redreeper where did you use the vacuum tool? The hose from the overflow going into the radiator? Seems like a silly question figured I would ask a pro

Seems like a silly question figured I would ask a pro Mine came with a big rubber plug, I removed coolant cap and shoved the plug in there then pulled the vacuum & coolant out through there, then put new coolant in same way. Worked great & took less than 30 mins to change thermostat & coolant. |

Mind sharing where you got your vacuum from? Went to Oreilys out here and all they had was crappy little hand pumps which I don't think will have enough auction to get the junk at the bottom out. You buy it online or at a parts store?

You buy it online or at a parts store? Bought mine online. I'll look & see if I still have the link for it. |

Post #15 is a dead link. There are several electric pumps that could work, but I need to know the cooling system flow rate. I'd love to try an electric pump |

Another problem you may encounter is pumping water to fast thru the radiator and not efficiently removing the heat from the water/coolant. If you push water to fast thru a radiator it will not cool the water and will still over heat. I have seen this before when I worked at ARA air conditioning. As some engines without a thermostat that's been removed from the system will over heat for the same reason. Not enough heat transfer to the cooling fins and bag, it over heats and you got coolant flowing like crazy. It'll leave you standing there scratching your head when you know more is better. So be careful adding extra pumps to move more water. Have some way to control the amount of coolant your moving.  |

I think the thermostat will act as an orifice that prevents too much flow, but it gets to a point where the temperature and pressure behind it could make it cavitate. If I can match or slightly increase the flow rate through the system I should be able to help along or totally eliminate the mechanical pump. If the rate is too low the engine will overheat, if too high it will increase pressure, pushing the electric pump too high on the curve and deadhead it - overheat the pump motor. I'm working this thing too hard - cant find a rate close enough to the stock pump rate for me to feel good. Eliminating the mechanical pump would certainly destroy the engine if (when) the electric pump kicks the bucket, but putting in another restriction (a failed electric pump) would kill it if the mechanical pump had to push through it. Relocating the radiator to the back is the holy grail...
