How is the Cobalt oil cooled? Or is it? Is it possible to put an aftermarket oil cooler on with a thermostatic control?

for reference, I have a 05 LT. TIA

 

factory oil cooler. not 100%if the 2.2 are the same.

 

i think only the LSJ (probably LNF as well) have an oil cooler from the factory

 

yeah i edit my post while you were posting im not 100% on th 2.2's, the LNF's are just like the LSJ's i do believe

 

im almost positive the 2.2/2.4 doesnt have an oil cooler (its that triangular thing under the TB area, right? If it is, then no, the 2.2 doesnt have one)

 

yep that's the part....ok gotcha....

 

ok...

taking the general consensus is that the 2.2 does not have an oil cooler, what are the options for having one? aftermarket? OEM? how do the other cool the oil? water/air? air/air? are they thermostatically controlled?

 

The 2.2 does not come with an oil cooler, therefore there is no OEM cooler available, otherwise it would have come with one... The only cooling thats provided is by the bottom of the oil pan.

You can an aftermarket up and install it.

 

a way to have your oil cooled...

-m12x1.75" male to 1/8npt female adapter from autometer
- ~4ft of stainless lines
-a universal oil cooler
-a 90* elbow to return the oil into your oil cap


that method give u a uncontroled oil cooling system, meaning no thermostat to control when the oil is cooled, pros is cooler oil, cons is takes longer to warm up...feed the oil from the block gallery ports into the front of the car where u can have your oil cooler, than from the cooler run a line to return the oil to the oil filler cap...this way should u have to remove the system, u only place the gallery plug back, and replace a cap, vs dirlling and changnig oil pans etc etc

or you can return into the oil dipstick, but than u loose function of your dipstick...the oil pressure from the engine is enought to push the oil thru the lines and back into the engine...

 

could you not return it into one of the ports on the side of the head?
and hwo much more oil would be needed?

 

not worth it. engines these days are meant to run at a certain temperature. messing with the oil temp and thermostat could and probably will hurt the engine

 

but then again...by putting extensive mods on a car...such as a supercharger or full bolts and cams..you are making the engine run hotter and harder then it was designed...

ex, why would it not make sense to add an oil cooling setup to a 2.2 with the m62 setup if the 2.0 with the same has one?

 

2.2(insert DOES NOT EQUAL SIGN HERE)2.0

and no, modding a car and adding a blower to a 2.2 will not cause the engine coolant or oil temp to rise

 

then why do they have one on the lsj? its basically the same car

 

car yes, engine no. engine is a lot different.

i'm not saying don't put it on there. but its just gonna be a waste of money

 

not really that diff lol...pretty much the same in most respects actually lololol

 

so the timing, cams, intake ports, exhaust ports, vavles, springs, crank, rods, pistons, stroke, bore, transmission, ring tolerances, compression ratio, torque specs, and over all design are the same??? hmmm...insteresting.

 

Ive been wanting an oil cooler for a while now

 

not all of that no, BUT, the timing chain, cams (except for grind), valve springs, valves, trq specs, overall design, and i believe crank ARE the same


the 2.0 is basically a destroked 2.2 with a blower and some other minor diff



they are basically the same hahaha, i never said exactly, but most of it is the same yes

this is why they shair the same service manual engine wise and just have diff in them, and why you can bolt parts from one to the other
it is about 85-90% the same engine...

 

i didn't say timing chain, i said timing. as in stock. and sorry i laughed out loud when you said "cams (except for grind)" because...that defines what a cam is. so saying that two cams are identical except for the grind is like saying an apple and an organge are the same because theyre fruits, but everything else is different. and the only parts you can swap and "bolt on" are the intake manifold, exhaust manifold, and other misc parts like alternators and **** that have nothing to do with the engines performance.

 

actually if you get the right rods you can swap pistons (or other way around i dont rem)
you can also swap across intake cams...exhaust you cant only becase of the power steering off the end) the full SC kit, engine mounts, all other valve train, head gaskets are the same, seals and such are all the same, all of the timing components, cam gears, oil pans can be swapped across, pullies can be swapped (except the diff # of ribs on them). the timing isnt the same because it CANT be, that would be like saying the 2.2 and a boosted 2.2 isnt the same engine cause the timing isnt the same

you have proven my point, there are some VERY minor diff, but for 95% of that it is EXACTLY the same

 

hey if the kid wants to put an oil cooler on an otherwise stock LT. go for it. but when it does nothing for him. then i don't want to see a "this mod did **** for me" thread. the 2.2 doesn't have an oil cooler cause it doesn't need an oil cooler, putting one on there is a waste of time and money.

 

Given this...the only part in question would be the oil temperature, at temp and then when at different 'work' levels when the engine is being worked. Oil cooler has only one function, other than adding just a little more oil, and that would be to help maintain an appropriate level of oil temperature. Anyone have an idea of the oil temps?
