Cat ELC Coolant

[Switchrider900]

I have looked for a thread on this but have had no luck. Don't like reposting topics, so sorry right off the top. Looking at doing my coolant this weekend.

First off, should I or do I need to use VC-9 and Restore. If so what order should these products be used?

Do I need to pull the Thermostat?

I know to use distilled water when flushing and re-filling the system. Just not sure how much I will really need.

Now the quesiton, if I get the Cat ELC coolant, do I need to add distilled water to the coolant or do I just put the coolant in straight? If so, what would the mix be? I live in Canada, so our temps can get pretty cold in the winter.

Thanks in advance for the answer if you can help.

I would also like to know this. I do know the ELC coolant comes in 100% concentrate or 50-50 mix (assuming mixed with distilled water) Leading me to believe that it should be 50-50 mix when done.

Per PGreenSVT's recomendation in another thread I found:

Drain coolant by removing lower radiator hose. Drain block from plug on drivers side of the block. Remove the thermostat. Replace plug in block and put lower hose back on. Put thermostat housing back on without thermostat. Fill with water. run for 5 minutes then drain as above. Put 2 qts of VC-9 and fill with water. drive it for about 45 minutes. Drain and flush after. Put in 1 gallon of Restore an top with water. Drive it for an hour then drain. Flush 2 times with water. Flush 3 times with distilled water. Replace thermostat or put in a new one. Add 3.5 gallons of ELC concentrate and top off with distilled water. Make sure to run engine for 5 minutes between flushes. Have heater on set to hi while doing this to flush the heater core too.

I haven’t changed mine yet. I am waiting for my Edge I ordered last night to come in. I figure I should see if my oil cooler is ok before I make the switch. Don’t want to waist new coolant.

So, SVT and others. Is there a onetime use gasket on the thermostat housing like most other motors? Just wondering. If so, it might be worth me just going to the dealer for a flush and fill with my Cat ELC.

Yes it is a single use gasket IIRC. You can always forget about the gasket and seal it with Black or Blue RTV sealant.

Questions...I have seen a couple of places that say you don't have to/shouldn't drive it for 45 minutes and an hour if the thermostat is removed. True, not true? I am doing the flush tomorrow. How hard is it to get at the plug on the drivers side? I got the VC-9 and restore but I need to get the coolant in the morning. I think I am going to go with Cat because I can't find any Delo locally. What kind specifically do I need to get from Cat? I need to buy 4 gallons and put in 3.5? Anything else I am missing/need to know?

2004 F350 SRW if that makes any difference. Thanks a lot for the help!!!!

I cant pay attention to your question. Your Avatar has my attention HOT!

Yea, I got to flush my system too. Waiting till Edge comes in to see if oil cooler is good. If it is I am flushing. I will probably do it the long way and keep the thermostat in.
