A radiator Question

[mjs2011]

Al,

Thanks for posting up those threads. Very informative. I think I will stay away from using corrosive chemicals to flush the radiator. I did a simple back flush with water and pressures it up and blew some chunks out. I have a new thermostat on order and plan to see if those things will help. If not, I may have to look into getting a champion radiator like you mentioned.

CHRIS I REPLACED RADIATOR W/ALUM. ONE I THINK THE THERMOSTAT WAS 190 DEGREE I PUT BACK IN SO IS THAT WHY IM RUNNING WARMER NOW, OR IS IT CAVITATION?...NOT YELLING JUST FORGOT TO TURN CAP LOCKS OFF....REPLACED WATER PUMP,FAN CLUTCH TOO

Did you see what thermostat came out that you put back in. If it was not a factory thermostat you really need to replace it. No after market thermostats ahve been proven to work much at all. Many of them will over heat our engines because they can't pass enough coolt thru them. Now after posting this I do know of one member here thats been running an after market thermostat and had no issues with ti. He has remained silant about it toobecause he does not want the heat from others on here but told me this.. When he chooses to out himself he will do it with said thersomstat as proof. I do tip my hat to said member..

That helps tremendously.... adding that to the parts list on the blackboard.

I checked bigger dummys coolant temp today with my ir temp gun and he has a guage issue. His needle was sitting on the "A" but his actual coolant temp was only 205

WRONG.....................

I should have known that the electric one was the correct one as it controls computer..duh
Now got to go 20 miles to get right temp. sender & electrical gauge.

What I ended up doing was taking out the radiator and backflushing it. I did this until I had clean water coming out the bottom (actually the top of the radiator, but it was set upside down). I then duct taped the hose into the radiator and pressured it up several times with my hand, and each time I did this, I held until the cap released pressure, then let my hand go. A bunch of chunks blew out and I noticed the flow out of the opening slowly increased, from about 1/3 of the diameter of the opening to nearly the whole opening.

Once pressuring was no longer producing chunks, I sealed up both openings of the radiator, and poured in two bottles of gunk radiator cleaner, and flipped the radiator around for about a half hour. When I dumped it, i got a dirty green liquid, so I am guessing that a few more plugged cores in the radiator opened up. Another backflush and pressure up produced a bunch more dirty coolant and chunks. I did this until I again had clean water flowing through.

Then I replaced the thermostat with a new one. About 30 bucks from Ford, and the gasket was 12. I then verified that my heating issues were resolved, which they are to an extent, though I still want to get an aluminum radiator some day. It is now sitting with Fleet Charge coolant precharged with SCA additive.

Which reminds me. Does anyone know where I can get SCA test strips. I asked the guy at NAPA, and he had no idea what I was talking about.

I asked about sca test strips at NAPA, They said they have not been able to get them for about a year. Didn't know why.

They are not trying hard enough to get them. I bought 2 new bottles of strips from napa last week. Made by wix

Fleetguard Coolant Analysis Test Kit CC2602A

I searched "sca test strips" on Amazon.com. Small kit is under $10, the bigger one is under 50.
