Problem

Rubber seal on aluminum cooling tube has failed. Coolant is leaking into back area of engine timing cover and out of hole.

Solution

Install an AGA collapsible cooling tube. We have designed a tube and seals that can be installed (by experienced tech) in under 10 hours.

Benefit

A potential $11,000 – $13,000 repair job is now achieved for less than $3,000. Additionally, the repair can be completed same-day compared to 2-3 weeks.
