How to detect a hidden radiator leak in Suzuki Khyber?

Sometimes radiator leaks in a Suzuki Khyber aren’t easily visible — there may be no puddles, yet you keep losing coolant. These are called “hidden” o r “internal” leaks. Here’s how to detect them:

🔍 Steps to Detect a Hidden Radiator Leak:
Check for White Smoke from Exhaust:

If coolant is leaking into the engine head gasket issue, it will create white smoke from the exhaust.

This usually also comes with a sweet smell and loss of power.

Look for Moisture Around Radiator Fins o r Under the Hood:

Run the engine and check for steam, moisture, o r white residue near the radiator, pipes, o r thermostat housing.

Use a Pressure Tester:

A radiator pressure tester pumps air into the system and helps identify small leaks.

Mechanics in Pakistan often use this simple tool to check for leaks in older cars like Khyber.

Check the Oil Dipstick:

If the oil looks milky o r creamy, coolant may be leaking into the engine — again, a possible head gasket o r internal leak.

Check Under the Carpet Cabin Heater Leak:

Some Khybers have a cabin heater connected to the radiator system. If it leaks, you may notice wet carpets o r a foggy windshield inside the car.

🔧 What to Do if You Find a Leak:
If it’s a minor external leak, it can often be repaired with sealants o r by replacing a hose.

Internal leaks head gasket, heater core are more serious and require a mechanic’s attention.

Tip:
Ask your local radiator shop to do a coolant pressure test and a leak-down test. These are affordable and commonly done in workshops across Pakistan.
