Miracle Paint and a Leaking Radiator

Total KUDOs to the makers of "Miracle Paint"!!!! I went through 2 separate kits of plastic repair stuff on my radiator at the radiator neck. The last person to replace the hose cracked the radiator by pulling side-to-side on the hose. Now I have a seam crack 3" down the side of the plastic housing, and at the inside of the elbow. I decided to try the "Miracle Paint" with the standard fiberglass cloth. - put one coat of paint on the crack + 1" either side of the crack, - allow it to sit 15 minutes, - apply the fiberglass cloth, press it down so that it is tight against the crack and surrounding area, and - apply another coat of "Miracle Paint". - Let it dry overnight - Apply a 3rd and 4th coat of paint and let this dry 12-24 hours between coats.

Cruise control erratic

I have a 90 300d. My cruise control is being very erratic. I will click set, and then it accelerates probably at least 5 mph faster than i set it and then it shuts it off and then back on, and then back off and on etc. Has any body had this happened? I am lost at where to start. I have a alldata manual on it but its not much help. Is there some sort of adjustment with it? Thanks Jerritt

87' 300TD NO A/C

Hello Everyone, I just bought a 87' 300TD. The a/c is not working. I'm a ASE certified master tech but I have no experience with Mercedes. The climate control seems to be working OK. THe fan speed changes with the temp settings, the air blows from the correct ducts when swithched which usually indicates no vacuum leaks or sevo problems. But the A/C compressor clutch does not engage. I checked the high and low pressure switches on the high side a/c line near the sight glass and they are not getting any power to them so jumping them will not help. I've read that the a/c control cutout relay could be bad, but I don't like throwing new parts at a problem without verifying with a test 1st. So can you tell me how to properly diagnos this ?? Thanks in advance for any help. Art D

Liquid Block Sealer - Is it worth the hype?

First of all, it's not December 31, 1969, but instead is April 9, 2008. I have a 1990 300TE that had a heater hose break, and the dumb fool poured cold water into the radiator bottle. Now I have oil in the water (though no water in the oil!). Advance Auto sells this bottle of green fluid that GUARANTEES to fix leaks in head gaskets, cracked blocks, valve cover gaskets, etc. that is added to water. The big hitch is that the car must be able to idle for 50 minutes while the stuff does it's thing. One thing I found out; a cracked block is not conducive to idling more than a couple of minutes - much less 50 minutes (no wonder it's guaranteed to work if you follow the directions to the letter).

When to replace Accumulator Cells on 1987 300TDT?

I have had a 1987 300TDT diesel wagon (w124) for one year. It has 185,000 miles. I don't know whether replacing the Accumulator Cells would improve the quality of the ride, since I don't know what it should feel like. The rear end doesn't sag, and the self-leveling system works. Do the Accumulator Cells degrade the quality of the ride gradually, over time, or do they just break and you know it immediately, due to a bouncy ride? thanks
