I would like to hear from anyone with advice regarding engine replacement options for a 1990 Allante. To date, I've spoken to Cadillac who will install a new? crate engine for approximately 7500, I've considered a Jasper remanufactured engine for about 4500 installed. In both cases a 3 year warranty comes with the installation. My car is not perfect and I intend to use it as a daily driver. That being said, I would choose a professional alternative with a company known to back their product. I would especially like to hear from anyone who has had similar repair work done with lasting results. Money, is certainly a consideration. Thanks Jack
Unless you have built engines before, and have a lot of specialized tools and a stock of the consumables (sealers, cleaners, etc), you are better off reliability and price wise using a remanufactured engine from GM or one of the national rebuilders.
My car is overheating.............is this a typical problem? So from a serviceability standpoint I am considering a crate engine to ensure a starting from a known quantity. I am located in San Juan Capistrano, California.
Yeah, just because its overheating doesn't mean it's time for a new engine, or even a rebuild. Your radiator is probably clogged. Either get it roded, recored, or replaced. If that doesn't work, do it again, and flush the block.
In addition to a clogged radiator, cooling fan relays, cooling fan motors, loose/slipping water pump impellar, and thermostat all should be ruled out as the possible cause of your overheating. There are so many good used Allante' 4.5's around that I would not even consider getting a rebuilt one or a crate motor. The 4.5's appear to have a service life well in excess of 200k miles, with a few approaching or even beyond 300k.
