The part is the same as a Toyota Camry or something like that. I think my Toy dealer sold it to me for ~$130. R&R took me about 1 hour total. It helps to have a 19mm (or 17mm?) crowsfoot. You can check the dimension when you have the part in hand. Replace from underneath. There is a good write-up somewhere on the interweb. -B-

Received the door controls, Thanks! Now I need the left rear tail light. The part that is on the body. (Backed into a truck today. :cries: -B-

I would like to pick up the driver side window controls. I am planning an "auto-up" electrical modification so I want one that I can take apart and tinker with. -B-

That is likely your problem. Also check the small wire from the negative terminal to the body ground point. -B-

Both the '98 and the '93 LS400 use 16" wheels when stock. Any "ratio" difference would be attributed to different tyre sizes between the 2 vehicles. They could be using the recommended tyre size for a '93 mounted on the 16" wheels from the '98 and there would be no difference. -B-

The above suggestion to disconnect the battery is what I would try. This will reset the alarm system and everything else. -B-

RT's responses are on target. To address your specific questions: Yes, though it will be an expensive repair. Probably in the $500 to $1000 range. If you cannot get to a Toyota dealer for the coolant and the cap then, at a minimum, you need to get some distilled water from any grocery store. I would worry about the overnight temps in SD at this time of year. You can pick up a cap at most any auto parts store. Yes, there is a problem with driving it with any cooling system failure. A 400 mile trip is out of the question until the issue is fixed. You will most likely ruin a very expensive engine. As RT mentioned, it might be as simple as a radiator cap that is not holding pressure; therefore "boiling" out your coolant. On the other side of the spectrum is the failed HG which is a serious problem and an expensive fix if you take it to a repair shop. The loss of coolant could be from a number of different things between those 2 ends of the spectrum.... thermostat gasket, radiator hose, heater hose, leaking freeze plug, leaking radiator, leaking heater core, cracked engine block, etc.... The first thing you have to do is determine the cause of the coolant loss, then go from there. Post back what you find and we will be happy to help. -B-

No. 15" tyres will not fit on 16" wheels. -B-

Yes, the same. Replied to your PM too. -B-

Toyota dealer had the alternator brushes in stock too. p/n 27370-75060 $12.67. They stock the serpentine belt too. p/n 90916-02586 $35.60 I also picked up a thermostat and gasket, PCV grommet and I should have picked up a few other bits like oil pan gaskets and the good 90915-20004 Toyota oil filters. -B-

Yes, and you can get them from a Toyota dealer. I can dig out the p/n if you need it but I know they use the same brushes as a 1997 Toyota Land Cruiser. -B-

This is good information, thanks! Does anyone know for certain which caps are responsible for the sticky speedo and tach needles? -B-

Yes. The loose battery terminal connection is increasing the resistance in the cable, causing it to get hot and causing the other problems. Your alternator cannot properly charge the battery; your electrical system is not getting the voltage and amps it needs. Fix this, charge the battery, and you should be good to go. -B-

I agree with Jify and others that recommend distilled or demineralized water. MY 1994 LS400 Owners Manual specifies distilled water as do almost all cooling system experts. I am also a fan of using Toyota Red for the reason that Jify mentioned; specifically formulated for our engines. It is a bad practice to mix coolants and there are a LOT more ingredients in today's coolants than just Ethylene Glycol and water. Our engines are all aluminum. My other Toyota (a 1997 Land Cruiser) has an aluminum head and cast iron block. These engines (the 1FZ-FE) are notorious for having serious cooling system problems created by mixing coolant formulations. So to keep your system in good working condition you should do frequent cooling system flushes (at least every 2 years) and use a premium coolant and mixed 50/50 with distilled water. When you need to replenish the coolant, use only distilled water unless you have the same brand that you used when you did the flush. -B-

Do you have the AZ part numbers? -B-
