.

As an update, GM didn't do me any good! They said they were going with the dealerships opinion, but no poof provided! As I said, I'm going to get my hands and compare them before let this rest. I don't believe it. In the end, I paid for everything up until this time out of pocket. It cost me $1300 the first time an $400 th second for the failed radiator hose (again, alledged to the rot cause item), so $1,700 out of pocket incluing 2 tows! That's 11-12 of the value o the car....or something that should be under warranty. GM may have lost a customer indefintely!
