Hey everyone.. I have a 6 port 13b rotor that is over heating... at first It hought it was a problem with thermo wiring, but now the thermo's are wired so that they run while the ignition is on...not just at a certain temp. The top hose is boiling hot... the bottom hose is hot..but ok to touch... I'm guessing that this is because the radiator has cooled the water..lol.  am I running into a simple problem with a simple fix like a new radiator cap or a thermostat? or is it sounding like its something more severe...like a water pump? help please! edit... btw... I have the dash temp guage and a aftermarket one... *dont know why...it was like that when i bought it* the one in the dash says temps are ok...but the AM one says that its getting too hot... I've never let it get into the red... I pull over before it gets too scary. Oh... and its my first rotor... thats why I am asking seemingly stupid questions. I've always had piston motors and so far have never had an overheating problem... which is why I cant figure this bastard out...

Umm... How hot is it getting? Do you have a water temp gauge? It is normal the top hose to the radiator to be very hot to the touch, after all, the normal operating temperature is between about 80-100 degrees celcius, so unless you have a gauge then you don't know if it's too hot at all. |

the guage appears to be a supercheap guage... like..with its own little L shapedsteel holder... |

So was it fine before and it's only just started doing it? Or has it started doing it since you bought it? Given that the standard gauge is still reading fine I'd be leaning towards it being an incorrect reading. By the the way, if it ever approached 250 and that gauge is correct that's way too hot. 210F is ~100C and is where I'd start getting a bit concerned and if it didn't go down pull over ASAP. 250F is more like 120C. |

perhaps it could just be cos the vehicle that the motor is in doesnt feed enough air throught hte radiator... the radiator is in a bit of an angle... and may have too much shit in the way of it... bumper bar, bull bar etc... might have to cut some holes in the bumper to feed some more air into it??? |

200f is roughly operational temp and only at about 230f would i be getting worried |

Get a decent thermometer and get an actual temp reading for it. One of the guages is obviously wrong, and you're assuming its the original one. But it could be the other way round. So get a third reading, and hopefully it'll agree with one of them. |

Does it do it every time the car is run? Only when sitting in traffic or idling and fine on the open road? Or the other way around? Or all the time, regardless of conditions? Do you have another gauge you could hook up to test it's accuracy? Does it just continue heating up from cold to overheated, or does it stay at normal temperatures for a while and then start rising again? Any chance of following the wiring and checking whether the gauge has its own dedicated sensor? Have you spoken to the previous owner about whether the gauge normall read that high? Finally, have you checked the coolant level again to make sure it isn't low again? I assume so, but it's worth checking. IT gets hot when I'm sitting still... which is why I thought it was the fans at first... it warms up... when its warm I start driving... its fine untill either I put my foot down a few times or i end up slowing down/stop at lights. then it starts to get hot. Previous owner said that he had always thought it was a problem withthe thermo's... My parents used to have the same car when we first moved here and my old boy reckons even the stock motor was bad for over heating... he said it could be cos there isnt enough airflow. The plasctic air deflector things have all been taken out of my one. Its still NA... Carby... the only other thing near the radiator is the oil cooler... but its under the rad. not infront. I've checked the coolant again. its still fine. green. 'll check for the wiring of the temp guage when I get home. I'm at work today and I drove my soarer. the hottest its ever gotten was about 230f thats when I pulled over and turned it off. then went and had a burger and a drink. then got back in and drove home. |

I wanted to go 13bt but when chatting to the mod plate guy he said that I'm balancing on legalities now so NA is the only way to go without getting into trouble... BUT..he did say that whateve I do AFTER I see him is my own business. lol. |

I'll see how things go though I might get it and put it in a smaller car... seems wasted on a Van. believe it or not they are out there , you just never see it, and they arent exactly standard

I spose anything is possible... just depends how deep...and empty your pockets are. lol Thanks for the help guys. I sold the car in the end and the new owner is sourcing a new motor for it. Cheers for your time! |
