 2010 Nissan Towing Guide    6 5th Wheel or Gooseneck Hitch – 
Mounted in the bed of a pick-up and 
designed for heavy-duty applications, 
these types of hitches are not available 
from Nissan but can be purchased from a 
professional supplier of towing 
equipment.*  
A 5th wheel or gooseneck hitch is 
usually installed and adjusted to meet the 
requirements of a particular trailer, but two 
basic rules hold true in every case. First, 
the hitch should be mounted a minimum  
2 inches forward of the rear axle 
centerline. Second, it should be securely 
attached directly to the truck frame. This 
installation should be done by 
professionals only, as it is very important 
to mount the hitch correctly to distribute 
the king pin load for the proper load 
carrying and sway control performance.  
 
BALL MOUNT  
A ball mount (also known as a drawbar) is a bar that holds a hitch ball and is inserted into a 
receiver-type hitch. Ball mounts come in a number of weight capacities (3,500 lbs., 5,000 
lbs., etc.) and sizes (1
1/4”, 2”, etc.), and can be 
weight-distributing or non-weight-distributing.  
 
HITCH BALL 
A hitch ball is bolted through a ball mount or  
a hitch hole in the tow vehicle’s rear bumper. 
The coupler on the trailer tongue attaches 
over the hitch ball.

under these conditions, hot water/coolant under high pressure may spurt out, possibly 
causing serious injury.  
 
5.  As soon as the engine has cooled to its normal operating temperature, visually inspect the 
drive belts for damage or looseness. A loose belt reduces water pump efficiency. Be  
careful to keep your hands, hair, jewelry, and clothing clear of the running drive belt  and  
other moving parts when inspecting the engine and radiator. Also check to see if the 
cooling fan is running, and inspect the water pump, radiator, and radiator hoses for leaks.  
Keep in mind, too, that if your vehicle is equipped with an electric fan motor, it may start 
without warning any time the coolant temperature is high. If you find leaking coolant, a 
loose or missing drive belt, or an inoperable fan, turn off the engine immediately. 
 
6.  If no leaks are apparent and all other components appear to be operating properly with  
the engine cooled to its normal operating temperature, check the coolant level in the 
reservoir tank with the engine running. Add coolant to the reservoir tank if needed. At this 
point, if repairs are required, go to the nearest Nissan dealer. See the IN CASE OF 
EMERGENCY section of your vehicle owner’s manual for additional information on 
overheating. 
NOTE – All Nissan vehicles have an engine protection mode, which helps reduce the chance 
of engine damage if the engine coolant reaches a specified temperature. See your vehicle 
owner’s manual for details.
