Radiator fan not working?

[Cookster]

Hi

Just got back from a months euro tour in my T25 done 3000 miles engine diden't miss a beat, haven't had it long so was a bit concerned she would make it OK it was an awesome trip done 6 countries saw some amazing sights, can't wait to go again!

Took some spares & joined ADAC but diden't need any of them.

The only problem we did have was that whilst queing for the St Gottard tunnel which is around 17k long she started overheating pulled over just before we enterd the tunnel and noticed water coming from under the engine, was a bit worried to say the least but it was only coming from the resivoir bottle so we let the engine cool down checked everthing, topped her up and off we went got a bit warm around venice as the weather was really hot around 45! but other than that she made it fine & done us proud.

I realised that the reason for this was the fan is not cutting in, I know some of you might think I'm a pratt but as I'm new to T25's and not that mechanicly minded I thought while she was running ok to leave well alone. Not sure weather it could be thermostat, electrical or the fan is just buggered.

Is there a fuse for the fan in the glove box as one of the fuses is missing? is there any common faults and what should I check to find the problem?

She an 84 model with a 1.9 engine.

Cheers

Chances are the fan switch has gone ... test the fan by bridging the thick wire to the switch with either of the other 2 wires ... 1 is fast and 1 slow fan (IF the early fans were 2 speed ?) if the fan comes on the thermoswitch is foooked ... available from Baxter

Sorry if I sound like a dumb ass but where do I find the fan switch?

Undo lower front grill and its the large brass nut with an electrical connector on it on the side of the rad..

Fans do "seize" with lack of use as there is an awfull lot of water in the system..

If in a long que.. try and switch off if it looks like you aint gonna move for a while.. no point in using fuel and heating it up..

In desperation/emergency you can turn the heater to hot and fan on max... need to open windows though... but on a hot day it can be a bit uncomfortable to do this...

Some early vans do have 2 speed fans (My 1983 caravelle does)

As above but in addition, mine wasn't working and traced the fault to the Rad Earth connection at the earth crown next to the fuse box. The spade terminal had cooked over time and fell apart.

could be your dalek cap on your expansion tank (not the tank behind your number plate) might need replacing as well.http://www.brickwerks.co.uk/index.php?p ... t&Itemid=6

but it was only coming from the resivoir bottle
