Optomistic thinking..
I've been reading up on coolant flushes, citric acid flush, the right MB Dex coolant, and all that fun stuff getting ready to clean out Betsy's cooling system before summer and collage finally set in.
Here's what i've come to.. - Citric acid can either make coolant passages "Food grade", or eat holes in old radiators like mine.. -Flushing with water will never remove all sediment, possibly not even most of it. - Green coolant and my aluminum head need a divorce. I have the right coolant in the garage waiting. But here's my idea of a "better flush" Water, in a low pressure environment, can be considered uncompressible. By low pressure I mean garden hose pressure, maybe small pump pressure. This comes into play because the water will act more like a solid to reverberate pulsations throughout the entire cooling system. go ahead, read on :] Water flowing through a cooling system will indeed displace the old coolant and prepare for new, but will build up sediment and junk in low-flow and small areas (radiator, heater core, low lying places) Regular flowing water allows the chance for sediments to settle because the water flows in a more "linear" fashion, my idea sprouts from this. Pulsating water does not flow in such a linear way and will more violently agitate and flow sediment out of the cooling system. By pulsating I mean water pressure applied in full-on, and full-off states, very quickly. I have a solenoid valve, and I can set up a power transistor to oscillate the valve open and close at around 10-20 hertz for pulsation. I plan to connect the water supply to the heater core supply, is that a good place? Is this a decent idea, or am I wasting time? |

This is a motor that you can practically cool with the heater core. Did you ever have coolant temps over the full open temp of the thermostat with the radiator full?

About to flush my system as well - what about this? As a plumber and a plumbing salesman in past lives, I have known about Drain King for years.

I has seen 100C twice. Today I removed the radiator and cleaned the fins out along with the A/C condenser. The fins on both were about clogged with bugs and other gunk and now look brand new. I used a foam condenser fin cleaner on both. This gave it a huge drop in temps. I also took out my aftermarket electric fan and reinstalled the original fan. Now Betsy's runnin' at 80C all the time. It's not so much a heat problem, I just want to clean out the pond water looking crap and do it right |

Dead on, it's basically plunging a cooling system toilet instead of trying to slowly wash the junk out of it. |
