Definitely avoid doing it the old way--where you breathe in and out of a tube. It has been linked to lung cancer and worse.

It is 23:1.

Where is the starter relay switch on a 94 Corsica V6 yam

It is R134. The port is either on or close to the receiver dryer or the shinny can thing in the right rear of the engine compartment.

No, actually a 1988 model year vehicle would have come from the factory with an R-12 system. If you're not the original owner of the vehicle, I would strongly recommend that you have a refrigerant purity test done on your vehicle - many R-12 systems were converted to R-134a, but retained the R-12 schrader valves.

Not sure what you mean by a "breather pipe".

In the old days--before emissions, engines had breather pipes which vented blow-by and crankcase vapors directly to the atmosphere. Car co's wised up in the late 1960' s or thereabouts, both about the environment and increasing engine life, and installed Positive Crankcase Ventilation (PCV) systems.

Basically, blow-by (hot gasses, unburnt fuel, and condensation from the top side of the pistons that literally blows by the piston and rings, even in new vehicles) is very corrosive and damaging to metal parts in the bottom half of the engine. It also contributes to pollution.

PCV systems are set up to draw air from the vehicle's air cleaner down a tube, typically into one valve cover, through the engine head's oil return passages, through the crankcase, and into another tube on the other (we're talking about a V-6 or V-8 here, but they all work similarly) valve cover. This "exit tube" is controlled by a PCV valve which has a weak spring to prevent air flow going the wrong way, and to keep the PCV system from adversely affecting the engine's performance under certain load conditions.

The exit tube is ultimately connected to the carburetor or air horn of a fuel injection system, so there is vacuum on the exit tube. Thus while the PCV valve is open, the system "flushes" blow-by gasses and other crankcase vapors through the exit tube, and into the air-air/fuel mix path, where it enters the cylinders and is burned.

The V-6 3.1 Corsica's PCV valve is on the rear valve rocker cover, and the vacuum ("exit") tube is a model of crappy engineering, an S-shaped rubber hose that requires that the intake air plenum be removed from the top of the engine to replace.

the motor could either be good or bad depending on how its been maintained.if its been owned by another person u realy cant answer that question. even if u ask the prior owner if its been properly maintained and had regular checkups and maintance the chances are very likely that the persons going to lie to u and tell u that i was done yatta yatta yattaso the only way you are going to find out is if u take it to a professional and have them hook there machine up to it and take it for a test drive. other than that you really dont know......

It's located in the center of the front floorboard way up in front. If you have carpet there pull it down and there are several bolts the you will need to take off. Once you get them off and pull the plastic case off you will be able to see the heater core. I think there is a strap that holds it on in there just take it off and you should have two hoses coming off the heater core, take them off and hook them up to the new one and finish up.

Make sure that you have the coolant r134a because the government banned the other coolant used due to chemicals that are worse for the environment. Corsica's usually take 2 1/2 cans if the ac is blowing warm inside the car. Oh , and you could get fined if you are caught doing this on the street.

You will need a hose to attach to the low end of your cooling lines. The low line is at the back of the motor, closest to the firewall. You can purchase the hose from autozone, napa, etc. (Coolant line is silver metal hose with plastic screw on plastic cap)

Follow the instructions with the kit. The hardest part will be getting the hose onto your cooling line because it's under pressure and your motor will be hot.

1. Just make sure the hose is securely attached and be careful to not burn yourself.

2.You'll need to screw on the can of coolant to the free end of the hose until you cant turn anymore, that pierces the can open and locks off the line to keep the coolant from spilling.

3.Then turn it back all the way to open the line and let the coolant flow. About 10-15 turns.

4.Then you have to turn your ac on inside the car and this will suck the coolant into your ac line.

5. Go back to the can and hold it until you feel that it is empty- it should be ice cold and empty.

6.Quickly take off the empty can quickly and attach another, turning to pierce the can and turning back to open the flow.

7. QUICKLY remove hose and place cap on the line.

8. Drive your car around for about an hour. (Keep an eye on the temperature guage.) This will allow for the line to expel any air and for the line to circulate the coolant good.

**As you add the coolant go inside the car to see if the air is beginning to blow colder. If not, this could indicate that the coolant is leaking out. You can actually see if it is, as it is neon green. If that is the case, you may need to replace the clutch compressor unit ($260-$315, or $75 used at junk yard. Better to buy it new)

No idea to be honest, but i have a 95 Corsica with a similar problem that will turn the Service engine light on after a while of driving highway speeds, or after reaching highway speeds and slowing down again. After getting the code read i found out it was for the EGR valve sensor. Basically meaning that its positioning fine at normal in town driving but not working as it should at higher speeds.

Again i can't assure you this is a positive solution but i would recommend running your car as you would normally get on the highway and then while the light stays on going to AutoZone (They will run service engine soon checks for free) or a mechanic you trust. hope this helps.

I have a 1990 corsica with the same problem. After the engine was warm the tork lock would not disingage. I disconected the tcc valve. This caused bad gas mileage. I hooked it back up to see if I could find the real problem. What I discovered was the tcc was working under excelleration, but not under decelleration. This fact led me to beleave that to disingage the tork lock you need good trans fluid preshure. I did an experiment, I got on the interstate drove until I was shure it would malfuction when I slowed down. When I got off I55 I realised the tork lock was still engaged and I was in first gear. I then shifted to nutral, and excelerated the engine to above 3000 RPM. I then shifted to drive, and the tork lock was disingaged. Fluid preshure is the key. I installed a trans cooler broblem solved!!!

seriously it is 1-2-3-4-5-6 for all v-6 engines in the berreta or corsica wolverine

I have the same problem and have been serching for an answer for two months.What I found out today the anti-thief system is tied into the radio. A professional installer has a by-pass kit[w/thin gauge wire]. My concern is what to bo about the key lock cylinder? If I still need to buy a a dealer cylinder, I found prices for aboyut $250.00 w/o installation. So if your Tanoe has a reasonable priced cylinder and sensor[at any local parts store,] I'd replace those items. For me I'm going to use a push button to start the car untile I find a used cylinder lock and ignition switch.Hope this is of some help to you, aagsr

my hi/lo switch just crapped and the lights died completely before the switch quit for good. Maybe that's what happened to you? If anyone knows how to change the switch on a 1990 3.1L Corsica please post.

Thanks

I had same problem on 89 Corsica. Hi/lo switch under dash and hard to take off unless you remove steering column so I unplugged switch and plugged in new switch and set new switch on low beam and wired switch to column. Now have low beams but since new switch not connected to activator rod (which goes to turn signal handle) as old switch still attached to activator rod, only have low beams. New switch about ten dollars. On 89 there is ground wire on body in front of battery. First, unbolt and clean ground, as bad ground can make lights inoperative so if you are lucky, cleaning ground could solve problem.

birds and fish, along with insects, geckos and lizards.

plants:Ferns, like tree fern, particularly prize these humid and windy places.Polynesian vanilla Coconut tree and heaps more

I can think of Three things,
1. Thremostat stuck open.
2. Poor quality radiator hose or the spring inside is bent or missing.
3. Low water level in radiator.
Good Luck

If it's 3-speed gearbox, it's 3T40. If it has 4 speeds, it's 4T60E. See http://www.gmautomatictransmissions.com/transmission_applications.php.

thermostat on 3.1 engine is located on driver side right behind manifold crossover. remove air breather. u need 1/2 inch socket for left bolt, right hand bolt is very hard to get to.

i just changed thermostat for daughters 98 Malibu with 3.1. good luck

pressley

Amateur with idea: Mine started out that way, became more often, then no sound/effect when I turned key. Eventually I had to replace my starter. Bought starter at CarQuest (you will get some money refunded when you return the old starter back to store). Mechanic charged me $60 to put it in, only took him a few hours between other customers*-*

YOUR TALKING ABOUT TWO DIFFERENT SYSTEMS, ENGINE COOLING FAN AND AN INTERNAL HEATING/AIR CONDITIONING FAN? WHICH IS IT?

One symptom of a bad time chaining is a shaking when the engine is in idle. The valves in the engine may also clatter or knock and the car could also backfire.

I believe there is one on the driver side buy the brake pedal.And one under the hood.I used to own a 1993 a long time ago a Beretta and a corsica.

The one on driver side is a panel on the side of the dash just as you enter the car. It's held closed by velcro.

Mine does not. Perhaps you a low on coolant.
