Yanmar coolant expansion tank

Posted by ajlorman (ajlorman@…>)

I recently had to replace the leaking coolant overflow tank on my
2GM20F. The tank is made of polypropylene and almost no glue would
seal the crack that had developed. I checked the price of a Yanmar
replacement and was outraged to discover it was $76. (I don’t know
why this surprised me so much; I had to pay $175 for a warning buzzer
for the Yanmar panel.) I simply refused to pay that and went looking
on eBay for an automotive tank that seemed about the right size.
Tanks for cars run from $10 to about $25 and there is no magic in the
shape, other than fitting in the alloted space. I ordered what seemed
a reasonable replacement for $20 and when it arrived you can imagine
my surprise to discover that it was an exact, drop in replacement. I
didn’t even need to change the mounting bracket. The seller is still
advertising them on eBay, though without mentioning that it fits the
2GM20F engine. I just wanted to share this beat-the-Yanmar-system
link with the group:

Al,

Make sure you use a pressure cap with the same opening pressure
setting as the original. Or use the original cap, if it fits. You
might risk your hoses.

The pressure cap is, if I understand it correctly, mounted on the engine, not the expansion tank. I have a regulation Yanmar cap on the engine.

Anent the Yanmar coolant,when I spoke to a Yanmar service rep,a comment was made regarding coolant types,and a diesel specific coolant was recommended… It has something to do with vibration,cavitation,and other esoterica. I got Caterpillar coolant,already premixed 50/50 with demineralized water. Cat dealers are all over,and being generally non-marine,are not crazy on prices. 2 gals were less than $20

Oh okay, that’s a bit different setup than I thought. As long as you
have a pressure cap somewhere to protect the hoses against over
pressure.
