Question about 2001 Pontiac Grand Prix

1 Answer

I have a 01 grand prix with a 3.1 and its bogging!

I have a 01 grand prix with a 3.1 and a few days ago I replaced the coolant temp sensor and then it started running hot and then started bogging. So today I changed the plugs and the wires and it still does the same thing. I was told that it might be the o2 sensor or the fuel filter but I want more advise. Any ideas?

Did you get all the air out of the coolant system?

Why would you change the plugs and wires?

Better yet, don't believe what your told,unless it comes from a professional,who just diagnosed your issues,correctly.

Please tell me why a fuel filter,would cause an overheating issue. Even after 45 years ,I 'am still willing to learn .

What was the original complaint?

Where is the engine coolant temp sensor located on a 2004 grand prix gt

On the 3.8 liter the coolant temp sensor is right below the the thermostat in the intake manifold on the drivers side of the engine.

The thermostat is under the housing that is bolted to the intake plenum that the upper hose is attached to.

My check engine light is on, and today my temperature gauge stopped working and we have replaced the engine coolant sensor and the connector and temperature gauge still not working. PLEASE HELP

Could be the thermostat. I know nothing about cars but I noticed my 2000 Grand Prix temp gauge was not going to the normal level. My wife drives this car so I didn't notice it for a month or so. Eventually the Engine light came on. Took it to Autozone and the code came back as P0180... (1) low coolant (2) bad thermostat (3) enginge fuel temp sensor. They used a code reader that was about the size of an Ipod nano.

Coolant was okay, so took it to my mechanic. His netbook sized computer showed it was the Thermostat. He reset the codes and the temp guage went back to normal. Was short on $40 for the fix at the time, so I parked the car and promised to bring it back in 3 days. Went out and checked the car a day later at 25 degrees outside without starting the car... gauge still sitting at the normal level. No question it's the thermostat. That car will not be driven again until T.stat is fixed in 2 days.

possible IAC dirty, throttle plate dirty, Coolant temp sensor stuck and flooding conditions occur.

Coolant temp below thermostat regulating temp

more than likely the thermostat has stuck open. Or opening to soon not allowing the car to reach normal operating temperature. I would start by replacing the thermostat. Clearing the code and running a drive cycle and see if the code comes back. if the code does not return problem solved. if it does return replace the coolant temp sensor.

We just installed a new coolent temp switch in my 94 grand prix se 3.1 and the temp guage doesnt rise what could be the problem?

Why I was asking is this engine uses 2 coolant sensors the one for the computer to operate fans and adjust fuel delivery is a 3 wire sensor on the intake outlet area and the one for the temp gauge should be on the head and a 2wire sensor.IT has been awhile since I worked on a 3.1L I think this info is correct.

Replaced thermostat and MAF sensor but temp still all over the place and car shakes in idol

Radiator may also be partially plugged. This usually becomes evident mostly in the spring, when ambient temps start to rise. When in motion, air flowing through unplugged radiator is sufficient to keep temp down, but at idle, fan can't pull enough air by itself. Since outside air isn't as cold, heat transfer is incomplete.
I'm sure someone out there will argue about my method, but I disconnect lower hose and block off the radiator lower connection, then do the same at the top. I use one container of CLR and pour directly into radiator (if you don't have a fill cap, use upper hose opening instead of blocking it) slowly pour in water 'till it's full. Leave for an hour then drain, use a garden hose to blow water through from top, out through bottom till it runs clear Seal off outside of hose to get pressure into radiator, wrap rag around it), then re-connect hoses, re-fill with coolant. (engine running heat full on).Generally this will give you most if not all flow restored.
