Love the room...watch out for manifold

1999 Pontiac Montana 4dr Ext Minivan
Bought this van when we started having a family...it's a perfect family vehicle. The EXT offers seating for 8 AND room for cargo. Have used it like a truck (with seats out) and of course as the family vanster on extended trips... have really been pleased with everything - except chronic problems with the intake manifold gasket. Original plastic part couldn't be torqued properly... extreme temp changes in northern climates led to expansion/contraction which caused leaks. Replaced manifold gasket at 47,000 and again at 66,000 mi (thankfully before antifreeze could gum up engine). GM has re-engineered the part (and assure this chronic problem has been fixed)... the second repair GM paid 80%.)
Very roomy, great ride, have gotten as high as 29 mpg!! The ultimate family vehicle.
Original manifold gasket design is faulty...re-engineered part includes metal stamping to allow proper torque to be applied - hopefully no more leaks!! If you have a problem...be persistent in your complaints to GM - They paided 80% of my repair bill.
