Buying a Legacy 3.0R - What should I know about them? Waterpump replacement?

[Guitar_Guy]

Hey guys,

Looking at purchasing a tidy 2004 BP5 Legacy with the H6 motor, its done roughly 130,000kms.

I am aware these are a chain driven engine and while this saves the usual 100,000km service,

do they still need a waterpump replacement?

Feel free to post any other service related info on these as well, I don't know a crazy

amount about them and would like to avoid buying a lemon although I am going to be shopping

at dealers only for this.

Thanks in advance!

I have seen alot of H6 subaru's with 300+ kms on the clock and none have ever had issues with water pump.

The 3.0 H6 is the most reliable engine and service intervals are every 10.000kms.

Hope this answers your question

Definitely helps that's for sure! Certainly gives me some reassurance in the reliability area. Thanks!

Something my useless brain has acquired knowledge of...

Even though they don't need a cam belt replacement due to the cam chain, they still need the the accessories belt replaced, along with the bearings in the idler pulleys. If not replaced, the most common problem is the bearings in the idler pulley that is mounted off the A/C mounting bracket, collapses, which along with letting the belt have a party against your radiator, also damages the bracket. Its a common enough problem that those brackets are usually the first thing to get robbed off a ez30R when one turns up at the wreckers.

Other than that, they are mint. They cope with been abused for along time with out complaint.

Im not sure if this applies to subaru, but I had a Duratec V6 with chain camdrive, and that did require the chain tensioner to be replaced/readjusted every so often (can't remember what interval at the mo). I'm guessing this would be part of the 10,000km service?

Water pumps are a weak point in the ez30.done mine at 160 and done a few at 220-250. Chain all show no wear. Lh tensioner can cause tapping at cold start. Never replaced a chain.

But otherwise a great motor with small niggles to work out. weeping head gasket would be worst major problem and relatively common

Tensioner on passenger side head is always worth replacing while water pump is off

ALSO, always ensure oil level NEVER drops below the Low line... otherwise the big end bearings will quickly make an appearance in the sump
