SOURCE: oil pressure sending unit

Hi there;

Your looking foer the oil pressure sensor on the 2004 8.1L.
You will find it located directly behind the EGR valve threaded into the block just to the drivers side of the center bolt for the transmission to block connection.

Thanks
Farrout!

SOURCE: 2005 CHEVY +TRAIL BLAZER ABS AND BRAKE LIGHTS ON

When the ABS light is on when driving there is a problem in the anti lock brake system and you will need to have it tested to find out what the problem is. As long as the light is on the ABS has been shut off by the computer until it is repaired. There could be problems with one of the wheel speed sensors, wiring or the ABS pump. On some vehicles the red brake light will come on too.

SOURCE: M y radio stopped working on my 2004 trail blazer

The 2004 Trailblazer has two fuse panels, one in the under hood and one under the middle row seats. The radio fuse is marked RADIO fuse # 41 and is a 15 amp fuse located in the rear fuse panel. To access the rear fuse panel flip the seat behind the driver to the upright position, under it you can see the fuse panel and a diagram should be on the under side of the cover. 

Good luck and hope this helps.

SOURCE: 1991 chevy S10 blazer fluctuating oil pressure

I assume from the year it has high mileage. With mileage comes wear in these engine's bearings allowing oil pressure to drop because of the excess clearance between cam and bearings, also the crank and bearings. When the engine is hot and idling the oil is thinner and goes by the bearings quicker. If you have good oil pressure while driving, I'd leave it alone, maybe use a thicker oil or some lucas additive. My 89 does the same thing sometimes in the summer, but don't remember it doing it this summer. I use Mobil-1 and an AC Delco filter.

Where is the fuel filter located on my 2004 Chevy Trail Blazer? WE


On 05+ Trail Blazer, the fuel filter is integral with the fuel pump inside of the fuel tank. It is a non-serviceable part. On 02-04s, the filter is on the drivers side frame rail at about the B-pillar. If your trail Blazer is a late 04 which means that it was build close to the 05 Trail Blazer, you may have a non serviceable fuel filter. Good luck and check under your Trail Blazer or look at your manufactured date sticker on the door which would help you indicate if your 04 is a early Trail Blazer and you'll have the fuel filter on the inside frame rail under the driver's door.

Where is the pcv valve on the 2005 chevy trail blazer


It is located on top of the valve cover. Buy the new one and you will see what it looks like, then you will pull the hose off of it and put the new one on, 5-minutes at top to do this job.

Dear hispeed3,

If you haven't bought the part yet and are planning on replacing it ...i'd go to the auto parts store and ask them for the part location. They are usually glad to do this. I know Advanced Auto Parts does this for me.
