block heater is pretty good. Oil heater on the pan is hard to do because the gearbox is in the way and there is no space for it.I have a 1985 900 Turbo. I read some previous posts regarding block heaters (pre-warming the engine in cold weather). Any ideas on other types of heaters, e.g. oil dipstick; magnetic, wrap, etc.?
Not really. I think it (the Saab one) just screws into the block drain fitting under the exhaust. If anything it would be by far the easiest option.Keeping options open; does the installation of the block heater require a special tool, a special procedure, or any special precautions?
I used a line heater in an old Scout. Installed in the lower radiator hose (which I think there's room on the 900 as well) the heated coolant rises up through the block creating circulation. Worked well for me--the bonus is you have near instant cabin heat/defrost. It's easy to install (just cut out a section of hose) and you can take it with you when you replace the car...Thanks for the replies; I'm nursing this old car along and I'm leery of things breaking (like corroded plugs/block heater access, etc). A friend suggested a heater in line with a radiator hose. If anyone knows pros or cons on this, I'd appreciate it.
