Major Cooling System Issues without Warning Indicators on Recently Acquired 2011 Volvo C30-R

Post by balabaika » Wed Jul 24, 2019 1:43 am

About a month ago I purchased a 2011 C30-R with ~70,000 miles. It’s “certified,” and carries an aftermarket limited Powertrain warranty which is administered by the Toyota dealership. This is where I bought the car.

The morning after I bought it, I checked the fluids, and saw that the oil line was about an inch below the minimum line on the dipstick. I immediately returned to the dealer, and they added about 1.25 quarts of oil. The technician notified the supervisor, and he told me to bring the car back in 500 miles.  

About 10 days later while driving on the highway, I felt the turbo go out. A check engine line came on later in the day, but this was after several hours of normal driving, i.e., the car being turned on/off for errands, etc. The dealership looked at the car two days later and they noted a code 640c and that the turbo CAC tube had popped off. They reattached the tube and cleaned some oil off of it. 

About a week later, I went to check my oil and noticed that the coolant in the reservoir was about 4 inches below the min. line. I filled the reservoir and gave the car a quick drive to see if it held. The coolant had dropped again, so I added more and then stood and watched the reservoir (car off). The coolant dropped from the correct fill line down to that point about 4” below the min. line in about 10 minutes. This occurred while the car was off. There was no leak or smell and no discernible smoke, steam, etc. coming from the car. I filled it again and drove about 3 blocks. I immediately popped the hood after stopping, noting the coolant was once again at that point. I then stopped to check the oil, and as I pulled out the dipstick, the coolant went crazy. and temporarily started to boil and then settled back down to that same spot. The boiling started again, and this cycled a few times. I could see moisture pushing out where the lid screws on. As I watched, the reservoir itself ruptured.  

I got the go ahead from the dealer to take the car to an independent mechanic that works on imports. They replaced the reservoir and looked for codes. The car has been given the all clear. (They specifically noted that the temp. sensor was in good shape.)


Note: I live out in the sticks, and the nearest Volvo dealer is 150 miles away so if I do keep the vehicle, much of the maintennce would have to be performed elswhere. Also, my aftermarket warranty ties me to a Toyota dealership, so getting approval to see an experienced Volvo mechanic is difficult. However, I am planning to get a full inspection with Volvo in the next few weeks.  

My questions/concerns:
1) At no point was there a warning light/maintenance notification/check engine/etc to show something was amiss. The temperature gauge never indicated that the car was hot. 
2) Would the temporary lack of coolant have caused some degree of engine damage even if the vehicle is currently performing well?

The sales manager might be open to a buyback, but I’d definitely prefer to keep the car. Big mistake?

I appreciate your insights and advice.

My 2 Cents.

Too much stuff too early, especially with the coolant disappearing when not running then the reservoir blowing up? Is the floor board wet? Heater core or thermostat both blocked perhaps? Maybe it had a head gasket problem and someone dumped a quick fix into it. Unless you have time and want to take the time to deal with future issues send it back.

The longer you wait the less chance of a buyback. Did you see a Carfax before purchase? Sometimes you see consistent problems through out its span of services. You live too far too deal with these unknowns.

My last cent.
You need answers or theory as to what took place not just part(s) replacement. One last item, perhaps air in the system but why did the coolant get to a level for air to get in? A radiator flush, replacement, heater core replacement or head gasket?

Thanks for the reply

1) Floorboard coolant: Nope. No one seems to know where the coolant ended up.

The people that replaced the reservoir tank were guessing that the coolant was escaping beneath the reservoir cap.

2) Carfax: I've got one, but 99% of the report is related to titles/registrations; scheduled maintenance, and general servicing. At 57,000 it notes that "engine oil/fluid leak checked," but that's it.

However, the dealership from which I bought the car did replace the oil pan. (Granted, that info did not make it onto the carfax report.)

3) I asked at the dealership if they'd flushed the coolant and he said that they hadn't. The first mechanic I took it to for the coolant issue the radiator had been replaced. He thought it was bad enough that he shouldn't be working on it. (This all happened 100 miles from the dealership, so their mechanics weren't working on my car.)


In one sitting we added an entire gallon of coolant and watched it drain below the minimum line in a matter of 15 minutes. My car holds 10 liters, so it would have had to have been almost half empty.

Have you done a hydrocarbon test whether at the reservoir or at the tail pipe? That much coolant and no where to be found in/out/around/underneath could mean it went out the tail pipe.

The oil leak could have been a sign/symptom of a head gasket leak. Had head gasket problems on 3 separate occasions years ago on 3 different cars (THANKS MOBILE 1). Oil leak was the first indicator and not coolant.

EDIT: Finally, the exploding reservoir was not a good sign either.

My borrowed cent.

If you can't figure it out it could be high maintenance later. Best to return it before you fall in love with it. It's might be easier to let it go while you are still infatuated.

The other bad part is no one was capable of giving you an answer.
