Thanks for your input. I'm not sure that is a problem with snow. I rarely ever have snow on my vehicle. It's almost always parked in my garage or a parkade. It's starts as soon as I leave the drive way, that's when the first big bang happens.

I've also noticed that the floor vents are weak. I've used Bi-level many times (as someone had recommended in this thread) and have still found it to be really warms blowing out the dash but cold to the point where my feet start to freeze by the floor vents. I actually had it at the dealer last winter becuase I thought there might be a problem with the way the air is split and deflected. They tested it and said everything was fine though.

I'm hoping that it won't be too cold much more because if I don't hear the clunking noise I'm a little less concerned.

 

Black Beauty, There's something like 1.6 degree F per 1 degree C. Some when you going into the freezing values at some point, around -40 in this case, the values are the same.

 

I would die it that cold weather. Sorry but to qoute a line from the TV show In living Color....."Homie dont play that"

 

It's cold again today, yesterday we broke a 110 year old record low temperature for the day of November 27. Previous record low was -28C.

 

Yeah, we're cold here also. It's 65 F.

 

I can not remeber the exact temp., but most of all u.s.car manufacters design part to reach -40 degrees F. Anything colder than that, and your on your own.
I know our engine coolant control valve thats we sell to ford for its trucks only has to reach a tempertures of -40 degrees F. Also our 4WD actuator that we build for GM only has to function down to -40 degrees F.

Also according to Volvo, from past meetings.....Most shocks oil starts to breakdown at around -25 degrees f. "From memory"
You damn shocks are probably frozen.
How volvo explained it to our company.
The hydraulic fluid inside a shock does not freeze under normal circumstances. However, in severe cold weather the fluid may get so cold it will not flow through the valving inside the shock. Hence, the hamering effect some customers complain about it subzero tempertures.

Hope that helps.

 

Thanks for the information MD. I assumed that fluid freezing was the case. Luckily this bitter cold does not come around very often.

 

Dam that's just a little chilly!! 80+ !!!!!

 

I was actually going to ask, I can't remember at this point, does the HHR with the upgraded suspension come with gas or fluid filled shocks? I'm assuming they are fluid filled.

Would gas shocks be better for this sort of bitter cold?

 

Damn that's cold ... I noticed the same problem with the floor vents here in Pennsylvania - and it hasn't even gotten below 32 deg.F much yet. Took mine back to the dealer and got the same answer ... "Its working as it was designed". Hell even with the floor vents on for 20 min. my face gets warmer than my feet from the leakage in the defroster. I posted this in another thread and was told to wear two pairs of socks... . Sorry, now returning to suspension problem...
