Well I ended up getting a Prestone back flush kit and radiator cleaning solution and flushed quite a bit of gunk out of the system. I have flushed the engine before installing but I guess over time more loosened and was clogging the coolant system. I also used a bottle of redline water wetter and I can happily say at idle I can get temps down to 80c with just one fan.

Thanks for all input!

I need to do this as well. I have/had quite a bit of rust in my system. I flushed most of it out when I drained the radiator, but I can't get to the block drain bolt. So I just kept flushing the radiator.

Are you in the USA? How much did that Prestone flush kit cost?

can people put up there power figures also, because its alot harder to keep a high power car cool than stock power.

depends, is power relative?

my car is only ~135awkw thru an auto, so prob 150-160rwkw in a manual r33

but my old datto had 100ish rwkw from a 35yo(rebuilt) "standard" 1.8, it ran at 72deg all day every day, engine fan, no shroud, re-cored stock radiator from what i could tell, and it was bored/stroked/ported... so you would think with the higher tech stuff it could be kept cooler? just get a vipec and run cycle idle :cool:

I hit 100 degrees the other day giving it stick and holding, it in the middle of the day (was a bloody hot day). I'm going to look into a decent PWR radiator or something along those lines soon. This was the first time it has hit anything over 92. However i don't have an exhaust manifold heat shield on there at the moment cause i havn't had a chance to get my new one made yet, so this could be contributing to under bonnet temps.

Note to self, "Townsville day heat plus giving it stick with 450BHP, bad".

The kit and flush solution was about $15 from pepboys.

I would suggest trying again to remove that block bolt, I've found that a lot of gunk accumulates back there and the only way to remove it is to remove the bolt & flush.

i got pwr radiotor std clutch fan and shroud nismo thermostat 62 deg i think

rb25neo in r32 276.8 kw at the wheels and it runs too cold at 76 deg for cruse always in cold corection unless i thrash it then might get into mid 80's

One more question before I attempt this tomorrow (I just installed a FMIC and now my temps reach about 195F/90C):

When you did the flush, did you remove the block drain plug? I tried using a cordless impact wrench, and that wouldn't even work.

Take it for a power flush and rod the radiator.

Involves disconnecting the heater pressure flushing heater and block.

If you do run an engine flush without a pressure flush grab a stocking and shove it over the top and bottom rad outlets to catch any crap.

    • Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
    • Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
    • @KinkstaahKrinkle paint the "silver" alloy, not the red filter frame Engine bay heat won't be a issue worth worrying about as the silver alloy blocks it off on 3 sides, as for the top, the bonnet seals most of it and the big OEM CAI intake snorkel is still fitted in its original position  I will head into Clark's Rubber when I have some time to grab some pinch weld to tidy up the alloy after I paint it As for performance, I honestly wasn't expecting any, the only reason I got it is because the intake noise sounds cool to my old ears when I'm feeding it the beans Sometimes it's the silly things you do in in life that gives the most fun, and I do love anything that makes cool car noises In other news: I survived 4 nights at sea with Jackie not throwing me over board, holidays are continuing now as we are currently chilling at the Beachcomber in Toukley, after taking the coast roads from Sydney in the MX5, top down all the way, Toukley is where I spent a good deal of my youth holidaying during the summer months, there's lots of reminiscing going on,  and lots of beaches and old houses to visit Next on the list is to head to Batemans Bay for a few days, but we will take the Commodore out to stretch its legs, then Commodore hasn't really moved for months
    • There’s probably people who’d like to do it and then when it comes to putting their hands in their pockets they’ll all disappear into the shadows 
    • interesting....sounds like the later trans has software differences (or AM vs JDM). If I wasn't going down the tuning route it would be worth looking into retrofitting a new computer to the old box.
