Re: Engine temp rises when I get to cruise speed
So the saga continues...I replaced the Speedway water pumps last night with a pair modified by Skip Haney. The impellers are definitely different. There was nothing wrong with the impellers on the speedway pumps as they're only about 2 years old. No pitting
Because of the rain, I won't be able to test drive today |

Re: Engine temp rises when I get to cruise speed
Test ride today and there's no difference. 73* outside today and the gauge read 205* at its highest.
Forgot to mention I went back to propylene glycol at a 50/50 ratio Last edited by jrvariel48; 10-08-2022 at 05:39 AM. Reason: add to post |

Re: Engine temp rises when I get to cruise speed
You need a radiator with a bigger core to dissipate more heat. God only knows you've tried everything else and then some. Hopefully Brassworks will meet you in the middle and get the right solution to your problem.
Best of luck, B&S |

Re: Engine temp rises when I get to cruise speed
That's what I'm hoping for. You're right, I tried everything EXCEPT mounting a second fan which is what Brassworks recommended. I told Lee that wasn't an option for me. I don't like running one fan, but I don't have a choice because of the blower, pullies, etc. I'll email him this week.

If your temperatures are rising to 205 on the highway and Lee says that a second fan is going to lower them, then I'm not buying that for one minute. No offense to Lee, but fans (any dang fans) are not helping you at 55 mph. My goal would be for not higher than about 190 going down the highway - unless it was 100 degrees out and I was pulling some huge grade. Best of luck, hope you get things sorted out. B&S |

Re: Engine temp rises when I get to cruise speed
One of my friends had an issue where the flat head ran around 200 degrees. But it never got any hotter or lost water, it did have a catch can, He put a piece of tape over the temp gauge and enjoyed the heat while driving in the winter.

The outside temp was 43* degrees today when I went for my ride. It didn't go over 180* even without the fan on the entire 1 hour ride! |

Re: Engine temp rises when I get to cruise speed
If you can afford a supercharger, I think you should be able to afford the correct radiator.

Re: Engine temp rises when I get to cruise speed
With 43 degrees outside temp the engine should be no where's near 180 degrees running temp it should be a lot lower. I realize you were able to finally drive an hour without the fan on the entire time but there's a still HUGE problem with that cooling system. I'm thinking RADIATOR is the problem.

Re: Engine temp rises when I get to cruise speed
Oh heck that was only three months ago
Now just think if the radiator was changed at the beginning of all this how many fun miles would have been driven since then. .

I think the OP has no intention of ever changing out his radiator. He's having too much fun keeping this thread going on forever.

Re: Engine temp rises when I get to cruise speed
Ron, the driving is always fun and never a burden. I just had to focus on my temp but that didn't stop me from driving!

Re: Engine temp rises when I get to cruise speed
(1) flathead rule of thumb/safe operating temperature; ambient air temp in degrees + 100
(2) your current powerplant is producing more BTUs than your radiator can reject. |
