Cooling parts for Chryslers

 

These are some of the pesky riser parts

 

Hint: Take (or borrow) a laptop to the boat. and go to a site with a very good catalog (or print out), save the web page so you can see the parts as you need them. I put the parts I used with location and catalog numbers on a page.

 

Order the riser and elbow parts ahead of time, these are the parts I used to replace everything except the manifold, from http://www.marineengineparts.com who I endorse. You may need more "plugs" than come with the riser.

 

I'll assume you just bought your boat. How to tell if you have a freshwater or raw water systems, 1) look for a plastic radiator fluid cooling bottle or 2) look for a radiator cap on a big metal tube (a heat exchanger).  Fresh water systems use antifreeze in the engine block, and raw water systems use river water in the engine block to cool the system.

 

 

Raw water systems are common and not as much of an issue as some might think. (My previous boat had raw water cooled engines that were more than 25 years old. My new boat has a fresh water system. Hint: The end gaskets on a old style heat exchange match the mercruiser part.

 

Important

Tip #1 for newbies. Like wiring,  replace each hose one at a time. Don't yank them all off.

bullet

Tip #2 If you don't know... expect to replace all the fittings and buy them ahead of time.

bullet

Tip #3 Somebody else's engine is not yours. Don't assume, look and see before you order. I have a box full of perfectly good ass-a u and me parts. It's harder to find the parts than it is to fix them.

bullet

Tip #4 Take a camera and laptop to the boat. Write down the parts you buy and that fit. Snap pictures, as you'll have forgotten in 2-3 years. Don't order from someone that does not know Chryslers, Crusaders or your engine in detail.

bullet

Tip #5 Keep the invoices in a folder.

bullet

Tip #6 Cheap hoses and clamps bite... don't use them.

 

 

 

Finally decide what you plan to replace... remember safe, then reliable, then cosmetic. Cooling is a safety issue.

Unless you have done this before, it's easy to damage the O-rings when you install. So order an extra O-ring.
