HT4100 4.1, 4.5, 4.9 Discussion, Requesting 4.5 89' Info in Cadillac Engine Technical Discussion; Hi all!
I'm new to the forums, and already have a question
I was considering purchasing a 89' Fleetwood Caddy, ...
I think youll be pleased with it, i cant help you out with scematics and such but i can tell you that ive had my '89 Sedan Deville for almost 3 years and i love it, the engine is strong, perfect for tooling around town and its a great highway engine, just floats along, i know its a 273ci horizontally apposed 90degree V8 engine putting out about 180HP give or take and 240lbs. ft.,just take a look at the owners manual if you can its all there. hills are no match for its 8cyl. it climbs them like it were just coasting along. I am overjoyed with mine, its what made me fall in love with cadillac, and its worth pumping a bit of money into, its cadillacs best engine behind the 4.9 and northstar which seem to be tied for 1st in that category, but the only thing the 4.9 has over the 4.5 is a few more cubic inches and some more power really. Good luck.
Automobile(s): 1985 Cadillac Sedan DeVille (83k miles)
Re: Requesting 4.5 89' Info
Hi there! Your 89 Fleetwood is mostly the same as my 89 Deville when it comes to everything, except interior of course. It has 155hp and a 4-speed transmission. The engine has only two injectors instead of eight like the 90 and newer models. I recommend ACDelco and Wix as brands for filters (air, oil, breather, fuel). I used to be a Quaker State 10w30 user. And while I might go back and try the higher mileage formula, I've currently switched to Valvoline MaxLife 10w30 (Wix oil filter) and have noticed an improvement in startup and idle. I recently spent $900 on converting the a/c to r134. While I didn't like the bill, since it's practically the trade-in value of the car, it was worth it. Make sure you get a radiator flush every 2-3 years, and get one now if it needs one. I think you'll enjoy the car. Make sure you've got a mechanic you can trust, and that knows the car, if you don't want to go to the dealership. Enjoy the car, from a time when Cadillac (not Lexus) meant "you have arrived"!
