Its not about the tyre but the sensors on the tyres.

Please I have a 2014 Toyota Avalon, I changed my left back tire, I bought Belgium tyres, the other 3 are brand new, the Belgium tyre is showing low tyre pressure on my dashboard but my mechanic say I should not worry, should I be bothered?

AntiChristian:
Have they sent her?

AntiChristian:
It's payback na! You don't want us to live in our country then we'll come live in yours and compete with you!

AntiChristian:
Are you the one that'll determine where he goes? It's enough for him to go anywhere that pleases him.

Yes, US is complicit in the destabilisation of most countries in the world! And that's a fact you can't contend with!

RyanAutomotive:
Good evening sir.

Thank you for the detailed explanation. Let’s go through this carefully before any major AC components are replaced unnecessarily.


🔎 Professional Diagnostic Insight

Vehicle: Toyota Corolla 2013

Your main symptom is very important:

• AC cools well in the morning
• Cooling becomes weak when the sun is hot

This pattern usually points to heat-load or system efficiency issues, not necessarily immediate compressor failure.

Let’s break down the technician’s points.


1️⃣ Compressor “Cannot Be Repaired” Claim

Your 2013 Corolla uses a variable displacement compressor.

Many technicians in Nigeria call it “automatic compressor” because it does not use a traditional magnetic clutch coil like older compressors.

However, this does NOT automatically mean the compressor must be replaced.

In many cases the issue may be:
• Weak compressor control valve
• Low refrigerant charge
• Condenser airflow issue
• High system pressure due to heat

A proper diagnosis should confirm pressure readings first before recommending compressor replacement.


2️⃣ AC Radiator (Condenser) Has Oil Deposits

Oil inside the condenser can happen when:
• A compressor had internal wear
• The system was previously opened
• Oil migrated through the system

However, if the car truly had recent service in the US as of October 2025, a heavily contaminated condenser would be unusual unless:

• There was a leak repair
• A compressor was previously replaced
• The system was improperly serviced

This needs confirmation before replacing parts.


⚠️ Important Observation

If the compressor was truly failing internally, you would typically notice:

• AC becoming weak both morning and afternoon
• Noise from compressor
• Metal contamination in the system
• Poor cooling at idle

Since your AC still cools well in the morning, it suggests the system still has some healthy compression.

That means the problem could instead be:

• Weak condenser cooling under high heat
• Cooling fan efficiency issue
• Slightly low refrigerant level
• Dirty condenser fins restricting airflow
• Expansion valve efficiency

These are far more common in Nigeria’s hot weather.


📌 What Should Be Checked First

Before replacing compressor or condenser, a proper AC diagnosis should include:

1️⃣ High and low pressure gauge test
2️⃣ Condenser airflow inspection (fan speed and airflow)
3️⃣ Refrigerant level verification
4️⃣ Temperature drop test at vents
5️⃣ Compressor control valve operation

Without these checks, replacing parts becomes trial and error.


🎯 Professional Take

Your technician may not necessarily be wrong, but the diagnosis sounds incomplete.

Replacing compressor + condenser together is a major repair, and it should only be recommended after pressure testing confirms compressor inefficiency or internal contamination.

Given the vehicle just entered Nigeria recently with a service history, it is reasonable to verify the diagnosis with proper AC system testing before spending money.


🏢 Ryan Automotive Limited Recommendation

Before replacing the compressor and condenser, ensure a proper AC pressure and performance diagnosis is carried out.

This will confirm whether the issue is truly compressor-related or simply cooling efficiency under heavy heat load, which is very common in Nigeria.


If you are in Lagos or able to bring the vehicle down, Ryan Automotive Limited carries out structured AC and vehicle diagnostics to avoid unnecessary part replacements.
