Blackout06LS

Vehicles covered by this write-up: 2005-2006 Cobalt LS

Installation Duration: 1 hour

Skills needed(1 being least and 10 being expert): 3

Parts you need to purchase:
Some sort of gauge pod(your preference)
Oil Pressure Gauge - Summit Racing Brand (Summit Racing Part # SUM-G2985)
Oil Pressure Sender - Summit Racing Brand (Summit Racing Part # SUM-G2987)
Autometer Adapter (Summit Racing Part # - ATM-2278)
Wire
Crimps

Tools:
Clothes hanger
Wire cutters and strippers
Crimpers
Vice Grips
Teflon Tape
14mm Open-end wrench(can't use a boxed-in)
19mm Wrench
10mm socket & ratchet

Directions:
1) Disconnect battery(located in trunk)

2) Install gauge pod onto A-pillar or whereever following their instructions. I used a a-pillar gauge pod and had to attach it with four screws and drill a hole for the wires as I'm going more for function right now.


3) Remove rubber plug on firewall located as shown. Slide clothes hanger through hole and find in the engine bay. Attach two wires to it and pull back through. This is your power wire and A/F signal wire. Mark them to keep them seperated.


4) Hooking up the power wire - using a crimp put the red wire(power) and crimp it into one side. The power wire you ran through the firewall will be connected to the other side using the same method.

5) Now adding power - Take off the fuse box cover and find the IP Ign fuse. A mini green 20A fuse. Strip off some of the wire and put this on ONE side of the fuse and re-insert fuse. Congrats-You have power now.


6) Hooking up the ground - Anywhere will be great, but I used the metal bracket that supports my clutch pedal. Just removed one bolt put the black wire there and bolted it back down.

7) Prepping Sensor for installation - Clean the threads thoroughly. Wrap a little teflon tape around the threads. Screw the adapter into place. Holding the sensor(be careful it will crush like a oil filter) place the 14mm on the provided area and with your 19mm securely tighten the adapter down into place. DO NOT OVERTIGHTEN. Now add some teflon tape to the adapter threads like you did the sensor threads. Place the copper crush ring in place that is provided with the adapter.
(no picture since I did not have my camera with me at work)

8- Removing the head plug. I tried to use a allen wrench as that is what you are suppose to use, yet the 7/32" was too small and the 1/4" was too big. As was the 5.5mm and 6mm. Take the vice grips and SECURELY get it on the plug. You will have to move some wires and all out of your way. And just break it loose as it is securely in place. I had trouble and I only have 10,000miles on my vehicle. Get the senser ready as you should have it already assembled as when you remove the plug you will lose some oil. Screw in the assembly and tighten down with your 19mm wrench. Make sure you crush the copper ring FLAT and do not overtighten as well.

TIP: Remove the center plug as it will give you the most room.

9) Hooking sensor to gauge(orange) - Now that you have the sensor securely installed. Run yet another wire from inside to the engine bay. This will be your signal wire for the oil pressure. Crimp a O connecter on the end going to the sensor and install with the provided hardware. Crimp the other end to your orange wire leading up to the gauge.

10) Reconnect battery and double check all wires.

11) Crank up engine and watch the pressure.
My car showed the following:
Idle: 30s
Normal driving: 50s
WOT Conditions: 60s

Disclaimer: Do not put gauge where it will affect your night time driving. I am under no reason responsible for where you install it. Please drive safely & responsible.

Cool mod. Why they thought the Cobalt shouldn't have proper gauges is beyond me.

Maybe a temp gauge should be next? (Yes I know its available in the DIC but I'd much rather have a gauge)

Blackout06LS

Next gauge is my nitrous gauge beside the shifter. I may put two there on the steering column...Volt and Temp I guess. That is later on.

SpecialK

Teflon tape? Why not use RTV form a gasket? Just askin, not bashin. I've always believed that teflon will break down eventually and one leak, but two a piece of that swimming around in your oil *shudders*.

When selecting a power source by tapping an existing circuit, know what you are doing. One side of the terminal is hot. If is tap that side, you are not fuse protected unless you use a separate in line fuse. Also, be sure you select a properly switched circuit (one that turns off with the key).

Blackout06LS

Yeah had several people say that in the other How-To of mine. I'm checking that fuse tonight to make sure its NOT hot when IGN is off. Turns off when you turn the IGN off too.

Blackout06LS

I've been using this stuff for years never had a problem. Friend had the past on the nitrous kit he sold me and you could see the gaps.

Oh yeah another tip leave the first few(that start) threads clean of the stuff. I do it so much I guess out of habit it doesn't even register.

cobalt06ss_sc

where is that port you screwed the oil pressure guage into?

joeworkstoohard

good mod. good mod. i wonder if the LE5 has the same setup.

Forseti

I have a tough time getting my bearings on the last two pics....like where in the engine it is...

Any way someone could post another pic that provides a better point of reference....?

cobalt06ss_sc

same with me...i think it's the drivers side of the motorbetween the motor and the computer. i think i found the plug BUT there is no possable way i can get a pair of pliers there to get that plug off. i think i might try and use a "T" joint off of my stock location. which you basically need to be Hudini to get to (it's under the supercharger and just to the bottom left of the oil filter and you can't see it and can barely touch it from the top). i think i have a plan of attack...i'm going to remove the starter to get a clear shot at it (i hope). i'm doing this on saturday so i'll let you guys know how it goes!

joeworkstoohard

i would agree... if you look in the fusebox pic, you can see the red wire off to the side and it running down to the engine.

css9450

In the very last pic, the oil-filler cap is visible at the front of the picture, all out of focus. The picture before that one is looking perpendicular to the last one, from over the driver's side fender.

copson

Do you think that the oil pressure sending unit is the same at the 2.2L

Blackout06LS

What exactly are you asking?

This How-To and pictures were made referring to the 2.2L. I own a 2.2L.

Brenn8402

would this be the same for a 2.4?? and also what is the diff between mechanical and electrical and do they both work the same for the oil pressure gauge? thnx for the help!

Brenn8402

anyone kno?

Blackout06LS

Not sure about the write-up. But you could use either one on your car. Get electrical...mechanical you'll have a hot oil line coming into the cabin.

Im doing my own install and I thought I could get some more pictures for those who want to do this themselves. Im waiting on my gauge pod from CA, but I have just received all my parts from Summit racing. Im installing a digital voltage and oil pressure gauge. (By the way, these gauges are like $30 each, and appear to be great quality. If you want to get gauges go with these summit gauges, they are great digital gauges.)



As you can see in this picture, the 2 gauges, the oil pressure sending unit, and the Autometer adapter you need. Ill post more pictures when I install it and try to get a better angle of the sending unit installed.

i just installed my oil pressure gauge from this how-to. It was a very good how-to. as for gauges i went with autometer shortsweep c2 electric. i went with oil pressure volts and water temp. got them on ebay for about 50$ each.

amomentsnotice

i have the autometer mechanical....im sure someone else here does too....

the adapter on the sender appears to be to small i havent tried it yet but thought i would ask before i tried.
So....
1. i would assume but i should install my mechanical sender in the same place right?
2. does the autometer mechanical adapter fit that spot?
i dont know where else i would/could install it anyways.

thanks for the help...

HatedCobalt

bump for this gauge install. i needed this to but hell will it work on a 07 lt2. i know that last one got me in the write direction...

DoubleClutchin_ION2

bump i have a mechanical too... but no idea where to put it....

the plug is a completly different thread
