Oh I misunderstood I thought it happened all of a sudden.if its perfectly ok when moving but the temp starts to creep up at idle I gotta go back to what has been mentioned earlier not enough either air flow or water circulation(or a combination of both) but you've covered about everything so something that has already been touched on is not doing it's job. If I had to GUESS if I was sure that there was plenty of air flowing thru the rad then I would bite the bullet & get a better radiator(more area,more cores).The more I think about this if it was my deal I would buy a GOOD radiator.

I have a GOOD rad, actually it cooled fine last year it's just this summer. I don't want to throw parts at this and waste $$$$, everything is new....it's gotta be something else; the cooling system is fine. You can feel the air flow at idle at the grille outside the car and it feels quite strong. If i open the hood you feel tonns at air come thru the rad. it easily sucks up a sheet of paper to the face of the rad...i don't see buying a new rad as a solution...

If you idle with the hood up does the temp still creep up?

well in gear yes, idle the N or P with the hood open or closed, perty much stays 180-185.

Think your block passages are pristine ? If you haven't had it hot tanked yet, knock out one of the core plugs and tell us what horrors you see !!

I have to agree with this.

I don't know what i have to say for you guys to stop with the dirt in the motor, it's a <10000mi build that was hot tanked, cleaned by a rep machine shop. Plus the rad is new and a 3 core i just looked at it with the fluid drained; which by the way looks like it's new out of the bottle. IT'S NOT THE RAD/BLOCK, 110%. I would consider a blown head gasket before i suspect a good motor build/new rad for crud.

I've been following this one for curiousity's sake-one thing I thought of- maybe your damper has slipped and the timing is retarded. Confirm TDC.

try putting a cap on the vacuum advance . put all of the timing in mechanically. It is a free suggestion. put a piece of duct tape on it for a test if it works spring for a fancy nipple cover.
I have a 470" b engine with a 22" radiator. no fan shroud, 5 blade clutch fan. 34 deg total all mech. vac advance plugged. runs 180-185 deg.

You have covered a lot of areas, but are you sure you do not have any vacuum leaks at the intake that would lean out your fuel mixture at idle causing the temp to rise?

---

Well this was my train of thought, the car has 17" of vaccum at idle hot in gear (650-700rpm). So i could possibly rule out the intake as leaking. I did re-torque it, it was not loose at all, nice and tight.

I changed the fuel pump, filter, and i'm going to completely take the carb apart and clean it (hopefully i'll find something). If all that checks out ok, i'm going to then concentrate on iginition. Maybe something is getting hot/failing like the ecu, coil, ballast resistor, pick-up. i'll change one part at a time to see if it gets fixed.

If that does'nt work, I TOTALLY GIVE UP!!!

What i have just done:
-flush/drain cooling system (old coolant by the way was like NEW/very clear/clean).
-new rad cap.
-high flow stat 180.
-milodon high flow water pump.
-new heater hoses (were too close to exhaust manifolds).
-new carter fuel pump and new fuel filter.

When i start it, i'll re-adjust the idle mixture with a vac guage, check timing, and

At this point i'd be happy if the car would run 190ish and NOT DIE on me. If it'll hold temp at under 200 when it's hot and not die i'd be happy as a pig in $hit!!!!.

Also today is stupid hot in Toronto, so tonite will be a good test, wish me luck.

whats your convertor , stock ?

yes, stock. everything is stock except for the new parts i just put on, eddy CH4B intake, and eddy 750 afb carb, TTi 2.5 exhaust with h-pipe, stock exhaust manifolds, 70+ voltage regulator with 3 wire alt, mp perf ele ign.....
