Fascinating. This isn't the first time I've found conflicting information in different publications. In summary:
TheTDM says turbo is 80-100, while non-turbo is 85-94. The FSM says turbo is 80-94, while non-turbo is 85-100. The CD-ROM is vague but implies 85-100 for both. The EPC only shows opening temps, and says turbo is 80C, while non-turbo is 85C (not the same part number). :-) -Dave M. > ------------------------------ > Date: Thu, 29 Dec 2005 11:48:00 -0500 > From: Marshall Booth <[EMAIL PROTECTED]> > Subject: Re: [MBZ] SOS - '87 190Dt Overheat! > > > Dave M. wrote: > > I think Marshall got the numbers confused.
