2003 GT Spec-B Legacy - Coolant Leak

Recommended Posts

2003 GT Spec-B Legacy (auto) has developed a slow coolant leak. First noticed after no hot air through the heater. Checked coolant, was very low (resivoir, rad and overflow bottle). Top up with some water and run the car, heater hot and all normal. Car has/is running fine no overheating at all.)

 

Can't see any leaks in hoses/cap/connections, no water in the oil and vice-versa. The sponge on the top of the radiator is wet after a drive (30km) say, and dribbling down toward the passenger side. Looks like a leak in the top tank?

 

Cost to get pressure tested vs just chucking a new rad in? A few on TradeMe, if so anything to watch for etc. Want to sell car in the next few months, so aren't really too fussed on upgrades as such.

 

If so, know anyone in Wellington that could help?

 

Cheers

Might have a hairline crack in the top tank, assume it's the usual black plastic one? Or a small split in the top hose that only makes itself known under pressure.

 

NFI what pressure testing costs. If you were keeping it I would say just grab one of the ~$200 alloy ones on Trademe, since you're planning to get rid of it I would just go get a radiator from Pickapart..... is yours a very late BE/BH or very early BP/BL?

You're correct, it is the OEM plastic tanked one. I checked the hoses and they seem ok, checked top while running and couldn't see any obvious leak under pressure. 

I ended up getting a brand new off Trademe, just a plastic one still for like $160 shipped so will see if that solves the issue. 

 

Although, a friend told me his did this and it was the hard line across the top of the rad to the overflow was blocked and was forcing it back out and leaking. Need to check that too.

 

Early BL, 2003 sedan, Spec-B, think it's a PFL, but top spec PFL... Or FL of the earlier gen.
