GMC Terrain StabiliTrak and Traction Control Lights On Together: Causes and Fix
GMC Terrain StabiliTrak and traction control warning lights illuminating simultaneously almost always indicate a wheel speed sensor fault, a failed steering angle sensor, a throttle body that has accumulated enough carbon to disrupt the electronic throttle control signal, or a low battery voltage condition that corrupts the stability control module’s input data. On the 2010 […]
How Much Does a Coolant Flush Cost: Jiffy Lube vs Independent Shop
A coolant flush costs $70 to $120 at Jiffy Lube and similar quick-service chains and $80 to $150 at an independent shop, but the price is the least important factor in this service: what matters far more is whether the provider is performing an actual flush (machine-exchanged), a drain-and-refill, or just a top-off, and whether […]
How Much Does Fuel Pump Replacement Cost: Parts and Labor
Fuel pump replacement costs $250 to $650 total at an independent shop for most passenger vehicles, with parts accounting for $80 to $300 and labor accounting for $100 to $250, though prices vary significantly by vehicle because in-tank fuel pump access ranges from a simple access panel under the rear seat to a complete fuel […]
How Much Does It Cost to Diagnose a Check Engine Light at a Dealership
A check engine light diagnosis costs $100 to $180 at a dealership and $75 to $150 at an independent shop, with the diagnostic fee typically applied toward the repair cost if you authorize the work at the same location on the same visit.

How Much Does It Cost to Fix a Blown Head Gasket at a Shop
Fixing a blown head gasket at a shop costs $800 to $1,500 for a 4-cylinder engine and $1,200 to $2,800 for a V6 or V8, with the final bill determined by whether the cylinder head needs resurfacing, whether torque-to-yield head bolts must be replaced, and whether any secondary damage from overheating has occurred. These price […]
How Much Does It Cost to Replace All Four Shocks and Struts
Replacing all four shocks and struts costs $600 to $1,800 at an independent shop and $900 to $2,800 at a dealership for most passenger vehicles, with the wide range driven by whether the vehicle uses simple bolt-on shocks (lower cost) or MacPherson struts that require spring compression equipment and strut mount replacement (higher cost), and […]
How to Check If a Catalytic Converter Is Clogged: DIY Test
The most reliable DIY test for a clogged catalytic converter is a vacuum gauge test at idle and at 2,500 RPM: a healthy converter allows exhaust to flow freely and the vacuum reading holds steady or increases slightly at higher RPM, while a clogged converter creates backpressure that causes the vacuum reading to drop progressively […]
How to Check If a Head Gasket Is Blown Without a Mechanic
Yes, you can check for a blown head gasket at home without a mechanic using four tests: the combustion gas leak test, the oil dipstick and reservoir inspection, the compression test, and the cooling system pressure hold test. No single test is definitive on its own, but two or more positive results from these tests […]
How to Check If a PCV Valve Is Bad: Symptoms, Oil Consumption, and Tests
A bad PCV valve causes oil consumption by either sticking open (creating excessive crankcase vacuum that pulls oil mist past piston rings and valve stem seals into the combustion chamber) or sticking closed (allowing pressure to build in the crankcase that forces oil past gaskets and seals to the outside of the engine). These are […]
How to Check Transmission Fluid Without a Dipstick: Ford Focus
The Ford Focus with the PowerShift dual-clutch automatic transmission (2012 to 2016, using the DPS6 unit) has no dipstick: the correct procedure to check or verify fluid level requires lifting the vehicle, locating the fill and level plug on the driver’s side of the transmission housing, and confirming that fluid is present at the bottom […]
