The Winterizer installation is simply done by installing fittings at each of the drain ports and running hoses to a common mounting bracket, using quick couplings, filters and a reversible hand pump.
Always try to use a marine mechanic to install The Winterizer system or have them inspect your installation.

Remember that The Winterizer system will be a permanent installation.

Note: The engine block will store more water than the manifolds or coolers, so expect more pumping on those two fittings. Also both sides of the V block must be drained as they are not internally connected to drain.
