The CEM product is available over the internet from Cost Effective Maintenance. They post it free unless you add the decarbonizer to the order, as that has special couriering requirements.
I recently purchased some to attempt to solve an elusive overheating problem in a 1989 Hi-roof, GQ Patrol, that has had an aftermarket turbo added.
This vehicle has been sucking down 20l/100Km, and runs at 50% of temperature gauge all the time, then boils if taken on long climbs.
So far I'm still awaiting the results, as the flush was only done on the weekend. I ran it through twice as the history of the vehicle indicates that it has been used touring and so could have had all sorts of poor quality diesel put through it. It has however got an immaculate service history log-book, so didn't feel that the engine would be in such poor state that the product would do the harm that I understand can be caused to very bad engines.
I'll keep you informed of how it goes once the treatment is completed
After the double flush of the oil, the temperature never went over 75% on my test hill
. This same hill
used to boil me half way, now I get to the top but as far as I'm concerned she's still running seriously too hot.
I can't say about the fuel additive as I'm only a 1/4 of the way through the tank I added it too. Though I believe - and may well be mistaken - that this product makes the fuel burn "hotter" as part of the cleaning process, which may account for why the temp has come down, but not come down far enough yet.
I know that we've tried a complete cooling system rebuild with 3 core radiator, new pump, thermostat, hoses, etc etc. and that I basically didn't have much money left to keep playing around with, so decided that at $99 if it didn't work then no real harm was likely to be done as the engine is in quite good condition and has only 250,000 on it.
I only got a little more oil out than was in there, and not terribly bad oil. But it has stopped the small puff of white smoke when starting first thing in the morning.
