Re: [MBZ] Mystery Water leak W123 300D (Peter Merle)
Talking about coolant leaks, I was fiddling under the bonnet of my 190E the other day because the breather hose came off and was making a wee bit of a mess. While I was fixing that I noticed a bit of coolant had dribbled out of the top radiator hose, when I tried to pull the top hose off the neck snapped off. Anyway all fixed now with a Nissen radiator which cost about 60% of the price of the Behr unit. However the Nissen does not have the handy drain plug the Behr has but you can't have everything. I looked at getting the old radiator fixed but it had a couple of pin holes in the core so would have cost the same to fix as a new Nissen. Bloody Behr only lasting 22 years, what a piece of junk. - Original Message - From: B Dike [EMAIL PROTECTED] To: mercedes@okiebenz.com Sent: Friday, March 09, 2007 4:24 PM Subject: Re: [MBZ] Mystery Water leak W123 300D (Peter Merle) Peter, The miniscule leak you describe is likely due to an old weeping coolant hose.

Those plastic tank rads cannot be repaired, anyway -- the aluminum flange fails when you attempt to re-crimp it. Believe me, I tried with the Volvo. Don't use green coolant, it seems to make that plastic go brittle faster, amongst other nasty things. At least it broke in the drive cold (ditto for the Volvo) -- else it takes the head with it, as my sister did in her Volvo turbo wagon. Peter
Re: [MBZ] Mystery Water leak W123 300D (Peter Merle)
Don't think the cheaper Nissen ones can be but the Behr units are repairable once. It depends on the skill of the repairer and the place I went to for advice does a lot of Behr radiators, they also do a lot of work for the local stealerships. And good on ya for owning up to having owned a Volvo, it's all part of the healing process:-) - Original Message - From: Peter Frederick [EMAIL PROTECTED] To: Mercedes Discussion List mercedes@okiebenz.com Sent: Saturday, March 10, 2007 10:27 AM Subject: Re: [MBZ] Mystery Water leak W123 300D (Peter Merle) Those plastic tank rads cannot be repaired, anyway -- the aluminum flange fails when you attempt to re-crimp it.

Re: [MBZ] Mystery Water leak W123 300D (Peter Merle)
The Volvo 740/760/940/960 series were great cars, so were the 240s. I have 240,000 miles or so on my diesel, Sis had 160,000 on hers when the rad went (or the head gasket, hard to tell), and other than the interior falling apart, ran great. Newer ones are money pits, as my neighbors found out. They traded their 245 with 275,000 miles for an 850. Sold is six months later, it was eating them alive with repairs, some twice. The 245 had a head gasket once, the only major repair. Peter

Maybe I am lucky but my 1983 300D with 280K miles that I have driven since it had 80 K miles (1989) is still on its original radiator. I only use MB Coolant, which I change every 2 yrs..

Well, an icepick has more atoms than a marble, but I think the former would go further through my hand when dropped from a height! I guess I'm saying that molecular shape might matter. As well as composition given the bizarrities of chemistry. I think I'll stick to C and destroying LED's! -- Jim

Re: [MBZ] Mystery Water leak W123 300D
Check the bottom water pump weep hole for the presence of coolant -- water pumps, in the early seal failure stage, will leak at strange times. They may very well not leak while running, and hold pressure just fine, but dribble on cooldown at some point, then stop again. In later stages, they gush, that's easy to see! Peter
Re: [MBZ] Mystery Water leak W123 300D
Sometimes water will leak and drip onto a hot engine component which makes it evaporate, eliminating the evidence of the leak. Of course, the worst possible problem would be water leaking into the oil inside the engine. If this happens the oil can become milky looking when the water leak becomes significant. But 1.5mm is not significant.
