Changing to a closed system

[Davenc]

Ho hard is it to change a Volvo 260A fresh water cooling system to a closed system? Is this some thing that a novice shade tree mechanic (me) can do?

I Think you mean,....."How do you convert from Raw Water Cooling to Freshwater Cooling?"........<br />Freshwater Cooling Is a Closed System,.....<br /><br />Anyways,....................<br /><br />Ayuh,......<br />It Can be done,.... FreebeTony did it to his old I6 awhile ago.......<br /><br />The 1st thing you're going to Need is a Factory Service Manual for your Engine/Driveline.........<br /><br />Most times,.. The Damage has Already been Done,+ There's No Reasons to Justify the Effort,.. Or the Expence........<br />If you're doing a repower,+ getting New Manifolds to go with it,.... Then it's Justifiable........<br />If your engine has Time on it,.... The Salt is already there,+ There's No Amount of Flushing is going to Clean it...................<br /><br />Good Luck,.......

Thats what I meant. <br />My engine is fresh. About an hour on it. Some one asked why I didnt do it and I simply didnt know I could.<br />Is it easy?

The plumbing route will be altered,+ a Heat Exchanger is Added,.......<br /><br />You can either scavange the Volvo parts,......<br />Or,... There are several after-market systems available..............

What I can get is a brand new system from a local marina for 450.00 bucks. I already have to get new risers and manifolds.(which I didnt know)<br />So every thing comes to around 900 bucks.<br />From what I have found on the NET, I guess these prices arent to bad.<br />Thnx for the help.

Re: Changing to a closed system

If you can get a Large Enough Heat Exchanger,... You'll be able to include the Manifolds into the Freshwater side,...This is how My latest is going to be,........<br /><br />But,..... You'll Still need to Replace the Risers every 3 or 4 years,....They'll still be on the Raw Water side,... No changing That.....
