Yep, completely agree with Steve as well Raf. Sam, Binnys rad came from the same bloke so it will be the same as DTR. I have one coming from GAT Rads with the help of Alun, he says the old chap knows his stuff and I trust the old man, Alun that is! Lets keep the hot weather coming so I can test it! |

Let me know how you get on with the replacement rad - I might have to consider the same route for Binny.... I'm not sure my heart can take the stress of constantly watching the temp gauge all the way round the RBRR! |

So back to the heat! It's around 33 degs so I ran the car down the M3 and back, about 25-30 miles or so in the traffic at various speeds up to a good 80 or so. Temperature gauge was well under 3/4 and the car felt happier and the heater was off. So given the temperature I would expect some expect needle movement and this is now acceptable to me. Coming off the motorway onto 50/60 mph roads and the needle dropped to just over half way, quickly as well. I'm happy with that. All I need to do now is to set the temperature that the fan cuts in. Currently if I'm on the motorway it will be constantly on, so I think I have it set to come on at too low temperature. I think if I set it to come in when the needle is closer to 3/4 then it would probably just cut in and out rather than trying to get the engine temp back down to half again. Have to have a think about it. |

This might help? |

Thinking about electric fan activating temperatures, I would throw caution to the winds and have it come IN at 3/4 on the guage and drop out again a tad OVER 1/2! An electric fan controls the temperature MUCH more accurately and reliably than ANY sort of engine driven fan can ever do. So you don't NEED the margin of error that is built into engine driven systems and can AFFORD to let the motor run hotter (and therefore more efficiently) than would normally be the case with a standard car. You just have to overcome the personal paranoia that is the birthright of all Dolomite enthusiasts! An electric fan fitted car will display a much wider range of readings than a standard one (where the aim is "rock steady in the middle at all times") You just have to get used to the fluctuations, difficult as that is!

Thanks Steve! Alun has mentioned that hes not too happy with the temp readings given the size of the new rad. This morning I tested the voltage stabalizer and it reads a solid 9.8 volts output. I have sourced a NOS Smiths one which I will test for comparison. As for the temperature sender, it is a new one from Robsport. I have also been able to source a new old stock correct Smiths one from eBay (for NWL actually!) so when it arrives will be able to do a comparison. Tony will have to tell me how to do that!! |

The TR7 came with AC as an option in the US Mahesh, have a look at that.Quote: Rather more expensive, but permanent, is to put a set of louvres in the rear end of the bonnet! This will improve airflow through the rad, combat vaporisation by giving the hot air that would normally accumulate around the carbs an escape route and even help clear the screen on frosty mornings!
And they look cool!I have a spare bonnet that has a small rust hole in that area, I'm going to give them a go! |

As per my Facecloth post, do consider your spark plugs. Cooler running plugs made a huge difference to my Sprint. I think the standard NGK plug usually listed is a BP6EFS but I used a BP7EFS which is closer to the original spec in terms of heat range. |

Currently it has BP5ES' in it, which is fine for a lot of short town driving but out on the motorway it could be a bit too hot so switching out to a 6 or even 7 as you say may help. It's a cheap easy switch so I cant see the harm in giving it a go! |

A 7 is too cold. Jeroen |

So a 5 is too hot, and a 7 too cold, a 6 should be just right, (couldn't help it) Saying that my car seems to prefer NGK BPR6EFIX10 Iridiums over standard. |
