Icon7 My first Truck

Hi Everyone,

I just bought my first truck and its a 2002 Ford Ranger 3.0! I'm excited to get it on the road. Any tips and advice you have for me is much appreciated!

Also, what mods have you guys done to make it look more awesome. I'm thinking of doing lifts, getting bigger tires, etc. Share what you have with me. Here's a pic of the Ranger

Nice looking truck

Ranger's are good, reliable trucks, but every engine has it's little issues

3.0l engine did have one flaw over the years, the cam synchronizer bushing would start to wear out and cause a high pitch squeal almost like a fan belt slipping, they last about 80-100k and need to be replace.
Not an expensive part just takes a bit of labor to swap it out
Good read here: Ford Ranger 3.0L Camshaft Position Sensor

If you hear the noise you need to change this sooner than later, the cam synchronizer runs the oil pump so..........don't want that to stop

2002 3.0l is also getting near the years of the exhaust valve seat issues.
Ford's TSB just covered '04-'06 but it did effect earlier 3.0ls

FORD: 2004-2006 Ranger

Some 2004-2006 Rangers 3.0L-2V "Vulcan"vehicles may exhibit:
- Malfunction indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P0300-P0306 and P0316
- Rough running at various RPM
- Rough idle
- Misfire

This may be due to an engine exhaust valve seat recession causing a loss of compression. Refer to the following Service Procedure to diagnose exhaust valve seat recession.
1. Perform a power balance rest to clarify if a cylinder is misfiring. Identify and keep record of any cylinder that has a concern.

2. Perform a manual compression test with the spark plugs removed to locate any cylinder that may have low compression. Refer to the appropriate Workshop Manual, Engine System, General Information, 303-00.

3. If no low compression is found per shop manual instructions, proceed with normal misfire diagnostics per the Powertrain Controls/Emissions Diagnosis (PC/ED) Manual for the appropriate model year.

4. If low compression is found and it is a cylinder that had a misfire on power balance, perform a leakdown test to determine the source of leakage that may be causing the low compression. Refer to the appropriate Workshop Manual, Engine System, General Information, 303-00.

5. If low compression is found in a cylinder that did not have a misfire detected then proceed with normal base engine diagnostics per the Workshop Manual, Engine System, General Information, 303-00.6.

If the exhaust valve is identified as the source, replace both cylinder heads with the newly released service cylinder heads. Refer to the appropriate Workshop Manual, Section 301-01A.
