One mechanic I talked to said he would put any color coolant I wanted in the engine. ;^) While I certainly do think its a bad idea to mix coolants, and MB coolant is certainly preferable, I do NOT think green coolant is as bad as some people say.

The only thing that did was replacing the radiators.

Can't see why the gasser would have it vs diesel not. My 220 gas was the base-base-base model. Manual steering, locks and transmission, crank windows, no AC. Easiest test: get the engine good and hot. Open the hood, rev the engine to about 3000rpm and you should hear/feel the fan roar. At higher RPMs it should disengage, theory being that if you are at higher RPM you are moving quickly enough that there will be natural airflow through the radiator. If you want, you can always test by rigging up a "lock" on the fan to prevent the clutch from slipping (wire wrap or something). If it still runs hot with the fan locked, that implicates the radiator. In all probability, the radiator is shot. I had mine recored; it was a piece of cake to remove (no oil cooler and no transmission cooler). They did a fantastic job on the rebuild for about $300. Long shot: does your thermostat housing have a bleed screw like the M115 and OM617.91 engines? If there's air trapped at the thermostat, that could prevent it from opening fully. D.

My 240D certainly doesn't. -- ---------------------------------------------------------------------- David Bruckmann, Temescal/Oakland, CA 1966 Citroen DS21M Pallas "Celeste" 1970 Mercedes-Benz 220/8 (250,000 km) "Blanche" 1972 Mercedes-Benz 280SEL 4.5 (160,000 km) "Blauer Engel" 1973 Mercedes-Benz 450SLC (210,000 km) "Lottie" 1976 Citroen 2CV6 (150,000 km) "Piaf" 1976 Mercedes-Benz 300D/8 (225,000 km) "Willow" _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com -- OK Don 2001 ML320 2012 Passat TDI DSG 1997 Plymouth Grand Voyager _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com -- OK Don 2001 ML320 2012 Passat TDI DSG 1997 Plymouth Grand Voyager _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
