Engine Repair Services

We offer full engine repair services in Maryland Heights so your vehicle keeps running strong. Our certified techs have the skills and gear to tackle any engine issue—fast and efficiently.


Engine Diagnostic

We use modern diagnostic tools to pinpoint what’s wrong with your engine. First, we listen to your concerns and check how the engine’s performing.

The diagnostic service includes:


  • Computer scan for error codes
  • Visual inspection of engine components
  • Test drive to verify symptoms
  • Compression and leak-down testing if needed


After diagnosing, we’ll explain what we found in plain language. You’ll get a clear report showing what needs attention and what it’ll cost.

We never push repairs you don’t need. If your check engine light is on or you hear something odd, bring your vehicle by—catching problems early usually saves a lot of money.


Oil Leak Repair

Oil leaks can wreck your engine and even become a safety issue. We track down and fix leaks at the source to protect your car. We start with a detailed inspection to spot every leak. Special dyes and UV lights help us find even the tiniest ones. We’ll swap out the bad gaskets or seals using quality parts. All surfaces get cleaned thoroughly before we install new gaskets, which helps prevent future leaks.


Oil Pan Replacement

The oil pan holds your engine’s oil and can get damaged by road debris or rust. A busted oil pan puts your whole engine at risk. We’ll remove the old pan, clean up the sealing surfaces, and install a new pan with a fresh gasket. While we're there, we check the oil pickup tube and screen for any issues.


Timing Belt Replacement

Your timing belt keeps the crankshaft and camshaft moving in sync. If it snaps, your engine could be toast in seconds. Most cars need a new timing belt every 60,000 to 100,000 miles. When we do this service, we also replace the water pump, tensioners, pulleys, seals, and coolant.


Coolant Service

Your engine’s cooling system stops overheating and fights off corrosion. Regular coolant service helps your engine last longer and keeps repairs cheaper. Our full coolant service includes draining old coolant, flushing the system, inspecting hoses and connections, pressure testing for leaks, and refilling coolant.


Radiator Repair

Your radiator moves heat from the coolant out to the air. If it’s damaged, you risk overheating and engine failure.

We handle radiator services like:


  • Leak repair
  • Radiator flushing
  • Full replacement
  • Fan and shroud fixes
  • Pressure testing


Engine Replacement

Sometimes, repairs just don't make sense anymore. If that's the case, swapping out the engine could actually save you money in the long run. We can set you up with either a remanufactured engine or a used one. It's your call, and we'll walk you through the options.
