This will sound counter intertuiative but increasing the fan size can actually make the problem worse as hot engine air is pulled back to the front of the radiator and a viscous circle starts. A member of our club confirmed this situation exists in an actual test. As mentioned in the attached memo from Geoff Healey the first place to look is the radiator baffles. Their job is to stop engine compartment air from coming to the front of the radiator at low speeds. The baffles are hard to see and even harder to work on.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>After reading the Geoff Healey memo I have added additional baffles to each side of he radiator. This is the first place to look before fans, pumps, pulleys, etc. Unless the incoming air temperature to the radiator is kept under about 120 deg F nothing else will help. If ambient air is always drawn into the radiator it will push out the hot air that accumulates under the hood.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Harold<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:healeys@autox.team.net">Don via Healeys</a><br><b>Sent: </b>Friday, June 4, 2021 8:17 AM<br><b>To: </b><a href="mailto:gonnagitcha90@hotmail.com">Richard Collins</a><br><b>Cc: </b><a href="mailto:Healeys@autox.team.net">Healeys@autox.team.net</a><br><b>Subject: </b>Re: [Healeys] air ducting kit</p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>This is my latest attempt on solving my vapor lock problems.

So the introduction of the shovel from the frame to the radiator produces a hurricane velocity up and through the radiator on the BJ8. That alone should be sufficient to cool water. But it does not move the water very fast through the engine back to the radiator, especially under low rpms. So I have introduced an electric water pump (Aussie idea, as it does get hot down under) to keep the flow of water through the radiator to the engine through the water pump and back to the radiator. it adds 150 liter per minute to the trickle produced by the mechanical pump. I fact one of the listeners commented that he could turn off the fan and just keep the water pump operating on highway speeds. It was easy to install using existing hoses cut in half going from the bottom of the radiator up to the inlet on the engine, and 2 x 1/8<sup>th</sup> diameter holes in the thermostat to allow the water to flow during engine warm up.</span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:148.8pt'><span style='font-size:18.0pt;font-family:"Arial",sans-serif'> </span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:148.8pt'><span style='font-size:18.0pt;font-family:"Arial",sans-serif'>After a run, I keep both the fan/EWP operating for a few min after the engine shut down which helps to reduce flashing of the hot water.
