Assuming that you have no faults with your transmission, it doesn't matter - an automatic transmission will automatically switch down gear as and when it needs to. All the '2' gear does is not let you go over 2nd gear - which if you were heading downhill could make your engine over-rev...generally not recommended. So D should be just fine.

Get rid of the extra fans. If you're having to run fans constantly to keep the engine at the right temperature in the city, then all you're doing is masking another issue. You probably have several other issues. The engine temperature and the transmission going being able to shift into overdrive should be independent. It seems like you are conflating two ...

Yes, the normal route is to add sound deadening material inside the doors and/or on the floor of the car. A corolla won't have much stock insulation so you should be able to make some good progress in reducing it. This is a common project for people who are installing nice audio systems, so you should be able to find some nice walk-throughs on audio sites. ...

Replace the thermostat for sure, and while you're at it, replace the straight water with 50/50 antifreeze/coolant mix. Use the aftermarket fans ONLY during stop & go traffic in the city; on the open road they serve no purpose at all (ordinary wind from highway speed cools the radiator sufficiently in almost all cases). There's no need to remove the fans, ...

If oil drips on a pulley or a belt then the rotation of those objects could sling the oil everywhere, even as high as the bottom of the hood. Most likely an oil leak would have to be above these components and a good guess would be through something like a failed valve cover gasket. Another possibility is that it is leaking near the front of the car ...

The manufacturers specifications are the ultimate authority. It does seem like you can go 10,000 miles between changes with synthetic oil. As long as the Castrol oil you've got is up to the same standard as Toyoto Synthetic, you're probably good for 10,000 miles. As to whether you need synthetic, if Toyota says you should or must use synthetic, you need ...

I was able to see the grounding points by crawling under the dash. The grounds looked visually good, the screws are tight. So, I tried replacing the 12V power outlet with a new aftermarket outlet. The issue is gone. Strange that the one bad outlet actually caused both outlets to blow fuses when power was drawn.

If you're carrying a high load, L is best. The gears work as follows: D = use whichever gear the computer decides/ Useful for everyday driving. 2 = use first or second, depending on speed. Useful when carrying high loads at low speeds. L = stay in the lowest gear. Best for carrying high loads up steep inclines.

I'm looking at the 2009 Corolla: Scheduled Maintenance Guide that you can find on the nicely organized Toyota site. The closest thing to a fuel induction service is an inspection of "Fuel lines and connections, fuel tank band and fuel tank vapor vent system hoses" every 30K miles: Visually inspect for corrosion, damage, cracks, and loose or leaking ...

I'm hoping you may have missed a zero in the recommended service interval in your question. Modern cars don't even recommend oil changes more frequently than 5,000 miles, so an induction service every 3,000 miles is just crazy. Some dealers recommend induction service every 30,000 miles, but even then, I feel this is just a money-maker for them, and I ...

I hate to answer my own question but did eventually figure it out. Here are the more complete steps to swap the belt: Prerequisite: locate a belt diagram or draw your own before starting. Remove the plastic engine cover using 10mm ratchet - this will allow easier access to the tensioner / belt on the left side of the engine. Find the bolt head that is ...

This is probably something you should take the car to a shop for. It sounds like a problem with the evaporative emissions system. Your tank is a completely sealed system and when you are pumping gas it needs a way to vent the gas fumes from then tank because the gas flowing in pushes the fumes out. There are vent lines and solenoids that run to a charcoal ...

I've done a quick search and found this image for a 1991 Corolla, manual, sedan, for the canadian market. You have 2 bolts to remove, the one on the top of the pillar and the one that attach both end of the seat belt. They may be hidden Under some plastics panel. It should be an easy task but make sure to tighten the bolt back!!

"When using cruise control and pulling the lever for acceleration RPM goes all the way up giving a sudden push to reach the desired speed." That's an important characteristic. That means one of two things: Either (a) your accelerator cable is running into an obstruction that prevents it from opening the throttle further or else (b) (if that car happens to ...

I agree with the suggestion to fix the underlying cooling problem. Your vehicle should be able to handle tropical temperatures, even in slow traffic. I also agree with running antifreeze for the anti-corrosion and anti-boil properties. However, until you get the base problem figured out, you could continue to run plain water, as you may be having to do ...

Price sounds reasonable to me. Alignment definitely has an issue on that left rear corner. I can't tell across the Internet if it really needs shims, but it doesn't seem unreasonable. Many cars have very limited adjustments on the rear. They're not supposed to move much back there. Any change there is typically due to damage (hitting a curb or even a ...

I second everything jzd and Allan Osborne recommend. I would also suggest that you clean the excess oil off before re-filling. Once you've refilled the engine with oil let the car sit for a couple hours and do a visual inspection to see if oil is leaking again and if so, from where. That will help immensely with troubleshooting. If there is no leak ...

First job is to refill the engine with oil. Check for the correct oil in your vehicles hand book or ask at your local parts counter. Check with the vehicles owner for a history of any oil leaks. Do not start or drive the vehicle without oil. Check for the oil filler cap having been replaced correctly. Check that the PCV hoses are in place and in good ...

The closest I've seen to problems with the tensioner assembly is oil leaking: http://www.paulstravelpictures.com/Toyota-Corolla-Timing-Chain-Tensioner-Oil-Leak-Repair-Guide/ If the Toyota service shop already repaired it, I would have a conversation with the manager about what he/she thinks they might have done wrong during the first repair to make the ...

I finally took it in to a Toyota dealership. They said it was the overflow control valve (OCV); it's inside the gas tank, and requires replacing the entire gas tank, about $1000.

One thing to check is the EVAP system. If your gas tank is overfilled you may be getting some fuel in the charcoal canister. First, make sure when your refuel, don't overfill your tank by trying to 'round up' to the next dollar, stop when the pump handle shuts off. Some other things to check may be your refuel check valve and fuel cutoff valve ...
