It's the same for all the years. But it's the electronic vacuum solenoid that craps out on these things, not the actual valve assembly. http://www.cygnusx1.net/supra/library/EPC/MKIII_NATO/parts/87240.html

Not at all, this isn't a low pressure light. When the light comes on, you still have enough oil to pull 1G forces on the car, without uncovering the oil pick up.

I don't remember all the details any more, but the overseas 90+(?) MKIII's did have a oil pan with a float sensor. I posted pictures and running oil heights etc about it on Supraforums a way back. I believe the float sensor is identical to the North American 1991 MR2 units. It works by having...

I just use small pair of vice-grips with a "curved nose tips" on the spring hose clamps, and it works well. I even changed the rear 90 degree elbow on the side of the road when it burst on me. (in the dark no less :aigo: ) You can usually first rotate the clamp with a screwdriver to a position...

Check your rear suspension bushings/pivot points. When they get worn out, there is lots of slop and the rear tires will steer out into a rather drastic oversteer under load. Jack up the car, and feel for any looseness holding the tire at the 12 and 6 o'clock position (up and down) and push...

Let's try again. Previous file was zipped with Winrar, this one with Winzip. The picture is too large to post directly.

Hmm, works okay here and I'm on a different computer from where I posted that file. This PC has no software for me to resize or manipulate the thing. Sorry.

The color doesn't matter, but the insulating properties of globbering paint on the fins isn't really good for anything, when it comes to heat transfer. But that wasn't part of the question. :)

All the accessory belts use K section, poly-V's. If that is what you're after, I scanned a page of the sizing on it (couldn't find anything online either).

It's the interior cabin temperature sensor. The hose sucks air in, so the sensor gets quick readings. It uses a venturi contraption to create the vacuum for the hose on the climate housing.

Black helps to radiate heat more efficiently just the same way it helps to absorb heat better. However in a car "radiator" or intercooler where the radiation aspect accounts for only about 3% of the heat transfer, it doesn't really matter whatever you do with the color. Convection (from...

If the CPS is faulty, or the wiring to it is shot, it will kill the spark, since the computer assumes the engine isn't turning over. One of the more common reasons for not getting any spark in my experience.

Hey SySt, I see you're still dreaming big! :) Unibody design is actually a very efficient way to create a structure (aka weight to strength ratio). What kills it is the impracticality of having a fully closed box. You have doors that open contributing nothing to strength, windows that offer...

I would suspect a small leak at the intake manifold somewhere. A tiny leak makes a huge difference in the A/F calculation at idle, but is basically a non-issue at higher loads, since the leaked percentage to total air ratio is so small then. Since the intake manifold sees very hight vacuum at...

Well, lucky for an inline six, the sides 1,2,3 and 4,5,6 are perfect, since each bank fires in alternate succession! Not so easy on other engines, but who cares about those? :)

The dual turbine inlet housing has two major advantages over a merged collector. It reduces turbo lag and increases engine volumetric efficiency by reducing exhaust contamination. Turbo lag: Each half of the turbine is connected to only half the cylinders of the engine. 2 cylinders on 4's...

Have your radiator cap tested, or just replace it. I haven't touched my cooling system in 2 years, and it shouldn't need constant maintenance. Mrnickleye that's exactly why the stock hose clamps are superior to aftermarket gear/screw clamps. They keep constant tension on the hoses, so you...

Remember, the timing can only be set if the TPS is adjusted properly. It doesn't quite make it clear enough in the TSRM. Set the E1-T1 jumper and watch the check engine light in the dash. If you get code 51, fix or adjust the TPS first, otherwise the ECU will not hold the timing steady, and...
