White residue found inside radiator

[Impala Steve]

Hi,
I've got a 58 Impala with a 348 motor and have been having high engine temperature readings. I decided to try a product called Thermocure by Evaporust after doing 2 treatments for heavy rust in the engine, has anyone experienced a white residue inside their radiator or the intake manifold? What brand of radiator flush fluid do you recommend to get rid of the white residue? It seems to come off when I scrape it off-it like plumbers putty in texture when mixed with water it feels like toothpaste.

I would take the radiator out and get it cleaned by a radiator shop. Don't forget the heater core if you use it.

Thanks, appreciate it.

Just be ready for a big bill if you take your radiator to be cleaned! Those places (the ones I've dealt with anyway) will be sure to blow holes in your core so they can get themselves a "re-core" job! It doesn't take much to destroy a radiator when they are old. A few pounds too much and

And the last re-core I got a price on was $550 for a 2 core radiator!!!!!!!!!!! I told them where to stick that job.

You got screwed Bob. I had a shop make me a 4 core and move the inlet hose fitting using my tanks. I didn't like the way GM had the inlet and outlet directly below/above each other. Around $400 5 years ago. I did get a discount through the business.

I didn't get screwed, I took my radiator home. I ended up taking a used radiator I had and swapping the brackets from my other. Savings=$550 C'ching!

Calcium build up from hardwater use. Use radiator boil out solution from auto store. It it EDTA which is caustic. If its not to bad use half the bottle and boil system out. Then flush and rinse with garden hose after engine is cool. Repeat with other half of bottle. Then fill with 50/50 DISTILLED WATER and ANTIFREEZE.

Many years ago, I took my original, 3 Core 409 Radiator, to a shop near me.$ 400-$ 500.00 for a Recore. I told him, I could buy a Desert Cooler 4-Core, for less than $ 350.00. He smiled and said "I Know" That was his final answer. I bought one, from Show Cars.

I remember paying $125.00 for a re-core for my 68 Impala (2 core) I still have it in fact! That would be about 1988. How times have changed.

I don't think $15.00 is going to do it Phil.

 

[wristpin]

Would you give me $250 for it Phil?
