    "Newbe" with a few questions

    I'm a long time car collector that just could not pass up a nice running 1987 Allante. But there are a few issues that I can use some help with. The power steering is at times hard to turn.( Like the power part comes and goes)The belt is new and the P/S fluid is fine. Does that mean the pump is bad? The ABS doesn't work. Is it o.k to drive without it? and last the DIC display shows just a rear light is out, Does that mean as the owners manual states that the every thing else is working as it should? The value that these cars offer in teams of looks and options is many,mant times what the purchase price is Thanks for any help

    Re: "Newbe" with a few questions

    Sorry I can't answer it all, but here is what I know. The brakes will work without the ABS function. You simply won't have the stopping benefits of the ABS. As far as the lights, you will probably find that there is one light out. There is a redundancy built into the system. Make sure you use the correct bulb. It should be a 2057 with a brass base. I purchased them at NAPA. The 1157 bulb which people often install can cause overheating and melting of the socket and lens. This is a very expensive repair/replacement. I can't say what the deal with the PS pump is. Good luck.

    NO NO NO !!!!

    ABS doesn work? park it and do not drive it until it is fixed. These brakes are not to be messed with.

    The response by moose is wrong. The ABS is the heart of the Bosch III system.

    An Allante w/o ABS is basically a car with 3 or 4 stops away from a total failure.

    It could be other things like the e-brake not fully released but until you get it all sorted out, do NOT DRIVE IT.

    PARK IT ...

    The ABS doesn't work.
    ^ This is a bit too vague to diagnose the problem, but I'm going to assume you haven't ran the car and maybe just turned on the accessories to find the red BRAKE light staring at you, in addition to the DIC reading "Anti-Lock Disabled" (IIRC).

    BEFORE YOU DRIVE THE CAR:

    1) Make sure the parking brake is released - the release button in located underneath the dashboard on the driver's side and can be tough to find if you don't know where.
    2) Start the car, and give it about a minute to warm up. If the car has been sitting for a while, this should charge the accumulator, which is necessary to run the brakes. After about 30 seconds, the light should go off and "Anti-Lock OK" should display on the DIC.

    If this doesn't fix the problem, DO NOT DRIVE THE CAR UNTIL IT IS FIXED!!!!! It is only a matter of time until the brakes totally fail. There are a few sites which offer parts and services regarding the Allante's Bosch III brake system.

    I could think of few things that would ruin a nice car ( And my day)like "total brake failure" I'll plan on finding the problem and fixing it myself. Worse case I need a ABS pump. Thanks for the input. By the way, Can your really can change the plugs on these cars? How many hours of work should it take?

    Re: "Newbe" with a few questions

    Good post and I may have to stand corrected but I'm not sure, my 1988 Owner's Manual, Section 2B, states "If the "ANTI-LOCK DISABLED" message is on, the car may still be driven. The conventional brake system will operate normally without Anti-Lock assistance". Thanks for the feedback. As for the spark plugs, the front four are relatively easy. The rear four are relatively difficult. I was not able to accomplish from underneath the car laying on my back. (One of them (driver's side) is accessible from the top if you remove the air inlet i believe). I plan on taking it to the shop for this

    Do the ABS diagnosis on the www.allantesource.com web site before driving car. The taillight message can be 2 different brands or wattages causing the message.

    I would not brag about the anti lock non function. This era of ABS has virtually no back up brake system in case of total failure. Every Allante that I see in a wrecking yard has had a front end COLLISION THAT PUT IT THERE. 90% of the time the light message has to do with mismatched bulbs (different brand, brass bases instead of silver) or simply not disconnecting the redundant module and reconnecting it to erase the false message. These bulbs must be 2057's and all be the same well known brand.
