Hello everyone,
I am having a bit of a problem, I need to replace my Coolant Temperature Sensor on my 1997 Pontiac Grand Prix SE 3800. However, there's a bracket bolted in my way and I do not know how to maneuver around it. Is there anyway I can get to it or do I have to take the bracket off?
Thanks,

Re: Coolant Temperature Sensor
You do not have to remove any brackets to replace the coolant temperature sensor on your Grand Prix. Normally, you can get a wrench on it through the opening towards the driver's side of the car. If you need some extra space, you can remove the upper hose/thermostat housing and/or the engine harness located above it. This isn't usually necessary, but can make it more open.
Once you get the sensor loose, you can turn it out the rest of the way with your fingers.

Okay, the engine harness is what I was referring to, so hopefully I will be able to get to it without doing all of that. I'll try to remove the upper hose because I can't get to it regularly.ProTech wrote:You do not have to remove any brackets to replace the coolant temperature sensor on your Grand Prix.

Try a deep socket 19 with a swivel head...im working on it now and thats what i am trying next. Its in a spit that makes it a pain...tried all other options and nothing
Re: 3800 Coolant Temperature Sensor Replacement
And that first response was just dead wrong! With the 3800 engine it is much more difficult due to the placement of the sensor. You can barely get the deep socket 19 around the sensor then when u do you cannot turn the handle because it hits the bracket. Its gotta be the worst placement for something so easy to repair...
