New Radiator/coolant Installed

[donutdavid]

Hi all,

Just wondering if anyone has seen this before.

My original radiator top tank gave way so I went and bought a/market alloy one and installed it.

Also added new "nissan" coolant with destilled water of course all good started and worked well (weekend).

However today just went under to check for leaks etc. opened the cap to see if need any top up I've noticed strange black spots floating in my new radiator.

Tested with clean white rag and it appears to be oil black dots in my coolant???

Should I be concerned? Should I replace the coolant again???

Need your thoughts please.

Cheers

Dave

i would replace coolant again and flush the radiator and should be ok

this could be a sign of bigger issues. it could be a sign that your headgasket has let go, which could also explain the end tank letting go.

i would flush the coolant and put new coolant in and check it again in a few days. if it happens again then i would take it to a mechanic.

Thanks for your reply mate I think your right.

Anyway took it for a drive around block tonight and the water remp is sitting around just above the half way mark and oil temp is showing 90 degrees.

seems fine for now, I'll post back with new coolant.

I don't mean much over half way at the first glance its spon on but when you look closer just a tad over and it stays there, I think the good sign is "stable" temp and not rising.

I'm still amused how things never stop going wrong with gtr, but it all goes away once you take it for drive.

I think thats the pitfall of owning an older car. My 94 gtst is showings its age, I get all sorts of minor niggling problems. Still its been pretty reliable given its age.
