Coolant/Coolant Filter?

[ewmoose]

I am going to do a coolant filter install and want to know if it is necessary to do a coolant flush? Truck has 80,000miles on it with spartan 275 tune, EGR still installed for now. If I need to do the flush, is it necessary to remove the thermostats? or can I leave them in and let the truck run longer i.e. normal driving? Wouldn't adding the filter along with new coolant and frequent filter changes do the same over time as a flush? or am I thinking crazy? Thanks for the help.

If you have Ford gold coolant I would do a flush.

If I need to do the flush, is it necessary to remove the thermostats?

IMO yes, the coolant circulates faster without the thermostat so it flushes the heavier crap out better.

No, using just a filter is not enough. Only doing a chemical flush will get all the crap bonded to the inside of your block out.

When you do an EGR delete leave your EGR valve still plugged in.

Side effect of disconnecting EGR valve

shouldn't he install the filter first run it for at least a little bit to get some of the casting sand out then do the flush? thats what I'm doing I was hoping it reduces the risk of clogging the oil cooler

I have heard some guys who do that. I did a few flushes with just distilled water and I got a pretty good bit of sand out just by flushing with water. I drove for maybe 150-200 miles before I did the restore and restore plus chemical flush. I didn't cut my first filter open to see how much sand was in there. I don't think the sand is the big concern when it comes to clogging the oil cooler.... I think the bigger chunks of sludge are the culprit.

If you are thinking of doing an egr delete I would do it at the same time as the flush. You will loose coolant while doing that so might as well do it all at once. I just got done doing my egr delete and flush 2 weeks ago. I got some sand back but not as much as I was hoping, I think Im going to pull the trigger on a filter now and see what I get back.

Wait until you have the egr delete. Do a full flush once you install the coolant filter and egr delete. I would get restore/restore+ when doing the flush it will help clean the system out better. Use cat elc when you are all done

Thanks for the replies folks. I am going to order the filter tonight, don't want to do the EGR delete until I hit 100,000 scince there is no going back with it once you remove it. As it stands now, I could replace my stock tunes and exhaust and get warranty work if needed. I will do the filter and flush for now and EGR delete in 8-10 months when I roll over 100,000 thanks again for the help.

Just curious, what kind of coolant did you use?

I put on my coolant filter for a couple thousand miles before i flushed the coolant system. It did get a lot of the sand out. I also got a lot more sand and gunk out when i flushed with VC9.

I used the Cat elc. I know the local cat dealer owner so I got a good deal on it.

I just bought 4 gallons of cat elc was $101. Do the flush and replace it with this and you will be happy
