Frequently Asked Questions About Engine Replacement | Green Mountain Auto World, Denver CO
​
When do I need an engine replacement?
You may need an engine replacement if your vehicle is experiencing severe engine damage, excessive wear, or catastrophic failure. Common signs include knocking or tapping noises, excessive smoke, coolant or oil leaks, low compression, or repeated engine overheating. Our ASE-certified technicians can assess your engine and recommend the best solution.
Can a damaged engine be repaired instead of replaced?
In some cases, minor engine problems can be repaired with rebuilds, part replacements, or tune-ups. However, if the engine has irreversible damage to the block, cylinders, or internal components, a full engine replacement is the safest and most reliable solution.
How long does an engine replacement take?
The timeline for engine replacement depends on the vehicle and type of engine, but most replacements take 1–3 days. Our technicians ensure precise removal, installation, calibration, and post-installation testing to restore full performance and reliability.
