الازاز الامامي كويس وحزام الامان جديد.

A natural Egyptian-style pronunciation is:

el-azāz el-amāmi kwayyis wi ḥizām el-amān gidīd

A few helpful notes:

• و is usually pronounced wi in Egyptian here, not wa as in MSA.
• ج in جديد is pronounced like a hard g in Egyptian, so gidīd.
• You may hear el- or il- for الـ depending on the speaker.

Because Arabic often leaves out the present-tense to be.

So:

• الازاز الامامي كويس = The front glass is good
• حزام الامان جديد = The seat belt is new

This is very normal in both Egyptian Arabic and MSA.
If you wanted a past meaning, then Arabic would use a verb such as كان.

Because adjectives usually come after the noun in Arabic.

So:

• الازاز الامامي = literally the glass the-front = the front glass
• حزام الامان is different, because that is not adjective + noun; it is a noun construction meaning safety belt / seat belt

This noun-first pattern is one of the most important word-order differences from English.

Because الامامي is an attributive adjective inside the noun phrase, while كويس is the predicate of the sentence.

Compare:

• الازاز الامامي = the front glass
  Here, الامامي directly describes الازاز, so it matches it in definiteness. Since الازاز is definite, الامامي is definite too.

• الازاز الامامي كويس = the front glass is good
  Here, كويس is not part of the noun phrase. It is the predicate, so it does not take الـ.

This is why Arabic has:

• the front glass = الازاز الامامي
• the front glass is good = الازاز الامامي كويس

الازاز in Egyptian Arabic means glass.

In this sentence, الازاز الامامي literally means the front glass. In a car-related context, it usually means:

• the windshield
• or the front window glass

The more formal MSA word would be الزجاج.

Yes, كويس is a very common Egyptian Arabic word meaning:

• good
• fine
• okay

It is much more natural in everyday Egyptian speech than جيد, which sounds more formal or MSA-like.

So in Egyptian:

• كويس = the normal everyday choice
• جيد = understandable, but more formal

In Egyptian Arabic, the conjunction و often sounds like wi or we in connected speech.

So:

• كويس وحزام الامان جديد
• is naturally read as kwayyis wi ḥizām el-amān gidīd

This is just a normal dialect feature. In MSA, learners are usually taught wa.

Arabic uses a different expression here.

حزام الامان literally means:

• belt of safety
• or safety belt

That is the normal Arabic equivalent of English seat belt.

So the translation is natural even though the words do not match English one-for-one.

It is an iḍāfa construction, often called a construct phrase.

Structure:

• حزام = belt
• الامان = safety

Together:

• حزام الامان = belt of safety / safety belt / seat belt

A key point about iḍāfa:

• the first noun usually does not take الـ
• the whole phrase can still be definite because the second noun is definite

So حزام الامان can naturally mean the seat belt in context.

Because they refer to singular masculine nouns:

• الازاز is treated as singular masculine
• حزام is singular masculine

So the predicates are:

• كويس = masculine singular
• جديد = masculine singular

If the noun were feminine, you would usually expect feminine forms, such as كويسة or جديدة, depending on the word and context.

Because informal Arabic writing often leaves out the hamza spelling details.

So in careful standard spelling, you would normally see:

• الأمامي
• الأمان

But in everyday typed Egyptian Arabic, people often write:

• الامامي
• الامان

Both are very common in casual writing, and learners should get used to seeing this.

It is clearly Egyptian Arabic in style.

The biggest clue is كويس, which is a very common Egyptian colloquial word. Also الازاز is dialectal wording; MSA would more likely use الزجاج.

A more MSA-like version would be something closer to:

الزجاج الأمامي جيد وحزام الأمان جديد

So the original sentence is best understood as everyday Egyptian Arabic.
