Is your car struggling to start in the cold? Here’s why. 🥶🔋
​When temperatures drop, two things happen at the same time:

1️⃣ Slower Chemical Reactions: Cold weather slows down the chemical process inside your battery, reducing its available cranking power.

2️⃣ Thicker Engine Oil: Cold engine oil turns thicker and harder to move, meaning your engine requires more power from the battery just to turn over.

​If your battery is already weak or aging, it won't have enough juice to handle the extra workload—leaving you stuck with a slow crank or a dead vehicle.
​Don't wait until you're stranded in the cold! At Diamond Diagnostics, we make battery testing effortless.

​⚡ Mobile Service Available — We come straight to your home or workplace!
⚡ Full battery and charging system diagnostics on the spot.

These rims were extremely oxidized and required a thorough rim buffing. Must have cost extra, right? WRONG!! At Diamond Diagnostics, we believe rim buffing should be included in the price of a mount & balance.

We buffed the rim and applied bead sealant to ensure an air tight seal using only the best products and equipment. We also only ever use non-abrasive sticky weights for wheel balancing to not cause any marks on the rims and prevent crorrosion from hapoening in the first place.

This vehicle was screaming loud due to the flex pipes being completely busted. On this design the flex pipes are one piece with the catalytic converters and are very expensive. Luckily, this customer found Diamond Diagnostics. We removed the assembly to cut and weld new flex pipes and reinstalled. Now she is sounding proper

We saved the customer hundreds if not THOUSANDS in repair cost.

Need exhaust work? No problem.
