It used to only take a couple minutes or so and now it seems like it's doubled. Any thoughts? I have a 1987 a57chevy43 02-18-2010, 11:17 AM Possibly a faulty temp sensor. Could it be the weather is just colder than usual. Slick100 02-19-2010, 06:58 AM I would say the temp sensor too. ex-x-fire 02-19-2010, 11:10 AM T-stat might be slightly open, very common. calvins88c4 02-20-2010, 06:52 PM :goodpost: Thats what mine did.
