Verified Reviews for Auto Cooling System

“Really happy with MARCH and the service we received. I had another HVAC company come out and try to diagnose why my air-conditioner wasn’t working. They dismissed me several times and would not honour the warranty. I had MARCH come out and take a look and within 10 seconds, they knew exactly what the problem was and were able to fix it for me. Thankful for knowledgable and technicians.”

“These guys are incredible. They are always a pleasure to deal with we buy our filters from them and it's always a breeze dealing with them.

My moms furnace broke and they were able to come right away and help her out . They got the fix done within a small time frame and treated her very well ! Highly recommend these guys”

“My family and I have used M.A.R.C.H for the better part of 30 years and not once have they disappointed or been anything but transparent and professional. Amazing service and very reliable for our geothermal units. The only people we recommend!”

Common Causes of Cooling System Failure

Coolant leaks from cracked hoses, water pump seals, or radiator tanks
Failed thermostat stuck closed, preventing coolant flow
Water pump impeller failure reducing coolant circulation
Clogged radiator from internal corrosion or contaminated coolant
Blown head gasket allowing combustion gases into the cooling system
Electric cooling fan failure preventing airflow through the radiator at idle

Signs Your Cooling System Needs Service

Temperature gauge rising into the red zone or overheating warning
Visible coolant puddle (green, orange, or pink fluid) under the vehicle
Sweet antifreeze smell inside or outside the cabin
Heater blowing cold air when the engine is fully warmed up
Coolant reservoir consistently low or empty after recent fill-ups
Steam coming from under the hood while driving or parked

Auto Cooling System Tips

Never open a radiator cap when the engine is hot—pressurized steam can cause severe burns
Flush your coolant every 2 years or 50,000 km to prevent internal corrosion
Use the correct type of coolant specified by your manufacturer—don't mix different colors
Check your coolant level regularly, especially before long trips
A consistently dropping coolant level without visible leaks may indicate a head gasket issue
Replace rubber coolant hoses every 100,000 km as preventative maintenance—they deteriorate from the inside

Frequently Asked Questions

How much does a radiator replacement cost in Milton? +
Radiator replacement for most passenger vehicles costs $500-$1,000 including parts and labor. Trucks and SUVs can cost more due to larger radiators and additional components.
How often should coolant be flushed? +
Most manufacturers recommend a coolant flush every 2 to 5 years or 50,000 to 100,000 km. Long-life coolants may have extended intervals—check your owner's manual.
Can I just add water instead of coolant? +
Only in an emergency. Water alone doesn't provide freeze protection in Canadian winters, corrosion inhibitors, or the proper boiling point elevation. Always use the correct coolant mixture.
What should I do if my car overheats while driving? +
Immediately turn off the AC and turn the heater on full blast to help dissipate engine heat. Pull over safely, turn off the engine, and do not open the hood until it cools. Call for a tow to the nearest repair shop.
