Well that's my next question answered as well! I run my 144's at 26-28 so that makes
sense. Fingers crossed it'll be easy for people to search out this thread and have the
basics covered. Thanks again.

quick tire question

Hi I'm sure this question has been asked 1,000 times so apologies, Am I right in assuming that a 155 tire will fit on a standard rim (on a standard 1962 car), and is it ok to have 145's on the front and 155's on the rear. I'm thinking this would be the best set-up. My problem is that I can get two 1...

Phew, I'll have to be careful mentioning the bypass system in posts again! I spent hours calibrating the temperature sender against a proper thermocouple type thermometer and a pan of hot water. I have driven the car quite a bit since my last post, down to Hertfordshire and up to Wolverhampton, and ...

Ooops, I have finally found the spec of the moggies charging system, the dynamo can produce something like 22Amps max (at 2,250rpm), but interestingly the 'compensated regulator' gives a high voltage. At 10oC it gives 16.1 - 16.7 Volts, at 40oC its 15.3 - 15.9V. The charging voltage should drop down...

I tried running the car with the radiator half covered (leaving the fan blades on for now) and it has confirmed that the thermostat is regulating the engine temperature nicely at 70oC, not 88 as I was expecting! I have ordered a new thermostat and hopefully this will give me around 80oC and give the...

I have just tried the vauxhall fan (off an old astra 2.0i GTE) and its drawing 10Amps. So if I go ahead with this I am going to have to be careful to get a small efficient fan. Certainly, anything bigger than 10Amps won't work. I am not sure how much current the dynamo can deliver but lights and a f...

Thanks Roni that's exactly what I am looking for! I think another trip to the scrappy is in order. I don't suppose you remember which Mazda the fan came from? I particularly like the way the motor isn't taking up too much of the dimensions of the fan allowing of reasonable air flow when its not runn...

Thanks MoggyTech, a quick adjustment to the regulator might be worth a go. The main reason I don't want to change to an alternator is basically I want to keep as many original features of the car as possible whilst keeping it as a daily driver. Obviously things like heated windscreens (which would d...

voltage regulator / electronic cooling fan

Hi – I am an electronic engineer by trade and for a little home project I put together a little digital gauge that shows battery voltage, engine temperature, rpm. Eventually I will add a beeper for the indicators (to stop me leaving them on) and a warning buzzer when the lights are left on (for the ...

I am sure it is possible for the block to warp, but in my experience it is always the cylinder head that goes out, normally as a result of overheating.

I am sure lots of people have advice on alternatives that will give you a little extra power, what type engine is it 948cc or 1098cc?

I concur, sounds like head gasket to me. The only way to be sure is with a compression test. Changing a head gasket isn't difficult (find a workshop manual), however your head might be warped so you need to check this with a steel ruler or something. If isn't flat it will need to be machined, or if ...

New springs made a huge difference to my car. Mine looked pretty much like that for ages and the car drive OK. It was only when one finally cracked that I changed them.

You sometimes get a 'sweet smell' from an electric motor getting too hot, in your case the wiper motor would be the one to suspect. However it will have to be pretty warm to do it, definitely hot to touch. Personally I think the problem is most likely antifreeze or a result of the cleaning. As for y...

Update - well some time has passed and the problem reappeared.

Thanks for all the help. The problem was surprising easy, I replaced the rear springs two years ago, and the rubber bushes under the U bolts had perished a little making the nuts loose, not falling off, but the needed half a turn. Tightened them up and hey presto, noise has all but gone (well its ab...

Thanks bigginger, Ok, I will probably drain the coolant and remove the heater valve, (has been off a few times doe to the old one not working and the replacement not being very good) and well take it very slowly.

I was flirting with the going down the EV route with my moggy
a while back, though I never managed to raise the money to
do it. I am surprised you need the gearbox but you've obviously
done a huge amount of research into this.

In all good luck with the project!
