Thinking about installing DEFA engine heater for winter... Reply #15 – November 25, 2005, 10:47:44 PM If the SEFI 3.8 is difficult to install heater hose heaters in, you could buy a magnetic oil pan heater. Up here they are used very often in the colder temps, but are not perminant ie: you must remove them before driving away. They cost $40 max and are sold under the name "heat magnet." Basically, you just stick them to the oil pan and plug them in overnight, or on a timer.Another alternative would be a peel and stick type pan heater which is more perminant.What is the coldest temperature in your region. Unless you get below -20*C, you shouldn;t need any heat source for the motor to start. Just the proper grade oil.On my car I have three heaters (coolant, oil pan, trans pan) but I doubt your climate is as cold. Either a coolant or oil pan heater should be sufficient.Edit: I just noticed you are over seas. I'll check ebay for those heat magents. Quote Selected
