How do you install an engine block heater on a 1990 Honda Accord EX?
I had to replace my block heater on my 89 Accord and the plug/location for the heater is in behind the distributor. I had to remove the distributor from the engine block and then removed the old block heater. It is an easy do it yourself job but you have to be carefull to reinstall the distributor exactly the same way it came out. Hope this helps.
