SOURCE: 2002 Pontiac Grand Prix Thermostat

as you face the engine the thermostat bell is on the right (drivers side) Follow the radiatoe hose. Remove the two bolts and raise the bell still attatched to the hose. the thermostat is there with the rubber seal. You can gently pry the thermostat out with a screwdriver or something similar. Put in new thermostat be sure it is the same as the old one, and then replace or change the seal (be sure it is the smae size and thickness as the old one as I got the wrong size from Napa) Then replace the bell, and tighten, but not over tighten. I hope this helps!

Under the passenger side of the dashboard is a carpeted cover you'll need to remove. Once that's out of the way you'll see the blower motor on the RH side and just to the left of it right next to the frontwall is the blower motor resistor held in by two screws.
Here's a picture of the old design (right) versus the new design (left).

How do i reset my pontiac 2002 grand prix in orer to pass emissions?


A new cat what was the original code. Usually you need to drive the car for a while after changing a battery (1/2 hour to an hour) on the road so that the cpu as all the data it needs before going for etest especially the new etest machine. The place that change the cat is it the same place that is doing the emission test?

Readiness monitors wont reset


You have 8 I/M or Emission Monitors
3 continuous
5 that have to run

They should run clear after 10 or 15 miles of driving
IF,ALL problems have been resolved

The Evap Monitor will only run every few days

Any person or repair shop HAS TO Road Test with scan tool
until the monitors run,except evap,BEFORE,BEFORE,Your given
the car back

It is NOT,NOT your job to run monitors or drive cycles

You would have no idea what they are, or how to perform
them,some shops don't ,as they have no data base or care
to look up that info

Bottom Line

Your car was not properly diagnosed or repaired (YET)

No Codes on a code reader, is not the same as using professional
tools & enhanced data & other data, to find a problem

Don't need codes present to see or find things that are not right

My 2002 pontiac grand am won't pass emissions because the CAT and o2S monitors are not ready...how long do I need to drive before they reset. I had the test 2 weeks ago and have driven it about 250 miles,...


You did not need to drive at all

The Monitor will run & if there is nothing
out of range to fix, your good to go

There is no drive cycle,if that is what your asking

You should have checked for codes two weeks ago,
& diagnosed the codes & made the required repairs

What is the drive cycle after changing the catalytic converter on a 2001 pontiac grand prix


there is no drive cycle, just get in and go. But if youre asking for the cycle on the readiness monitor for the CAT. it will take several drive cycles for that monitor to run to see if the new CAT. passes or not.

My 2002 Grand Prix GT 3.8L Won't pass emissions. Testing center's scanner says car was recently worked on and that the mileage driven since is not enough to recycle check engine light. The ck eng. light...


Nope, you just need more miles. When the car's computer has been disconnected from power (such as when the battery is unhooked), it'll set what are called "readiness codes" when power is reapplied. It takes a certain number of miles to clear these - some cars require 50 miles, some 100 miles, and some (such as some Isuzu models) need very specific drive cycles to clear them. Once the requisite number of miles have been driven without issues, the readiness codes will extinguish and your car should pass.
