2002 nissan altima head gasket problems
The Nissan Altima has always been a very praiseworthy family sedan. However, the 2002 Nissan Altima 2.5 had the
misfortune of being manufactured with very trouble-prone head gaskets. Due to the fact that the head gasket failure
jeopardizes the longevity of the engine, it will need to be fixed by an experienced auto shop. Here are some of the
most common issues that contribute to a head gasket failure on the 2002 Altima 2.5.
Aluminum engine design
The lightweight design of the Altima’s aluminum cylinder block helps to provide increased fuel efficiency and a better
on-road performance. Like most aluminum engines, the Altima’s QR25 engine must be kept at regulated optimum
temperatures at all times. If the aluminum cylinder block is allowed to overheat on a hot summer day, the head
gasket could suddenly blow at any given moment. Engine overheating will result in warpage of cylinder head and the
cylinder block deck, which then would require machine shop service. This overheating and cylinder head gasket or a
cracked cylinder head failure can occur in any car engine but will effect aluminum cylinder heads more often.
Thermostat stuck closed
A thermostat stuck closed must be taken very seriously. In a matter of minutes, the engine could begin to boil over.
If the person continues to drive the vehicle, the aluminum heads are at risk of becoming warped. Fortunately, the
good news is that a thermostat stuck closed can easily be repaired by a knowledgeable automotive technician. A
thermostat is one of the least expensive auto parts on an engine. If the aluminum heads become warped, the
engine damage will likely be very substantial.
Inoperative cooling fan
The cooling fan is a very important component, especially on hot days in Florida. In most instances, the coolant fan
in operative is due to a malfunctioning sensor. However, the coolant fan’s motor could also be faulty. No head
gasket is 100 percent safe if the engine is allowed to overheat. That is why a coolant fan in operative warrants
If your Nissan Altima is experiencing low coolant, there is a great chance that there is a leak somewhere within the engine. Although the coolant leaks could stem from a loose hose connection, they could also be caused by a blown head gasket. When checking for coolant leaks, you may notice that the oil exhibits a milky appearance. This is a tell-tale sign that the oil and coolant has mixed together. You should not even attempt to drive the vehicle any further.
