What year motor will interchange with my 5.7 liter on a 1999 tahoe

The links lead me to believe there are interchangeable. In fact this page confirms the compatible models

1999 - 2006

No they are not. Unless the manufacturers have grouped together to make a line of cars than the engines of different manufacturers are not interchangeable. Some examples are the toyota matrix and the pontiac vibe parts are largely interchangeable as they are the same car with different branding. The chevy prism and the toyota tercell.

Most salvage yards should have interchange info for that. It depends on if you are getting a short block or the entire engine.

If your thinking of interchanging the head or short block then you can, depending on the cylinders, because the saturn sl2 2000 and 1999 were one of the few models ever to make a 1.9 liter DOHC. if you have a 1.8 DOHC then you should be fine with a 2001 or 2002

look at the cars vin# on the door panel. the 99 model it will tell you what month and year the car was made such as 06/1999 if the 1999 model was made from 06/99 not before but 06/99 and above the engines will fit. also check the bolt patterns on the transmissions and starter location on each motor to see if in the same locations. if all match,they will interchange. thank you for choosing fixya.com

I would run another fuel pressure test, I have had fuel pumps bad out of the box..:-(

I ~think~ the 1999 is the same as the 2000 (mine is a 2000 P71)

The 2000 CVPI (Crown Vic Police Interceptor) owners manual recommends the following:

Engine Oil - Motorcraft SAE 5W-30 Super Premium Motor Oil 5.0 quarts

Transmission Fluid - Motorcraft Mercon V ATF 13.9 quarts (fluids Mercon & Mercon V are NOT INTERCHANGEABLE, DO NOT MIX)

Fuel Tank - 19.0 gallons

Break Fluid - DOT 3


Rear Axle Lubricant - Motorcraft 80W-90 Premium Rear Axle Lubricant 3.75 pints (add 4 oz of Additive Friction Modifier C8AZ-19B546-A or equilavent meeting Ford Spec. EST-M2C118-A for complete refill of Traction-Lok Rear Axles)

Engine Data - 4.6L V8 Engine
Cubic Inches - 281
Required Fuel - 87 Octane
Firing Order - 1-3-7-2-6-5-4-8
Spark Plug Gap - 1.3-1.4 mm (0.052-0.056 inch)
Ignition System - Coil On Plug
Compression Ratio - 10.0:1

I hope this helps!

I believe in 97 they started the vortec 350 and they ran until 2001 not real sure but any salvage yard will know what years will fit. there are also different engine codes I think they are W and Z that will make alot of difference in the computer.

check your fuel pump pressure 90-00 has fuel pump problems check your fuel pressure and see if its up to spec's on that year, Hope that helps you out...
