GM released the 4.6 Cadillac Northstar Engine in the 1993 Cadillac Allante. Since then just about every Cadillac vehicle has had used them as their power plant. As of now the Northstar has been all but phased out except for the DTS. The Northstar engines since the beginning have had several inherent design flaws.
1. Main saddles get out of round over time and result in low oil pressure.
2. Cylinder head bolts pull out of block due to coolant deteriorating threads and heat.
3. Blown head gaskets.
4. Overheating.
5. Oil leaks.
Promar Precision Engines have been pioneers in remanufacturing the 4.6 DOHC 32 Valve Cadillac Northstar Engines. We were one of the first remanufactures in the country to offer remanufactured 4.6 Northstar engines to the public, even before oversize pistons were available. We have made multiple enhancements and longevity increasing upgrades to the original O.E. design. With impeccable machine work, and our proven high quality engines backed up by our trend setting 3 year unlimited mileage warranty, Promar once again has all of our competitors chasing after our success. We offer all makes, models, and years of the 4.6 Northstar engine.
Every high quality 4.6 Cadillac Northstar Engine that we build comes with:
Proper Block Strengthening techniques to ensure no more blown head gaskets (and without having to use the overpriced and unnecessary cylinder head studs)
Line boring with custom main bearings to eliminate out of round main bearing bores and any low oil pressure problems!!!
