Chevy did not use an inertia switch. It don't have one.
I just called Toyota, it uses 75w-90 Gear Oil.
SAE 75/90 (synthetic is better but not required)
The Toyota Corolla requires Dexron III transmission fluid in automatic transmissions. Corolla manual transmissions, on the other hand, use Hypoid API GL-5 (75W-90) for the 4A-FE engine, and API GL-5 (75W-90) for the 7A-FE and 1ZZ-FE engines.
About 90 to 100 thousand km run
You can use Dexron II or III for an A/T, and 80W-90 for a M/T
I am 100% sure that the rear springs from a Camry can fit a Corolla (case in reference 93' Camry springs on 90' corolla)but I haven't tried the front springs yet so I am not sure about that one
Gear Oil API GL-4 or GL-5. 75W-90
Depending on the model/engine type, the cylinder head torque specs for a 1990 Toyota Corolla are: For the 4AFE (1.6) coupe/sedan/wagon: 44 ft lbs For the 4AGE (1.6) GTS coupe: 1st: 22 ft lbs 2nd: additional 90 degrees 3rd: additional 90 degrees
standard torque on any head is about 80 lbs to 90 lb torque
The torque specs for the head bolts on a 1997 Toyota Corolla goes in three simple steps: step one- tighten the bolts in the the correct order to 22lbs step two- in the same order, turn each bolt 90 degrees step three- go through and again in the same order turn each bolt in an additional 90 degree.
It is on the drivers side floorboard, up under the dash near the fuses. It is a black piece of plastic with a red switch on top. Get a flashlight, you should see it.
