The key to summer driving is keeping the engine cool. We're going to talk about the radiator and coolant soon, but first you need to check the hoses and belts. The hoses connected to the radiator help pump coolant to and from the engine block, and the belts run the fan that helps cool the system further. If the hoses crack or the belts snap, the radiator will quickly overheat, leaving you stranded.
Check hoses for cracks, leaks and loose connections. Hoses should be firm, never soft and malleable. Hoses suffer from a slow deterioration process called electrochemical degradation (ECD) that eats away at rubber hose material from the inside. The most vulnerable parts of the hose are those nearest to clamps where the hose connects to the radiator or the engine.
Belts can also be visually checked for cracks and damage. Take note if the belt looks excessively slick or smooth. Remove the belt to make sure that the material hasn't started separating into different layers. Experts say the risk of belt failure rises dramatically after 36,000 miles (57,936 kilometers).

Change Oil and Oil Filter
Oil is the lifeblood of your car. It keeps hardworking engine parts running clean, smooth and cool. Most owner's manuals suggest that you change your oil and oil filter every 7,500 miles (12,070 kilometers). Oil change specialists suggest every 3,000 miles (4,828 kilometers) or three months. The fact is, most of us do a lot of heavy driving during the summer when an engine is more likely to overheat. So at least check your oil before you head out on that road trip with the family.
To check your oil, let your car run for a few minutes, then park it on a level surface and shut off the engine. Open the hood and locate the oil dipstick. You're looking for two things here: the level of oil and how the oil looks. If you're low on oil, you can either add another quart or simply change the oil completely. The oil should look brownish yellow and clean on the stick. If the oil is a dark color or there's a lot of dirt and grime in it, then you definitely need an oil change and oil filter replacement.

Run your AC in winter
To keep your car’s air-conditioning system fit for the next warm season,
run it a few times throughout the winter. This will prevent moving
parts in the compressor from seizing. Also, circulating the refrigerant
will help keep the seals soft and pliant.

Clean your engine
There are several reasons to wash your engine at least every year or
two. A clean engine will run cooler than a dirty one. You’ll be more apt
to tackle routine belt and hose checks and the like if you know you
won’t get covered with grime every time you do so. A clean engine will
also make it much easier to spot leaks and to service components.
Remember to protect sensitive engine components — including the air
intake, distributor, and electrical parts — with plastic bags before
getting started. Use dishwashing liquid or other grease-cutting
detergents and a bristle brush to scrub engine and components surfaces.
Rinse thoroughly. Heavy-duty engine cleaning products are available at
automotive parts stores. Follow the directions carefully. You may also
have your engine professionally steam cleaned.

Beware the wet thumb
If you top off your tires at a service station, check to see if there’s
moisture coming from the air pump. Simply depress the pin inside the
inflator valve with your thumbnail. If your thumb gets wet, advise the
station manager that his tanks need to be drained and go to a different
station. Moisture, trapped inside a tire, can cause pressure variations
and corrode rims.

Maintain proper inflation
Under-inflated tires are a tire salesman’s best friend. They create
excessive heat and stress that can lead to tire failure. If you want to
get every last mile out of your tires, get yourself a tire pressure
gauge and use it at least once a month (more in hot weather) to keep
your tires inflated to the recommendation in the vehicle’s owner’s
manual. Check tires when they are cold (driven for less than one mile)
for an accurate reading.

Wax to protect your car’s paint job
No way around it! Waxing your car is work. But it’s satisfying work
that will help keep your car looking new. Car wax preserves paint by
slowing oxidation and forming a barrier against bird droppings, sap, and
pollution. Plus driving a nice shiny car is just plain fun.
Here’s what to do to ensure the maximum in protection:
Here’s what to do to ensure the maximum in protection:
- Liquid and spray waxes are tempting to use — they make the car shiny with less work than rubbing in paste wax. But there’s still no beating paste wax for the hardest, longest-lasting finish. Look for paste with a high carnauba wax content.
- Apply a thin, even coat of wax to the car’s surfaces with a damp sponge. Avoid applying too much, or it will be difficult to remove and some residue will inevitably mar your finish.
- To avoid fine scratches, use a clean, soft cotton or microfiber cloth to remove wax once it has dried.
- Apply an extra coat of wax to the nose and hood. The wax film in these areas wears away quickly.

Keep leather from drying out and cracking
Leather cars seats are durable and don’t require a lot of maintenance.
After a few years, however, the seats can become soiled. Use a leather
cleaner to remove dirt and stains.Then apply a leather protectant
formulated for pigmented or top-coated grain leather (the leather used
for most leather car upholstery). Protectants will resist stains and
make the upholstery easier to clean in the future. Choose a protectant
that includes conditioners to keep your leather supple.

Fix bad weatherstripping immediately
If your weatherstripping is letting rainwater leak into the interior of
your car, take a look at it and decide if you can repair it or if it
needs to be replaced. Small leaks can be handled with brush-on seam
sealers. Resecure loose sections, not otherwise damaged, with trim
adhesive. Torn sections may be repaired with special caulking available
at auto parts stores. You may also be able to extend the life of
worn-but-intact sections by inserting foam rods, available at automotive
stores, into the hollow section of the weatherstripping. If you decide
to replace entire sections of gasket, don’t simply buy generic stuff
such as you’d use around the house. Buy a product that matches your
car’s original weatherstripping — it’s available in a wide variety of
profiles from dealerships and automotive mail-order catalogues.
