Frequently Asked Questions

What coolant should I refill with?

Use the correct type and mix for your system and top it off after bleeding; do not run plain water long term as it corrodes the alloy.

Why did my old hose fail?

Age hardens or swells the rubber so it cracks or collapses; heat and pressure cycles do it in even without a leak.

Can a collapsing hose cause overheating?

Yes - a hose that sucks flat under suction chokes coolant flow and overheats the engine, so replace a soft hose promptly.
