I am looking at trading in my 99 Blazer and getting a 2000 Tahoe. I
have a few questions though. I have noticed that some 2000 Tahoes
have the 5.7 L engine, and some have the 5.3 L engine. If the truck
has the 5.7 L engine is the rest of the truck also the "old" design?
Is it possible to have a "new" design truck with a 5.7 L engine?
I have noticed that the 99 Tahoes are a good bit cheaper than the 2000
Tahoes. Is the new style Tahoe worth it? I have heard that the old
style had a lot of head gasket problems, and transmission problems.
Have these issues been resolved with the new style? Does the new
style have any known problems?
Although gas mileage isn't a huge concern to me, I do like to know.
My Blazer gets 12 city, 19 highway. I'm guessing the Tahoe will get
slightly less on the highway, and about the same in the city. Is that
a good guess? Is there any difference in fuel economy between the old
and new styles?
Thanks in advance for your time,
No, if it has the 5.7 liter engine, it's the "old" design. This was
a "transition" year. Personally, I'd go for the "new" design.
Of course it has known problems. Front diff bearing failures, t/case
clutch pack failures (usually due to front diff failure), front axle seal
leaks, right rear brake inner pad premature wear (though for all intents
and purposes, it's normal), premature wear of park brake shoes (there
is a new design that has been released).
Old style truck never had "head gasket issues"....but plenty of
"intake gasket" issues. New style engine does not have a "wet"
manifold, so this issue has been eliminated. The only problem you
will face with the new engine is "piston slap" noise when cold, it's
fairly normal, and we have yet to actually replace an engine or
attempt a fix for this. As far as the transmissions, I don't think
the new style trucks really fixed much when it comes to the
transmissions. So you would want to follow a strict fluid
and filter change interval.
If a 2000 Tahoe has a 5.7 engine it is old style. The 5.3 is only used in
new style trucks in the U. S. There was not many problems with head
gaskets on the old style but huge problems with intake leaks and
injectors. Those issues have been handled on the new style. Some owners of
the new style complain of piston noise and slight oil comsumption. But fuel
milage is better. If I was to choose old or new style--- take the new , Far
Everything I've heard states that the newer 5.3 is a much better motor
than the older 5.7.
I ran a 5.3, and I'm now running a 6.0 - these new GenIII motors are
INCREDIBLE. They respond to mods so well, and are quite effient, stock.
I think you'll see 13/17 with the 5.3, and probably slightly worse
with the 5.7.
mine is a 1999 tahoe and not a problem yet(89000 miles)
I think the newer ones have MORE problems.
The intake manifold gasket developes water leaks on some, but i have no
problem and i think they solved that in 1998.
I would have to say, based on my experience...actually working
on the stupid things day in and day out...that the newer engines
have less problems. GM never solved the intake manifold gasket
problem on these engines.
Any thing with the 5.3 GM motor is a 1999 or up Pickup or
2000 & up Tahoe/Suburban.....
I own a late model (April 2000) 2000 5.3 4x4 EXT Cab Z71
Since a 2000 Tahoe arrived 1 year after, 99 5.3 Silverado...
any BIG engine bugs in the 2000 series Tahoe or Silverado
should be gone...
BIG difference Between the 2000 5.7 Tahoe and 2000 5.3 Tahoe
are thin front brake rotors on 5.7 (older) and thick
front brake rotors on the 5.3 (new) version...
Items that broke under warranty on my 2000 5.3 LT 4x4 Silverado
$2000 warranty of 6 years or 72,000 miles are:
Both the L & R heated mirrors (no heat), 4x4 push button switch,
fancy compass/Temp rear view mirror(electronics),
Left hand door (motor or gears?), All 4 Doors, rubber Moldings,
Both EXT Rear Suicide doors would not latch in cold weather.
had front steering pull to right(alignment would not
fix prob, but selecting Michelin LTX-AT tires & dumping
Pmetric Firestone Wilderness at 3800 miles did Wonders...
Had fan belt squeak (GoodYear Gatorback fixed that at 45000 mi),
Had steering shaft lubed twice to to eliminate clunk...
Had rear spline joint lubed twice for 'smooth takeoff'....
Spline joint lube frees up the entire rear Suspension!!
I used Mobil 1 oil after 5000 mi & have no leaks at 63,000 mi
