I know I wouldn't want to work on my car in the wet and cold of the mid or east coast. Here is cali, are weather is getting cold be still its sweater time and just so happen to have a car working on hoodie that I use...
Ha, car repairs and funerals seem not to come at convenient times. My first 1993 had indications of needing a clutch replacement in late Dec early Jan of, I think 2009. Yes, Colorado get's cold, but this was one of our coldest times.
One of my daughters left her car outside so one of my sons and I could work on it in her UN-heated garage. I was grateful, of course. But it was gonna be a cold cold job. Well, we built an enclosure/tent out of plastic cloth over our working area, and put an extra lamp under there. Not so much for the light, but for those of you who don't know, those lamps create HEAT.... and it made our work bearable.
Oh, the clutch job turned out NOT to be a "clutch job", it was a pilot bearing.... poor installation by PO, or NEGLECT by PO [did their mechanic fail to replace it on a previous clutch job?]
We learned the full impact of those lamps years ago when working in an unheated garage on a less intensive, ordinary job where we needed extra light; sheeesh, it got too warm in there, had to remove our coats. No, it wasn't as cold as the clutch work, but it was cold outside, and VERY warm in our work area.
Cheers, and Happy Thanksgiving to all
