Nice Concours! I thought the Concours had the 300HP L37, I guess I'm wrong, all '94s had the LD8 Northstar. I had a 96 SLS with the LD8 powertrain, that thing got some sweet highway MPG, with the 3.11 gears and all. My STS with L37/3.71 gears isn't good on gas at all.
Go to cadillacforums.com and read up in the technical archive, lots of stuff you need to know in there. Basics - get the coolant changed NOW, trans fluid exchange to Dexron VI (have GM dealer do it), new plugs/wires, brake and power steering fluid.
Rockauto.com and cadillacforums.com are your friends when you have a Northstar powered Caddy. Enjoy!
Thanks. The more I drive it the more I like it.
I've been visiting the cadillacforums as well.
Did a little more reading up on it.
It's actually 270hp and 300 lb*ft of torque. LD8 engine (8th digit in vin Y), 4T80-E Tranny.
0-60 in 7.8 sec. Quarter mile, sec/mph 15.8/91.0
Fuel economy,EPA, city/hwy., mpg 16/25
The only options it doesn't have is a CD player, moon roof and chrome rims.
Build date was 12/93 for mine. The late 94 Concours came with the L37 4.6 engine and the Non Concours Deville had a 4.9 L26 engine.
Lucky for me, a full service has already been done on it. All fluids changed, plugs, wires, all filters and a new battery was installed before I got it @ 108K. It came with the paperwork. Even have the original owners manual in a leather case including the calculator. It runs and drives great. The previous owner took great care of it it seems.
I took it to my mechanic who confirmed everything was done. We put it up on the lift and found some oil dripping off the bottom of the oil pan. Turns out the filter was a little loose. It was due for it's 3K oil change anyway so we changed the oil/filter (7.5qts!) then cleaned up the underneath. No oil drips since.
The brakes look new and no marks on the rotors. All tires have 85%+ tread remaining and are wearing evenly.
I'm a happy camper so far.
