Engine Repair in South Windsor, CT | High Line Auto Service

From Minor Repairs to Complete Engine Replacement — We Handle It All.

When your engine has a problem, you need a shop you can trust to diagnose it accurately and repair it right. At High Line Auto Service, our ASE-certified technicians are equipped to handle engine repairs of every size and complexity — from a leaking head gasket to a complete engine replacement. No job is too big, too small, or too complicated for our team.

If another shop has told you the job is beyond what they can do, chances are we can handle it.

Full-Service Engine Repair

We perform a comprehensive range of engine repairs including:

• Head gasket replacement — one of the most complex engine repairs, done right with proper machining and torque procedures
• Timing chain and timing belt replacement — critical maintenance that prevents catastrophic engine damage if left too long
• Engine replacement — when repair isn't practical, we source and install quality replacement engines to get you back on the road
• Valve train repairs — camshafts, lifters, rocker arms, and everything in between
• Oil leaks and seals — rear main seals, valve cover gaskets, oil pan gaskets, and more
• Overheating diagnosis and repair — head gaskets, water pumps, thermostats, radiators, and cooling system failures
• Engine misfires and drivability issues — proper diagnostic testing to find the root cause, not just replace parts
• Internal engine repair — pistons, rings, bearings, and short block repairs



Whatever your engine needs, we have the tools, training, and experience to address it properly.

Diagnostics First — Always

Engine problems are rarely simple, and throwing parts at a problem wastes your money. At High Line Auto Service we take a diagnostic-first approach to every engine concern. Using advanced diagnostic equipment, we pinpoint exactly what's wrong before any repair begins — so you're only paying for what your vehicle actually needs. We'll explain what we found, what it means, and what your options are before we ever touch a wrench.

When Is Engine Replacement the Right Call?

Sometimes a repair estimate approaches or exceeds the cost of a quality replacement engine, and we'll always be honest with you about that. If replacement makes more financial sense than repair, we'll tell you — and we'll source a quality engine that gives your vehicle a new lease on life. We handle the entire process from sourcing to installation so you don't have to coordinate with multiple shops.
