Engine Repair in Northeast Edmonton
An engine problem rarely fixes itself, and it usually gets more expensive the longer it runs. At Just Auto on 66 Street NW, we repair engine-related issues across many makes and models, from oil and coolant leaks to overheating, misfires and drivability problems. We find the cause first, then show you what we found and give you an estimate. Nothing is done without your OK.
Signs you need it
- Oil spots under the vehicle, or the oil level dropping between changes
- Coolant leaks, a sweet smell, or the temperature gauge climbing
- The engine overheats, or steam comes from under the hood
- A misfire, rough idle, shaking or hesitation when you accelerate
- Loss of power, stalling or hard starting
- A check engine light, especially if it is flashing
How it works at Just Auto
- Book a diagnostic visit online or call (780) 340-0258. Tell us what the engine is doing and when it started.
- We find the cause. Engine symptoms often share causes, so we diagnose before replacing anything. See [vehicle diagnostics](/service/vehicle-diagnostics).
- We show you what we found and give you an estimate for the repair.
- Nothing is repaired until you approve it.
- We do the work you approved, and tell you when your vehicle is ready.
Leaks
Oil and coolant leaks start small. A gasket or seal that weeps a little can become a steady drip, and an engine that runs low on oil or coolant can be damaged quickly. Note the colour and where the spot is under the vehicle. Dark brown or black is usually engine oil. Green, orange or pink is usually coolant. Have any steady leak checked, and keep an eye on the levels until it is fixed. Our fluid services cover the coolant itself.
Overheating
An engine that runs hot can be low on coolant, have a leak, a failing thermostat, water pump or radiator, or a cooling fan that is not working. Overheating can warp parts and damage the head gasket, so it is not something to drive through. If the temperature gauge climbs into the red or a temperature warning comes on, pull over when it is safe, turn the engine off, and do not open a hot radiator cap. Call us before driving further.
Misfires and drivability
A misfire feels like a stumble, shake or loss of power, and often turns the check engine light on. Common causes include worn spark plugs, a failing ignition coil, a vacuum leak or a fuel problem. A flashing check engine light usually means a severe misfire, which can overheat and damage the catalytic converter, so ease off and have it checked soon.
Cold weather
Edmonton winters are hard on engines. Cold starts put the most wear on an engine, and thick oil, a weak battery and short trips add up. Plugging in your block heater on the coldest nights, using the oil grade your manufacturer specifies and keeping up with oil changes all help. See our oil change page for the oil side of winter.
Finding us
Just Auto is at 12208 66 Street NW, on the south side of Yellowhead Trail at 66 Street. It is a short drive from Montrose, Bellevue, Highlands, Belvedere, Balwin and the rest of northeast Edmonton.

Questions
Is it safe to drive with an oil leak?
A small seep is usually not an emergency, but keep checking the oil level and top it up. If the oil level drops quickly, the oil pressure light comes on, or oil is dripping onto hot parts, stop driving and call us.
Why does my engine misfire only when it is cold?
Some faults show up only at certain temperatures, such as a weak ignition coil or a vacuum leak that seals once the engine warms up. Tell us when it happens; it helps us find it.
Do you work on every engine?
We repair engine-related issues across many makes and models. Call or book with your vehicle's year, make and model, and we will tell you whether it is work we can take on.
Will you start repairs without asking?
No. We find the cause, explain it and give you an estimate first. Nothing is repaired until you approve it.
