How to check the car engine when buying a used car

Updated: January 12, 2014
Inspecting a used car
When shopping for a used car, the condition of the engine, transmission and the car body are the most important. The fact that the car looks 'clean' and drives well doesn't mean much if its engine has a hidden problem or was poorly maintained by previous owners. Engine repairs are very expensive. Of course, it's difficult to evaluate the mechanical condition of the engine during a quick test drive, that is why we strongly recommend to have a used car properly inspected by a qualified mechanic before signing the contract. To help you be more informed, here are a few tips how to spot signs of engine problems or lack of maintenance when checking a used car.

Check used car service records
The service records are not always available, but it helps if the dealer can produce some proof that the vehicle was maintained regularly. If you can get access to the service records, look for oil changes and mileage records. It helps if you can verify that oil changes were done regularly. Depending on a manufacturer, the recommended oil change interval varies from 3,750 to 10,000 miles. If the vehicle was driven between oil changes for much longer intervals than recommended, the engine might be worn inside.
If a car has a timing belt (not all cars have it), see if there is any records that it was replaced. Typically, a timing belt needs to be replaced every 60,000 to 105,000 miles, depending on the vehicle. If it hasn't been replaced yet, it might cost you from $200 to $750 to have it done. Read more about a timing belt.

Have a look under the hood
When you are checking a used car at a dealer's lot, have a quick look under the hood before the test drive. It helps if you have a small flashlight. Make sure, the engine is off, the transmission is in "Park" and the parking brake is on. What you are looking for are the leaks, smell of burnt oil or antifreeze, signs poor quality repairs or lack of regular maintenance and 'racing' modifications.
If everything looks clean and shiny, it doesn't yet mean much, as car dealers often clean their used cars under the hood before showing them to potential buyers. Let's see some examples:

Signs of poor maintenance
Corroded car battery
If the battery looks like this, it's very unlikely that this vehicle has been maintained regularly.

Burnt oil smell under the hood
Shiny engine compartment
This Audi looks clean and shiny under the hood but we noticed a strong burn oil smell, which is a sign of possible problems.

Leaks
Coolant leak
This car runs fine, but a close inspection revealed the coolant leak from the radiator. As a minimum, this car requires a new radiator, but sometimes, a cracked radiator may be a sign of more serious problems. It's best to avoid used cars with this type of issues.
Engine from underneath
Watch out for oil leaks too. They may not be visible from above, but here is the trick - look underneath the car using your flashlight. Check the lower part of the engine and transmission. Everything has to be dry, like in this car. There might be a slight wetness which is not too bad, but there should be no leaks.

Low oil level
Low oil level on the dipstick
We checked the oil level in this car, and it's very low. Oil looks dirty too. This means that either this engine consumes oil or it was very long since the last oil change was done. In addition, the engine wears faster when low on oil. Normally the oil level should be close to "Full" mark.

Correct oil level on the dipstick
Engine oil in this car looks clean and the level is OK. It looks like the oil change has been done recently.

With the engine off, check under the oil cap
Oil cap
This test can tell a lot about the engine. If you aren't comfortable doing this test, leave it to your mechanic. With the engine off, remove the oil filler cap and look under it.

Checking under oil cap
For example, in the left photo, you can see there is a lot of black carbon deposits under the cap. The visible internal engine parts and the oil cap itself look very dirty too. Usually this is a sign of poor maintenance. In the right photo everything looks clean.

Watch out for performance mods
Engine performance mods
Be careful if a used car has some performance mods. If done right, the modifications can greatly improve the vehicle performance. However, poorly done engine mods can lead to many problems, especially if parts that were originally on the vehicle are no longer available. If the car has been modified, it's also likely that it has been raced or otherwise abused.

Cold start can reveal many hidden problems
The best way to catch hidden engine problems is to start it cold. To do this, it might be a good idea to come to the dealer a little earlier than your appointment time. First thing that this will reveal is how good is the battery, because if the battery is old, it might need to be boosted to start the car. Another thing to look at a cold start is the engine noises. If the engine rattles or makes other loud noises, it might be excessively worn or has some mechanical problems. Similarly, a blue smoke at a start-up means the engine is worn and it's best to look for another vehicle.

'Check Engine' light stays on
Check Engine light on the dash
After the car is started, all warning lights on the dash should come off. For example, in this car, the engine symbol that is known as "Check Engine" light remained on after it was started. This means that the engine computer detected some fault. It could be a minor issue, but it also could be a very expensive to repair problem. There is no way of knowing how serious is the problem until the car is properly diagnosed. Read more what "Check Engine" light means.

Smoke from exhaust
Blue smoke from the car exhaust
Here is another example: we started this car and noticed a blue-gray smoke from the exhaust. It smelled like burning oil too. A blue smoke means that the engine burns oil. Cars like this should be avoided.

Test drive
During the test drive, watch out for engine noises, vibrations, lack of power, or any other driveability issues. When started, the engine should run smooth, without shaking or hesitation. If you feel that the engine is bucking or stumbling when accelerated, there is a problem. The idle speed should be stable too. Test drive for as long as possible; sometimes problems may not be obvious during a short drive around the block. It's best to try the car in all modes: acceleration, deceleration, stop-and-go traffic, highway cruising. Watch out for the engine temperature on the dash. Once the engine is warmed up, the temperature gauge should stay somewhere around the middle of the scale.
Even if everything seems OK, we strongly recommend to have the used car properly inspected by an independent mechanic before buying.

In the year 2071, humanity has colonized several of the planets and moons of the solar system leaving the now uninhabitable surface of planet Earth behind. The Inter Solar System Police attempts to keep peace in the galaxy, aided in part by outlaw bounty hunters, referred to as "Cowboys". The ragtag team aboard the spaceship Bebop are two such individuals.
 
Buat keputusan kereta apa yang anda hendak beli... Boleh rujuk 8 LANGKAH DALAM MEMBUAT PEMILIHAN UNTUK MEMBELI KERETA sebelum membuat pemilihan.

02 Dapatkan harga atas jalan (on the road price) kenderaan tersebut. Ingat, harga solid dan metallic mempunyai harga yang berbeza. Sebagai contoh klik disini. Atau cara yang lain yang lebih baik, rujuk website rasmi pengeluar kenderaan untuk semak harga atas jalan tersebut.

03 Semak diskaun/rebat jika ada untuk kenderaan yang anda ingin beli. Kerana pada bahagian ini lah pelanggan selalu ditipu. Dinasihatkan untuk menyemak pada website rasmi pengeluar kenderaan... jngn terpedaya dengan diskaun/rebat yang luar biasa, selalunya lebih tinggi dari diskaun/rebat yang diumumkan oleh pengeluar kenderaan.

04 Minta jurujual kirakan bulanan kereta anda. Untuk pengetahuan anda, kiraan bulanan tersebut adalah anggaran jurujual sahaja. Tidak ada seorang jurujual pun yang boleh memberikan bulanan yang tepat kepada pelanggan kerana jumlah bulanan tersebut bergantung pada jumlah pinjaman, tahun pinjaman dan interest rate yang ditetapkan oleh bank.

05 Tanya jurujual, apakah hadiah atau free gift yang boleh diberi oleh jurujual. Disini pelanggan boleh nego dan membuat tawar menawar dengan jurujual. Minta la dengan berpada-berpada mengikut kemampuan jurujual. Kerana gift tersebut adalah daripada komisyen jurujual. Pendapatan jurujual adalah berdasarkan komisyen, jika pelanggan minta berlebihan, akan menganiaya jurujual. Disini la akan bermula segala macam penipuan dimana, jurujual akan cuba mendapatkan kembali wangnya yang telah dikikis oleh pelanggan. Kadangkala pelanggan yang telah berjumpa jurujual yang jujur, tetapi akhirnya mengubah jurujual tersebut kepada jurujual penipu kerana desakan pelanggan yang inginkan pelbagai hadiah. Apa yang penting anda mendapat kereta baru anda. Jangan hanya kerana mengejar hadiah bernilai 2-3 ratus tapi anda akhirnya hilang 3-4 ribu.

06 Setelah anda berpuas hati dengan maklumat diatas, anda boleh la menyediakan dokumen untuk membuat pinjaman. Berikut adalah senarai dokumen yang diperlukan untuk membuat pinjaman kereta di bank:.

Pekerja Kerajaan :

1. Salinan IC
2. Salinan Lesen
3. Payslip 3 bulan.
4. Bank Statement 3 bulan (bergantung kepada bank)
Pekerja Swasta :

1. Salinan IC
2. Salinan Lesen
3. Payslip 3 bulan. Kalau ada OT atau elaun sila bagi 6 bulan.
4. Bank Statement 3/6 bulan ikut payslip.
5. Penyata KWSP
Peniaga :

4. Dokumen Penjamin (rujuk kepada pekerja swasta /kerajaan)


07 Setelah dokumen tersebut telah diserahkan kepada jurujual, jurujual akan membuat permohonan pinjaman di bank bagi pihak anda. Setelah jurujual menyerahkan permohonan kepada pihak bank, pelanggan akan di temuramah (interview) oleh pihak bank. Jika jurujual ada mengajar cara menjawab, maka jawab la mengikut apa yang diajar oleh jurujual, kerana cara menjawab juga akan menentukan faktor kelulusan pinjaman.

08 Setelah ditemuramah, 2-7 hari selepas itu barulah keputusan oleh pihak bank akan dikeluarkan. Samada lulus atau gagal, ataupun kelulusan bersyarat. Jika telah lulus, semak jumlah pinjaman yang telah diluluskan. Harga atas jalan – jumlah pinjaman = jumlah bayaran pendahuluan yang perlu dikeluarkan. Contoh RM44,000 – RM40,000 (jumlah pinjaman) = RM4,000 bayaran pendahuluan.

09 Setelah anda berpuas hati dengan kelulusan tersebut, maka anda boleh la set kan masa untuk menandatangani perjanjian pinjaman. Minta jurujual aturkan temujanji anda dengan pihak bank.

10 Setelah perjanjian ditandatangani, maka anda boleh la menunggu pihak jurujual mendapatkan no chasis untuk anda. Tempoh menunggu bergantung kepada stok kenderaan tersebut. Setelah anda menerima no casis, anda boleh la membuat pembayaran wang pendahuluan jika ada. Jangan membuat pembayaran selagi anda tidak menerima no chasis. Minta jurujual sms atau text anda no chasis sebagai bukti. Ikutilah 3 langkah pembayaran ini untuk langkah keselamatan:

1. Pembayaran tunai (datang sendiri ke showroom)
2. Pemindahan wang melalui akaun (pastikan nama penerima adalah autorized dealaer/branch) bukan nama individu.
3. Pembayar melalui check atau bank draf (pastikan atas nama syarikat autorized dealer/branch) bukan nama individu.
11 Setelah pembayaran dibuat, anda boleh la menunggu kereta anda didaftarkan di JPJ. Setalah pendaftaran dibuat, 2-5 hari masa yang diperlukan untuk mendapatkan geran serta cukai jalan daripada jpj. Tempoh tersebut adalah bergantung pada situasi.

12 Sebaik sahaja jurujual menghubungi anda bahawa geran dan cukai jalan diterima, anda boleh la menentukan masa dan lokasi untuk mengambil kereta.

13 Periksa kereta anda semasa mengambil kereta. Setelah anda berpuas hati dengan keadaan kereta anda, tuntut lah hadiah yang dijanjikan. Kemudian tandatangan borang penyerahan kereta dan bawa la pulang kereta baru anda.
