Cooling system???
As some of you know I just bought a Late '99 F350 XLT CC Dually with PSD:
I have been around on the FTE since 1999 I think, and have had my share of Ford trucks, but this is the biggest baddest one yet for me, and I'm new to keeping up and maintaining a Diesel engine, I have driven many a BIG truck with a Diesel, but never owned one until now.
I have a good friend who has both a '00 F350, and a '04 F250 and he has given me plenty of guidence on them, but he seems to be away this weekend and I want to kind of freshen everything up including the coolant.
He has said something about Diesels having cavitation and there is an additive I should when changing the coolant, I also think its a good idea to change the thermostat, any tips on this as far as coolant type, or tstat temp?? should I end up with a 50/50 antifreeze mix like a gas motor?? Thanks!!

With a late 99 you should have green cooant in there if you want to stay with green then the FW-16 additive will be required and checked every 30K
The stock tstat is a 192* but www.dieselsite.com sells a 203* stat for our trucks. If you try to find a 203* locally make very sure it is a long stem variety of the 203*. The short stem that napa sells will not close off the bypass and can result in overheating the block.
If you do a complete flush (with distilled water) get 4 gallons of concentrate and pour in then top it off with distilled water (you will have a 50/50 mix - 8 gallon total capacity). It will take about 20 gallons of distilled water to flush it completely.

OK, Wow!!! So a little warmer tstat (warmer engine temp) is better for the PSD?? I didn't know that.
So, IF I want to stay with the old fashioned GREEN Ethilyne glycol anti-freeze I need the additive then???
Could/should I change/swap to something different?? Red stuff--does IT already have the proper additive in it??
Sorry for so many questions but I really want to maintain my truck right!!

the original 444E (7.3) has a 203 stat in it..for some reason Ford put in a 195..I have the 203 in mine as well..it heats so much better in the winter, and the truck seems to run a bit stronger..if you do the stat get the housing as well..here is the link for a stat and housing.
