Just got the car, embarking on the normal maintenance. Fixed a fuel leak, parts coming tomorrow for other stuff, filters, multi function switch, hazard switch, etc...

I noticed that maple syrup smell with the heat running after getting the car home. I think it's more on the passenger side than driver. No visible leaks or low coolant. Not overwhelming, just there when the heat is on.

Coolant is dirty. Too strong, looks like mud, drained it, recovered just under 2 gallons between the radiator and block. Starting the flush procedure. I noted no one sells heater core for one of these.

Any tips? Do the cores go bad on these, or should I look elsewhere (o-ring? valve?)? I did see this post: http://www.peachparts.com/shopforum/diesel-discussion/413157-last-thing-ill-bug-you-guys-about-coolant-flush.html
