Thank you for all the good info!

Hi all, as a very new owner of a MEP-802A, I immediately discovered two things: the coolant had all been drained out of mine, and the bottom radiator hose was in terrible shape -- in fact, when I pulled it off the twisting created huge cracks throughout.

The radiator hoses were challenging to find, but I did find one outfit that has the upper (88-20189) and lower (88-20190) hoses for $20 each. I figure if my bottom hose is in bad shape, the upper can't be far behind so I'll replace both.

The site I found them at is www.teamequip.com. I have no affiliation with these guys.

Wow, Excellent job I have been looking for those hoses for ages. Only 3 left for one of them

 

[flainn]

Confirmed that Team Equip is legit; I got my hoses in the mail today.

This thread is about MEP-802A parts. These hoses are MEP-802A parts. You'd prefer I started an entirely new thread for this?

Radiator Cap (or in the manual "CAP, FILLER OPENING")

Manual shows Stant R28, which crosses to Stant 10228 which crosses to NAPA BK 7031696

That lower hose is now $49.95 on that site
