On a trip this weekend my '96 disco over heated. The only way I realized this was I stopped the car. The gauge read normal the whole time. The Thermastat seems to be working, the water is pulled into the system fine. |

hmmm the gages arent the most reliable creatures, in all reality stock gages arent on any car. if the fluid level is normal, check the radiator closely. the space between the a/c condensor and the radiator gets crap trapped in there and that can cause problems. if that is clean you may be in need of a new radiator. check with nathan crabtree for that part. they can be cleaned and rodded, but you can future problems with that procedure and i dont recommend it. best of luck |

the area between the radiator and condensor seems to be free of crap. How do I get in touch with Nathan Crabtree about a replacement radiator? |

As far as I know, the termostat is also on a clutch-style system rather then on an electrical setup, thus its on all the time. The benifit is that it keeps the temp consistent, whereas an electrical one, lets the temp go up to a certain point before it kicks the system on. I've let mine idle for a long time and it moves only slightly if at all.
Let me know, becuase if I'm wrong. I could be in trouble. |

You should not have any problems by having your radiator "rodded". Rover radiators are all metal. This is the same construction that radiators had from the start. The radiator shop will take one of the side tanks off, rod the core, clean it in the chemicals tank, resolder the tank, pressure test and paint it. All of this for less than $75. Call them, they will be very familiar with Rover radiators. |

Also put a new thermostat in and check/replace all hoses. |

What are the drawbacks of having the radiator rodded? This seems as though it would be a good cost effective alternative to buying a new one. |

one of the issues i have with rodding a radiator is that if there is a leak then they plug that particular tube. given enuff leaks and plugs you will lose effieciency. also rodding is more than acid bathing they actually take a rod insert it into the radiator tube and punch it out the other side. this in itself scares me. these cleaning rods can cause scoring in the inner tube wall. if per chance there is a large enuff gouge in the tube wall then you are at risk of developing a leak that may not be discovered in the pressure check. alot depends on the shop doing the work,(legal disclaimer: this does not apply to all radiator shops), the job is a hot-dirty one that is often given to the least senior guy in the shop. this is usually some High School drop out who is way under paid and is more concerned about feeling up mary jane rotten uh...well you get my point. there are alot of good shops that do really good work. my thought is this, if there is an error in the workmanship and they damage your radiator and its not caught by the pressure check, is it possible that the fault will manifest on the Moab as you are motoring along or its sub-zero and you have you family in the trusty Disco and it lets go when you are 50 miles from any town. its not worth the risk, buy a new one.

Well there are your pros and cons. Each person has to decide what the trade-offs are. My radiator was rodded about 25,000 miles and a year ago.
It seems fine now and survived last summer in Atlanta, only time will tell. |

Hi, I have being dealing with a "mysterious overheating" problem for the past year now on my 95 Disco. I had the dealer clean and flow test the radiator twice. Then a new one was bolted on and it didn't make any difference. Also, the water pump, the t/stat, and the temp sensor were replaced. All fans checked out ok. After all that and a lot more work it ran hot only on a hot summer day or under a heavy load. Now, the temp gauge goes all the way up within minutes of start up, regardless of the temp outside. I checked the running temp around 175 degrees and the sensor is responding to the temp around 6 volts. I traced the 6 volts all the way back to the gauge. Any ideas, I'm desperate? |

Felix,
You may have a blown head gasket. Where it is not too bad, but bad enough where combustion can leak into the coolant and heat it up really fast. Did they do a pressure test on the whole system? That can tell you if everything is sealed. You can also pull the radiator cap and as the car warms up, if little bubbles start to form, you have a head gasket problem. Hope this helps. |

I had the head gaskets replaced last summer and the system tested ok, but now it seems like there are some traces of coolant coming out of the front part of the heads. I'll have to look for bubbles. Thanks a lot for your help, I'll let you know. |
