[MBZ] OT - Filterfor coolant?
Does anyone have any ideas on how one might filter coolant on an engine? I admit I have not done any sort of google search etc. I am just putting this out here to see if anyone has encountered such a device or has ideas of how one might create such. The gist of it is that I would like to filter coolant on a boat engine. I have an inboard outboard that has been run for years with lake water pumped through it. - Only fresh water so not an issue of salt water corrosion but never-the-less somewhat rusty looking inside. I would like to install a closed system setup so that the engine uses anti-freeze and is cooled by the fresh water going through the heat exchanger. The folks on the boating forum suggest this is not going to work because the rust particles from the engine will clog up the heat exchanger passages. They say it should only be installed on a new engine. So, my thought is that there must be some fairly simple way to filter the water flowing through so that I can trap and remove the rust particles. There is some space available on a boat so not like trying to fit something under the hood on a car. Ideas?

Re: [MBZ] OT - Filterfor coolant?
You can pick up a stainless filter housing on eBay that takes standard filter cartridges for $100. Don't use plastic. Any filter media will reduce the flow somewhat. Determine the largest particle size you want floating through the system and work back from there to get the flow rate you need. McMaster has a wide variety of filters. -Dave Walton On Friday, October 12, 2012, Randy Bennell wrote: Does anyone have any ideas on how one might filter coolant on an engine?

Re: [MBZ] OT - Filterfor coolant?
Randy, I am only familiar with smaller engines that use heat exchangers in marine applications, but even with them the tubes in the heat exchanger were easily 1/4 of an inch in diameter at least, so I can't imagine there bring enough cruft in the engine to plug them up. As for a coolant filter, I have only seen these on industrial Diesel engines, and they were more of a means to introduce and maintain DCA (decavitation additive) than to actually filter the system, as they were relatively small, the size of a typical spin on oil filter, and had a minimal amount of coolant flow through them. I would think that if your coolant is clean and properly mixed, there would be no issue with converting it to a closed system.

Re: [MBZ] OT - Filterfor coolant?
I would like to think you are correct but I don't want to over heat the engine. I am told that is a no-no with these engines. What I have is an old 165 HP inline 6 cylinder GM engine - 250 cid. Basic GM block used by Mercruiser for a number of years in the 60's and 70's. I bought a heat exchanger that I am told was originally used on that engine on ebay last winter. It had been retrofitted for use on a smaller inboard engine in a sailboat for a number of years. The sailboat underwent a bit of a rebuild and at the end of the day they installed a new engine with its own cooler setup. Before that happened, this heat exchanger was cleaned up and was ready for re-installation. I have not taken it apart but I have photos of the inside of it somewhere, from when it was cleaned out. It does look as though it has reasonably large passages through it. So, the filter idea may only be a temporary thing while I see how much gunk is showing up. I wonder if a screen of some sort might be sufficient just to see what appears at the outset. However, as I said, I don't want to ruin the thing. I am told that if one overheats this engine the head will warp and it will then need extensive work. My whole reason for wanting to do this change to closed cooling is to make a cabin heater more viable. One can run a heater core off of the engine like in a car and I am told it is much more effective with a closed system vs a raw water system. For those spring and fall days, it would be nice to have a heater under the dash that would blow a bit of warmth back at me.

Re: [MBZ] OT - Filterfor coolant?
Simple screen would probably work just fine, need a large surface area. Might also install pressure gauges before and after the heat exchanger to measure the pressure drop, if the difference in pressure is more than a few pounds, you may have a problem. -- Max Dillon Charleston SC '95 E300 '87 300TD Randy Bennell rbenn...@bennell.ca wrote: I would like to think you are correct but I don't want to over heat the engine.

Re: [MBZ] OT - Filterfor coolant?
If your boat has not been in salt water, used regularly, and correctly winterized there will be some sediment in the bottom of the block but not the big flakes you see in a salt water boat. If you are looking at a full FWC kit which also runs the antifreeze through the exhaust manifolds, I would replace the manifolds, remove the core plugs in the block and blast the coolant passages in the block with a pressure washer and not bother with a filter. If doing a half system, just do the core plug thing. Since the antifreeze goes around the outside of the cooling tubes in the heat exchanger there is alot of area to clog and it probably will not create a choke point. Your other option would be to use a sea-strainer (usually found on inboards and jet boats to catch sand or seaweed in a cleanable basket) inline in front of the heat exchanger. dave Wa.
