I have an 87 5.0 xlt , I was looking to see if it had a block heater, couldnt find one... Usually i have found them coiled up behind a headlight or somewhre up front. I know that it was probobly an option, (they should come on every vehicle standard) Just wondering if ford had tucked them away somewhere . I didnt look to hard its about 4 degrees outside and the garage is full any suggestions?
My '87 doesn't have one but it's spent it's life in GA, straight from the factory. I've heard that many vehicles meant to stay up north came with the block heater but I don't know. There has to be an aftermarket part that you can screw into the block or put where a freezeplug is.
Many of the Fords produced down south didn't come with factory block heaters. Most part stores will carry a block heater. To install it, drain the coolant, punch out a frost plug (Ford recommends putting it in the rear of the passenger side head - I found the easiest is the one above your starter), slide the block heater in and tighten it up, and then refill the rad. I had to install one on my 88 Eddie Bauer when I took it to Winnipeg, MB. Make sure to bleed the air from your cooling system when you refill or your heater won't work worth a damn!!
Switch to 5-30 or 10-30 synthetic oil and you won't have to worry about plugging in until the temps drop below -25F. If the engine is in good shape,I would consider using 0-30 or 0-40.I live in centeral Manitoba and my Bronco almost never gets plugged in.
Dwoodler has the right idea. I installed one (freeze plug version) on my 86 and have never had a problem since! I think it cost between $12-$15. Rear passenger freeze plug is the easiest to get to, instruction swith the unit are straight forward.
