Extreme temperatures can affect the way your car performs and jeopardise your safety, regardless of which end of the spectrum you’re on. Some of these small changes in the environment can have serious effects on your vehicle, so we’re taking a closer look at the way hot and cold weather impacts transmissions. MV Auto is here to help you avoid car trouble in every season.
How Cold Weather Affects Cars
Icy evenings and frosty mornings can have adverse effects on your car. Some problem with transmissions are completely unique to winter and others are simply worsened by cold weather.
When they are cold, some of your car parts may contract and get smaller. This can lead to loose components, premature wear and tear, and leaks when seals start to shrink.
Changes in Transmission Fluid
In the cold, transmission fluid changes its viscosity and gets thicker. When the transmission falls below zero degrees, the transmission fluid becomes too thick and fails to lubricate the parts that it should.
The computer in your car may delay your overdrive function until the transmission reaches an appropriate temperature. This can impact how comfortable your driving experience is and put pressure on your gears.
Excess Water in the Transmission
It’s never a good thing to find water in your transmission. In cold weather, it can be even more dangerous. If the water freezes in your transmission, it will expand and cause damage to the valve body and case. Cracks in your transmission can’t be repaired and will require a replacement.
Increased Difficulty when Driving
It’s important to adjust how you drive in winter, especially on those freezing mornings. A transmission with additional pressure on it may have difficulty adapting to changes in conditions, so drive slowly, minimise shifting, and avoid excessive idling to help it perform the best it can.
How Hot Weather Affects Cars
Warm weather, hot roads and dry air can take their toll on your car. In the hot summer months in Australia, there are certain things to take into consideration when you’re driving.
Checking Your Tyre Pressure
This is something that should be done all year ‘round; however, it’s even more important during summer. Hot pavement can cause major problems for tyres and even lead to a blowout, especially if your tyres aren’t inflated properly. Make sure you replace your tyres before summer if they are looking worn out.
Shortened Battery Life
Hot weather can shorten your battery’s life, especially if you’re taking long summer road trips! We always recommend that car owners carry a set of jumper cables in case they get stranded, and get a mechanic to check your battery terminals for corrosion.
Changing the Engine Oil
Hot engines need additional lubrication, so make sure you’re ahead of your oil changes before summer hits. Oil starts to deteriorate over time, but this can be avoided if you stay up to date on your log book servicing.
Low Coolant Levels
Keep an eye on your car’s temperature gauge in summer to prevent it from overheating. Low coolant levels can destroy your engine, and this is even more prevalent during the summer months.
Servicing Your Car Will Minimise These Issues
The good news is there’s one sure-fire way to prevent your car from developing problems in both summer and winter. Regular log book servicing gives your mechanic the chance to inspect and repair parts in your car before the issues can get any worse.
