1993 Toyota Previa - Page 6 - Answered Questions & Fixed issues

No spark from where? If not at the sparkplugs, then go to the coil and just check in reverse...

Before you do that, after you changed the thermostat, did you bleed tge air out of the system? If not, you'll still overheat. Click my screenname, go to my Tips and Tricks, and follow the procedure there for burping the cooling system and see if that fixes your overheating problem.

it has a leak somewhere ?? water pump

Do you know what trouble code the Previa is throwing?
You may want to check the little 1/2 inch diameter passage in the throttle body that connects to the EGR valve. If that passage gets clogged (and it usually does), It'll throw a check engine light. I was having a similar problem and found that this passage was completely blocked with carbon deposits. You can clean it out with a small screwdriver and a shopvac.

There is a hatch under the driver's and passenger's seats. The driver's seat hinges up to access the oil dipstick and throttle body. The passenger seat must be removed to access the hatch below it. Sounds difficult, but there are only 4 bolts to remove.

I believe its location is printed on the underside of the fusebox cover. If you haven't found the Previa fusebox, it's in the center of the dashboard just above the radio.

Depending on mileage and how well maintenenced the vehicle is, the valve seals within the cylinder heads can get worn out. When they wear out you can get smoke from your initial start up. If it is a persistant smoke then most likely it's the piston rings that are worn out.

I wouldn't replace just the wiper rubber... I would replace the whole wiper. They come off pretty easy, there is a metal rod that extends from below the window to the piece that holds the wiper. At the end of that metal rod is a plastic clip, usually if you slide a small straight edge screwdriver under the bottom side the clip it will all slide off. But be careful, they are spring loaded and can chip and or crack your windshield. Most auto parts stores will install them for you if you're nervous about it. After you remove the old one, the new one slips right on. It will click into place when you get it right.

You may need to replace your thermostat or heating coil.

Some SUVs the rear shocks bolt to the floor panel and some bolt to a hanging bracket from the bottom. The bottom of the shock always uses the rear axle bracket. Make sure the car is jacked up safe with jack stands and level surface

thermastat could be stuck closed allowing no heat.also heater core could be plugged

The Previa has a special hydraulic center clutch. To convert it to rear wheel drive it would be necessary to replace the whole drive train. Disconnecting the front drive shaft on a 4 wheel drive vehicle will only save you a very small amount of of fuel. The only way to see a substantial fuel savings is by disconnecting the front drive axles from the wheels. This is what manual hubs do and that is why they are still popular.
To see even more fuel savings you would need to remove all of the front drive components and this would remove several hundred pounds and ever bit of weight that you can remove adds up to more fuel savings. But now you will end up changing the center of gravity and the balance of the vehicle.
I have made the assumption that you are trying to increase the fuel mileage of your Previa. Is this correct??
So in the long run you are looking at a major rebuild of your Previa. It would be less costly and less of a headache to go buy a smaller more fuel efficient vehicle.
I know that this isn't the answer you were looking for but this is the proper answer. I hope this helps.

All strut mounts are found at the top of the strut assemblies. The mount is what holds the strut assembly to the vehicle.
