Nothing ruins your day faster than the engine of your car getting seized on the road. For vehicle owners, hearing the words “seized engine” is usually the worst-case scenario. It often means expensive repairs, long waiting times at the mechanic, or the realization that the car may need to be sold to a wrecker.
But what exactly is a seized engine, and how can you know if your car engine has seized? In this guide, our team at Adelaide A1 Auto Removals breaks down the warning signs of engine seizure and its causes. Additionally, we also explain if the engine of your vehicle is worth repairing and how you can still get top cash for your car, even if the engine won’t turn over.
What Exactly is a Seized Engine?
A seized engine essentially means the internal mechanics of your car engines have locked up perpetually. The metal components inside the engine, like pistons, bearings, and the crankshaft are stuck. The engine can no longer move as the crankshaft either comes to halt or does not spin properly.
Engine seizure usually happens because of friction. The lack of proper lubrication (oil) causes the metal parts to grind against each other, generating intense heat until they weld together or jam. Once an engine is seized the crankshaft cannot rotate, bringing the car to complete halt. Your car does not start after its engine is seized.
An important reminder: If you believe your engine is seizing or seized, do not try to force or jump start it. The continued attempts can cause catastrophic or huge damage to the starter motor of your car and other vital components.
5 Warning Signs Your Engine is Seized
Prevention is better than cure, detecting the problem in your engine early can sometimes save the car. Hence its essential you know the signs of engine seizure, check for the signs below to know if your car engine has seized
- The “Dead” Start: You turn the key, the lights come on, but you only hear a loud “clunk” sound The starter is trying to engage but the engine physically won’t turn, it means the car component is not moving
- Nasty Noises: Before the engine of your car dies completely the seizing engine usually makes a horrible grinding, knocking, or clunking sound. As internal parts scrape each other hard due to lack of engine oil.
- Burning Smells: If you smell burning rubber or hot metal coming from the engine bay of your car, it’s a sign of extreme friction and heat. The signs of friction caused by overheating is a warning sign your car engine is about to seize.
- Physical Resistance: If you (or a mechanic) try to manually turn the crankshaft with a wrench and it won’t budge, the engine may have seized. The immovability of the crankshaft is a sure-fire sign of engine seizure.
- Visible Leaks & Smoke: Puddles of oil under the car or blue/grey smoke coming from the exhaust or hood are major red flags that denote engine seizure. The engine seizure of engine often leads to damage in the oil pump
What are Some Common Causes of Engine Seizure?
Engines don’t usually seize without a reason, some of the most common culprits:
- Lack of proper lubrication: This is the key cause of engine seizure. Running out of oil, using the wrong type of engine oil, or having a broken oil pump in your car means the metal parts aren’t lubricated and the engine is facing constant pressure. Hence, proper lubrication is essential for car and engine health.
- Overheating: If your cooling system fails (leaking radiator, broken thermostat) while driving then the heat causes engine parts to expand and lock into place. Hence, it’s essential to know if your car is overheating constantly.
- Old, Sitting Cars: If a car sits in a driveway for years without running, moisture can rust the piston rings and the cylinder walls, seizing the engine.
- Hydrolock: If water gets into the air intake (like driving through deep floodwater), the engine tries to compress the water causing the engine to lock instantly.
- Coolant Contamination: if your vehicle coolant mixes with the engine oil, the lubrication in your car decreases and seizes the engine
How to prevent engine seizure?
In order to avoid the costly engine repair arising from a seizure, it is essential to keep it maintained. The two key measures to prevent engine seizure are
- Regular Oil Changes: Stick to the schedule of engine oil change mentioned in your car’s owner manual.
- Check Fluid Levels: Timely and Regularly check your dipstick and coolant reservoir to ensure there are no leakages. Additionally, also check if the coolant liquid needs a change to avoid overheating.
What to do when your engine is seized on the road ?
If you are stranded on the side of the road after a suspected engine seizure, do the following:
- Stop immediately. Do not try to drive.
- Shift to neutral and engage the handbrake.
- Call for a tow.
Once the car is at the mechanic’s, you need to face a really tough decision. Fixing a seized engine often requires a complete engine rebuild or replacement and for many older vehicles, the cost of the repair is higher than the value of the car itself.
