To my knowledge, Oldmobile did not make a stock 3.4 liter engine. I'm guessing this question is about the 3.1 liter V6 engine. On the 3.1 Liter V6, finding the thermostat housing is simple. While standing at the front of the vehicle, look to the right side of the radiator to find a large hose connected to the radiator. It will lead you to the thermostat housing. The thermostat is located inside the metal pipe at the other end of the hose. Exact mounting details vary with model year. Generally, there are two bolts, one above and one below the housing that must be removed to access the thermostat. The heat shield for the exhaust crossover pipe partially blocks access to the bolt heads, so some tricky tools are needed to remove it. On mine, I removed the EGR sensor and heat shield so I could access the bolt heads. Once removed, the thermostat is very simple to replace.
why
As with all engine configurations, the temperature is monitored from the readings of the water that is circulated within the engine block. A water pump circulates the water from the radiator to the engine and back to the radiator. The thermostat is always located in the water pump. Just look for the water pump and the thermostat component will be with it.
ypu may have a busted heater core or a stuck thermostat im not for sure.
Go to Auto Zone and have them both checked out for free.
I had to remove the air intake to get to it.Easy then.
Personally, I average 27.5mpg combined (city/hwy). The original window sitcker MPG ratings were 22 city, 32 highway. In the new test standards, that would be 19 city, 29 highway.
I have a 2001 OLds Aurora 4.0 and was quoted $5800.00 to change both head gaskets. Ouch! So I added sealer into rad hose and changed the thermostat seems o.k for now.
The ratio of width to length is 34, so W = 34*L The area of a rectangle is L * W, so using the ratio we get L * 34*L = 108 cm2 34*L2 = 108 L = SQRT (108/34) = 1.78 cm W = 60.6 cm
The spring side of the thermostat goes towards the engine.
34 fl oz = 1.0052 L 5 L = 169.12 fl oz 5 L is much bigger (in volume) than 34 fl oz.
You can test your 1997 Oldsmobile 2.4 liter engine oil pressure sending unit with a diagnostic tester. The diagnostic tester is the most reliable way to make sure your sending unit is working properly.
If the thermostat is open, the ohm reading will be O/L.
