Hi
As per the title I bought the Toledo/1500 Cardboard Radiator Cowl set to trial fit to my 1975 1500TC.
This is not a complaint at the parts, just an example of the fit to my modified car with the battery in the boot.
My thoughts are for my car the battery side fits very well, and I will make a steel bracket to attach it to the wing since the battery is not there to support it.
On the Air box side, it’s in the way of the air box tubes so I will remove it and hopefully replace it with the “All Air filter pipe brackets and fibre boards” I bought from the club once the paint dry’s and I will add more photos.

I have never had any overheating problems with my 1500 Dolomites when they have been moving. They only overheat when they are in very slow moving / stationary traffic so I am sorry to have to say that I do not think having the blanking plates to force more air through the radiator will help to reduce any overheating problem because the car needs to be moving to get the air flowing through the radiator. I did make up some blanking plates but have since removed them as did not seem to improve the situation. I have also fitted a radiator which has more fins and I was assured this would overcome the overheating problem but it has not helped. The only way I believe to overcome the problem is to fit an electric fan which can drawer move air through the radiator and around the engine when the car is moving slowly or stationary.
The only thing that I have found that does help is if you popping the bonnet this does allow some of the heat to escape and so reduce the overheating problem.
I am currently considering removing the offside horn as I do not see the need to have two horns and I believe that the 1500SE only had one from new. This might help to increase the air flow down the off side of the engine and help to stop the fuel vaporising which I believe is the major problem when the engine starts to overheat. It would also reduce any possible damage to the horn switch as the current take though the horn switch would be halved. In all the years that my family has been driving 1500 dolomites I have only had to replace one horn switch in over 546,000 miles.
I would also like to suggest you check the cooling system pressure cap, on the expansion tank, is holding 13 psi as if it does not this can cause the engine to overheat.

Hi Guy
I think you have picked up the wrong end of the stick, there is no issues with the car, I just wanted to see what they look like and support the club.
Car always runs just below halfway on the gauge, and with the boards its the same, no changes.

Barry

Hi
Today I fitted "All Air filter pipe brackets and fibre board" from the club with some new 1-1/2in corrugated hoses and I am very happy with the out come. I will probably replace the fibre board with steel if it starts to fail (already copied it on to a bit of sheet steel so maybe cut it out and paint it in blue for the future.
I think it fits very well on my car, although I did have to slot out the mounting holes just a bit, but we all know no Dolomite is built the same!
