There are different types of block heaters. You can place a magnetic heater on the engine block, transmission pan, or on the oil pan. A hot pad heater can also be placed on the oil pan or transmission pan. An external engine oil reservoir heater is plumed into the oil supply and pumps the oil through the heater and keeps it at a set temperature. A freeze plug type heater is installed by removing one of the freeze plugs and replacing it with this heater. It then heats the coolant, thus keeping the engine warm. Then there is the lower radiator hose heater that also keeps the coolant warm. And there is also the dipstick tube type heater that you simply install by removing the engine oil dipstick and replacing it with this type heater. There are multiple variations of all these type heaters.
Usually the block heater is in place of the passenger's side rear freeze plug
It's unfortunate that you posted your question on answers.com, likely the last place you'll find an actual answer ...
no ! And there is no place to install one .
Any NAPA parts store can supply a block heater that will keep your diesel toasty.
drain coolant from radiator, remove one of the frost plugs in engine block, install block heater in place of frost plug, refill radiator with coolant.
It may or may not, block heaters are not factory installed unless special ordered.
If it has a block heater it will be installed on the passenger side of the engine , in place of one of the freeze plugs ( core plug , expansion plug etc )
the block heater takes the place of your freeze plug, in this case you would need to locate and remove the correct freeze plug and replace it with the block heater plug, plug in the cord and route to appropriate location, done
There are several types but generally the best are either the in-line heater hose style or the freeze plug style. If you use the in-line heater hose style, just cut the heater hose, put the block heater in place then make sure the heater control is left on at night. If you use the freeze plug style you'll need to remove an existing freeze plug and put the block heater in it's place. The magnetic style block heaters are not recommended. They seem like a good idea but they're more trouble than they're worth.
Usually in place of the passenger side rear freeze plug.
It must be a diesel, You will find it in the side of the engine block were a freeze plug went. I think it will be on the driver side just under the head. If it is a gas engine, it does not have one. Unless someone put 1 on it, if so it will be in the same place.
