HI ALL,,,

I have a r33 with RB25, Power Fc with hand controller,

Up untill yesterdy all was fine, not had a prob before with it.. water temp would sit 78 - 80 once fully warned up after (about 5 minutes) and might creep up to 83 after few hours driving,Fine right? been like that for years

Right,

My cars been sitting in the pannelbeaters the last couple months, (front bumper damage and minor side pannel damage) the radiator didnt get touched atall in accident baring in mind, but they had to remove the rad to do work, when i went to the place yesterday car was running, they said it had been running a couple of minutes and i looked at Fc hand controller and Water said 60.... i then revesed straight out of the unit (20ft) got outta car. talked for honestly no more than two minutes, Got back in car and hand controller was reading 114c!! pannelbeater says nah that cant be right because the stock temp gauge is only reading just above halfway mark?

Please all! Am gratefull of all advice!!

CHEERS AGAIN

Let it cool Nd check the coolant level. If its ok leave the cap off open the air bleeder screw on the inlet manifold till coolant comes out then refit the bleeder screw and start the car, let it idle till it warms up with cap off and heater on.

This should remove any air that is still trapped in the cooling system.

If it still overheats get a new thermostat

in my experience, the stock temp gauge reaches half-way around 60-65C and will stay there till around 110C before rising - so it could be easily right.

+1 on bleeding the coolant system too.

You may have air in the sysyem, When the car is cool remove the radiator cap and start the car, let the car idle for a while(might take 5-10 minites), giving it a few revs here and there, watch your temp gauge, and add coolant as needed, also ensure you have some coolant in the overflow for when the car cools down so it doesnt suck air back in.

Might fix it.

Basically from my experience the stock temperature gauge should always be reading just under 1/2 way for a normal operating engine at normal temperature.

If it gets to 1/2 mark then thats enough to throw a caution, anything over 1/2 means there are potential over heating issues with the engine.

I had my gauge read just over 1/2 way & when I pulled over the coolant was boiling in the reserver tank, even though according to the stock gauge it's no where near the H mark, had it checked & it turned out to be a worn Rad cap & thermostat.

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it

      Good tips, I like it! 😂😂 My wife is a LOT more frugal than me so it's only me we need to worry about! A splurge to her is buying 2 pairs of socks in one visit at Kmart!

      Haha, the appropriate response to the question "Is this new?" is "I've had this for a while.". With the unspoken small print that a while may be the time since this morning or five years ago   And to be fair I learned that from the best, i.e. my wife. Because it goes both ways.
