Hello,
Want to install block heater on my 2007 XJ8L, what are the options to connect a block heater in freeze plug .
Northeast Iowa and it gets cold here.

 

The V8 of the AJ series has no frost plugs in the block, only on the left side rear a screwed hexagon plug. I doubt that there is enough space for a heater.

An auxiliary or park heater installer could be an option.

Trouble lite, an old blanket with a 100 watt bulb, under the hood.
Helps out when its really cold.
Just keep the blanket away from the lite bulb .

 

Wingrider is on the money. Back somewhere in the Dark Ages, i.e. the '50s and '60s, my dad would use the 100w light (incandescent) under the hood with a blanket up above to keep our Volvo ready to go in the mornings.

My dad used to do this for his Nova/Chevy II 6 banger. He had a carport. When I moved to Charlottesville in my late 20s, I did the same for my girlfriend's F-10 Datsun, voted one of the most ugly cars ever made, but I digress. I had no carport. Snow was blown under the barely latched hood, and was melted by the light bulb. The cold water caused the light bulb to explode which ignited fuel system components. Whoosh. I called the fire department and they got the fire out before the F-10 exploded.

My girlfriend had taken my Olds to Richmond and upon return saw smoke coming from our property about 1/2 mile away. "Oh, how nice, Randy has a fire started in the wood stove". Nope. Insurance covered my foolishness and we ended with a better compact for her use with lower mileage and a fire extinguisher.
