الموتور والكاوتش جاهزين للفحص الفني.

It is not said in the present tense.

Arabic often makes present-tense sentences without a verb like is/are. So:

الموتور والكاوتش جاهزين
literally = the engine and the tires ready

That naturally means the engine and the tires are ready.

If you wanted the past, you would usually add a verb, for example:

كانوا جاهزين = they were ready

Because the subject has two things joined by و (and):

الموتور والكاوتش = the engine and the tires

In Egyptian Arabic, when two nouns are joined this way, the predicate is normally put in the plural. So:

• جاهز = ready (masculine singular)
• جاهزين = ready (masculine plural)

So جاهزين matches the engine and the tires together.

This is a good question because Arabic learners often expect a dual whenever there are exactly two things.

In Egyptian Arabic, the plural is very natural here after two nouns joined by و. So:

الموتور والكاوتش جاهزين
is the normal colloquial pattern.

In more formal or Standard Arabic, you may see dual agreement more often in similar situations, but in Egyptian speech جاهزين is what you should expect.

In Egyptian Arabic, كاوتش is often used as a collective word for a vehicle’s tires/rubber, even if English would translate it as tires.

So:

• الكاوتش can mean the tires as a set
• كاوتشات can be used if you want to talk about individual tires more explicitly

This is very common in Egyptian speech.

They are common loanwords in Egyptian Arabic.

• الموتور = from motor
• الكاوتش = a borrowed word used for rubber / tires

These are very normal in everyday Egyptian Arabic.

If you wanted more formal Standard Arabic vocabulary, you would more likely see:

• المحرّك for engine
• الإطارات for tires

So this sentence sounds Egyptian and natural, especially in everyday or semi-technical speech.

Because it is made of:

• لـ = for
• الفحص = the inspection

When لـ comes before a word starting with الـ, they attach in writing:

ل + الفحص = للفحص

So للفحص الفني means:

for the technical inspection

In pronunciation, this is usually something like lel-faḥs or lil-faḥs in connected speech.

Because adjectives in Arabic usually match the noun in definiteness.

Here:

• الفحص = the inspection (definite)
• so the adjective must also be definite:
• الفني = the technical

Together:

الفحص الفني = the technical inspection

Compare:

• فحص فني = a technical inspection
• الفحص الفني = the technical inspection

A simple learner-friendly pronunciation would be:

el-motor wel-kawtsh gahzeen lel-faḥs el-fanni

A few useful notes:

• ج in Egyptian Arabic is usually pronounced like g in go
  • so جاهزين sounds like gahzeen, not jahzeen
• و here sounds like we / wel
• الفني is roughly el-fanni

You do not need a perfect transliteration, but this is a good practical approximation.

It is best understood as Egyptian Arabic with a formal/technical phrase at the end.

Why?

• الموتور and الكاوتش are strongly associated with everyday Egyptian usage
• الفحص الفني sounds more official or bureaucratic, the kind of phrase you might hear in licensing or inspection contexts

A more Standard Arabic version would be something like:

المحرّك والإطارات جاهزان للفحص الفني

So the original sentence feels very natural for Egyptian usage, especially in real-life practical contexts.

Because both nouns are definite:

• الموتور = the engine
• الكاوتش = the tires

In Arabic, when two definite nouns are joined by و, each one normally keeps its own definite article.

So:

الموتور والكاوتش = the engine and the tires

If you removed الـ from the second noun, it would change the meaning:

• الموتور والكاوتش = the engine and the tires
• الموتور وكاوتش = the engine and tires / some tires

So the repeated الـ is important.

جاهز means ready, prepared, or set.

In this sentence, it means the engine and tires are in a suitable condition for inspection.

Forms you may want to know:

• جاهز = ready (masculine singular)
• جاهزة = ready (feminine singular)
• جاهزين = ready (plural / common colloquial form here)

So جاهزين للفحص الفني means they are ready for the technical inspection.
