Acquired an 03 Mercedes CLK320 Cabriolet. Started off as just needing a commuter car. Ran across this low mileage car and got it for a song. Question regarding the convertible top. Will "excessive wear" be caused by dropping the top each day? Really like it with the top down. 1 button...

Just bought a 2003 MB CLK320 (88k miles) for a commuter car. Better than my suburban on gas. Small car, but comfy seats. Has a cool feature on the climate control. Button labeled REST. It's a residual heat function that turns on a small electric cooling pump (I think) and runs the hvac fan on...

Just got a 2013 suburban. I noticed the sides of the radiator had rubber flaps(air dams?) that have deteriorated and are not in place. This creates a gap about 4" wide and 14"tall at each side of the radiator. Thus allowing some air to enter engine compartment at the sides of and not through...

While waiting in a vehicle line idling for about 45 minutes (for the city dump) car started running hot, 230 degrees, AC working poorly, barely cooling the air. I turned off ac. Slowly cooled back to normal 210. New cooling system, always runs 210 no matter what. AC can freeze a side of beef...

I thought I might have had a cracked head leaking coolant into the crankcase so I got an analasys. No issues with heads, all was good. Not too many miles on the oil, just under 2000 miles, but here it is.

Recently found I was about 10-12oz or so low on coolant. Searched all over but could not find a leak. I began to think my 03 suburban was plagued by the dreaded cracked head which apparently leaks into an oil passage.?. So I ordered a Blackstone kit with TBN confident they can let me know if I...
