strong waterflow
I have replaced the old leaky waterpump for a modern non leaky pump.
Now the water is pumped so strong into the radiator it is pouring out the overflow pipe,is there a simple solution to solve this problem? |

Re: strong waterflow
Make sure the coolant is below the radiator baffle.

Re: strong waterflow
Do you have a thermostat? fitting one will slow down the flow because of the restriction in the top hose. Alternatively, put a roofing nail in the overflow pipe.

Re: strong waterflow
It does not matter if the level of the coolant is low,it still pumps towards the overflow pipe.
I don't have a thermostat,i blocked the overflow but then the coolant is bubbling out of the filler neck/cap. |

Re: strong waterflow
Sounds like your rad is plugged up causing enough backpressure to push coolant out the overflow.

When the old waterpump was on there was no problem,the new pump has much more flow. I am thinking of creating some kind of restrictor in the upper hose or solder a copper plate into the rad so the direction of the flow will be bend off. |

Re: strong waterflow
Grind the fins down a little and drill a hole in each one...
Maybe your core was not done to factory specs Last edited by Mitch//pa; 01-20-2017 at 09:22 AM. |

Re: strong waterflow
The core was done by BLAAK RADIATOR SERVICE a weel known firm in the Netherlands who is specialized in vintage radiators,they even make a complete factory replica if you want to.http://www.blaak-radiateuren.nl/nl_NL/

Re: strong waterflow
I wonder if the baffle is missing in the radiator? Can someone post a picture of the radiator baffle? I think there is a good picture in ford service manaul!

Re: strong waterflow
If your core is not restricted, then you just have a velocity problem. You must be flowing over 40 gpm. Just put a restrictor plate of some sort in the upper hose.
Keep in mind that the only water the pump can pump is what it gets from the radiator. It can't pump too much, assuming you are not making bubbles of steam in the engine. Can you give us a picture of your set up? |

Re: strong waterflow
First look in the filler neck half throttle
Blue coolant in the filler neck 3/4 throttle Aluminum cup is a kind of restrictor i made but it flows into the cup and out of the overflow pipe. At the time of these pic's the engine was cold |

Re: strong waterflow
René, Before I installed a thermostat in my Town Sedan it had this restricter plate in the outlet. I took it out because I felt I didn't need both the thermostat and restricter.

Re: strong waterflow
I remember reading that the impeller fins are to large causing to much pressure ,I think you can grind them down and eliminate your problem

But before grinding the fins i want to try another solution,you can grind them down but not grind them up |
