1999 Volvo Penta 5.0 GL freeze plug kits

[Garutlan]

Anyone know a part number for a freeze plug kit for the engine in the thread title. Was not sure if a GM cross reference would work. Thanks in advance- Geoff

Go to any auto parts store and give them the year and GM 5.0 and they should be able to find Brass or Stainless Steal plugs

Should also be able to find them on line at a place like Summitt Racing or Rockauto

 

[Garutlan]

I will give that a try. Thank-you for your help!

Napa keeps core plug kits in stock. marine use brass or stainless. cars and trucks use coated tin

Melling MPE-100BR is for small block chevies from 1957-2014

however if they were pushed out by not winterizing, the block cracked

Agree with post #4.----If pushed out by cold weather then inspection is required.-----They are " core plugs "----And somehow they began to be called freeze plugs.

 

[Garutlan]

Understood- I am going to inspect this weekend- with nicer weather. Thanks-Geoff

Remember, the block water jacket should hold 15psi.

the points of failure if it froze will be both exhaust manifolds will have a crack on either the outboard or inboard side, just above teh centerline of the exhaust ports, and both waterjackets will have cracked on the inside of the cam valley, and the heads will crack around the exhaust valve bowls
