Sorry Lamb, Im not so easily convinced.
Yesterday, a fellow GO Train commuter and I exited the train in Burlington in -30C cold.
I in my '96 Golf TD and her in her Jetta TDI. Hers fired up with a quick turn of the key. Mine fired up after a quick 10 seconds of glowplug heat. The sharp clickety-clack of an ice-cold diesel in the bitter cold is music to my ears.
In preparation for the cold did you (in order of importance):
1. Replace your glowplugs? Every 3 years for me.
2. Add conditioner to your fuel? Stop at a Husky and get some.
3. Buy only winterized fuel? Ask the station owner or stick with the name brands.
4. Get your battery tested or replace it if its 5+ years old. Get one with high cold-cranking amps.
5. Switch to synthetic oil? Delvac 5w-40 for me, get it at Walmart.
6. Drain the water separator under the fuel tank?
7. Change your fuel filter? Should change it at 60,000KMs. I'm lazy and waited till 180,000KM, no water found.
Go to tdiclub.com and learn (or ask) how to do all the above yourself. Don't rely on the dealer!
My next Golf will be an '05 or '06 Golf TDI-PD. 1200KMs per tank....bring it on!!
