Car Forum / Toyota / Toyota Cars / December 2007frozen Previa engine
I was driving my beloved 91 previa with 338,000 miles on it today. I drove about 2 miles and it died, which was odd. I drove another mile and it died. I did this several times until it wouldnt even turn over. No lights came on. I heard no noises. It didnt overheat. The engine wont turn. The shaft that runs forward that drives the ac etc will not budge, but the alternator pulleys will move. Is there anything left except internal engine problems that arent worth fixing on this old vehicle? > I was driving my beloved 91 previa with 338,000 miles on it today.

It could be an electrical problem. Does it turn over when the car is jumped? I have a feeling that it is not an internal problem. You probably would have heard something. And you would not have been able restart the engine at all. I wonder if it was a bad battery and alternator. Anyway, that is just my guess. Jeff First check the battery and the alternator, given your starter would turn over the engine. It may just be out of juice. Have the battery and alternator checked free at a participating local parts store (call around), like AutoZone and NAPA. Check the engine oil. How's the condition? > I was driving my beloved 91 previa with 338,000 miles on it today. I > drove about 2 miles and it died, which was odd.

I took the battery home and put it in another vehicle, and it ran fine. The alternator is a used one I just installed last week before the 500 mile trip. But it isnt seized. the starter engages but doesnt budge. >I was driving my beloved 91 previa with 338,000 miles on it today. I > drove about 2 miles and it died, which was odd.

When you say that the separated accessory drive shaft (SADS) will not budge, did you put a wrench the front and try turning it by hand? For safety reasons, disconnect the battery before you do this. If you can turn the SADS and engine, the starter may be bad. If you can't turn the SADS from under the hood, try this: The SADS is connected to the front of the engine with 4 bolts. With a marker or dabs of paint, mark the bolts and holes so that the shaft, bolts, and holes go back exactly the same way, support the shaft with some wire or string so it doesn't dangle down, and disconnect the SADS from the engine and see if you can turn the SADS exactly 360 degrees. You are looking to see if the SADS is binding or the engine is binding. If the SADS rotates, try turning the engine over by hand by putting a wrench on the crankshaft bolt. If the engine won't turn over, you will have to drop the oil pan to see if there are metal particles in the pan.

They tried turning the SADS with a big pipe wrench, but it didnt budge. They said that it would be a 2 hour job to loosen the shaft (they thought you had to disconnect it at both ends), but they thought they detected enough wiggle in the alternator and ac pulleys to rule out those being frozen. I dont have 110% confidence in this shop but I sure hope they wouldnt make a mistake that would cause me to junk the van for no reason. What do you think?

Well, yes and no. I decided to have them pull the SADS to make certain. if the engine turns I will know not to trust them. I hope its going to turn. > > <...> > [quoted text clipped - 12 lines] > certain. if the engine turns I will know not to trust them. I hope its > going to turn. I looked at the oil again. I found a clump of metal fragments at the tip of the dipstick. I just changed the oil 9 days and 1200 miles ago. I think this one is history. I dont see much point in having them take the shaft off anymore. >> > <...> >> [quoted text clipped - 19 lines] > I think this one is history.

I figure if there is that much metal on the stick after 1200 miles, there is probably a whole lot more elsewhere in the engine. Even if it isnt proof the engine is frozen, its evidence of big trouble looming. I just dont see reason to hope anymore, do you? I wont pay for major engine repairs on it. >> >> > <...> >> [quoted text clipped - 34 lines] > reason to hope anymore, do you? I wont pay for major engine repairs on > it. If you are not going to pay for major engine repairs, cut your losses and say goodbye to the ride. SignatureRay O (correct punctuation to reply) |
