UView 069-3577 Combustion Leak Tester Block Tester Kit

The UView 069-3577 is a combustion leak tester (block tester) designed to detect exhaust gases in engine coolant. This diagnostic tool helps technicians quickly identify head gasket failures, cracked cylinder heads, or cracked engine blocks by detecting the presence of combustion gases in the cooling system — without requiring coolant removal or disassembly.

Key Features:

• Detects combustion gases in the cooling system for fast head gasket leak diagnosis
• Chemical indicator fluid changes color in the presence of exhaust gases (hydrocarbons)
• Works on gasoline and diesel engines
• Non-invasive test — no need to drain coolant
• Durable construction for repeated professional use
• Includes tester body and chemical test fluid

This block tester is an essential tool for any automotive repair shop or serious DIY mechanic. It provides a reliable, chemical-based detection method to confirm or rule out internal combustion leaks quickly and accurately, saving time over more involved pressure or teardown diagnostics.
