Hi all new here,I have a moonstone blue saffire 2wd , every time I drive it the fuse for the cooling fans blow , anybody any ideas , thx lofty in sunny belfast ...

 

common fault is that the actual fuse box wires may have melted or the switch in the rad maybe knackered!

 

Yes rewire the fans!

The original wiring was sub standard from new, leave alone now!

In your case it sounds like a short as the fans do not run unless they are needed, in traffic etc (I woulden't keep replacing the fuse as it's blowing for good reason) but there is no point in wasting time trying to trace the problem as they need rewiring anyway!

If you do a search on here there are plenty of threads with diagrams, you can either buy looms pre made or DIY.

Another weak point is the fuel pump wiring, with age it builds resistance, so the fuel pump cannot draw the power via it that it needs, this can lead to an engine meltdown, again a rewire is the remedy or you need to check the voltage present WHEN under load.

The reason the fuse melts is due to the terrible span of the switch that is fitted, thus the fans stay on for far to long causing the wiring etc to heat up.

thx guys , i did change the fans cause i had a spare set , so i know its not them , i will try the rad switch next , if not then the wiring . today she has also developed a very bad misfire . this is all after spending 3k on an engine rebuild , o the joys lol ..............

 

Won't be the rad switch, that merely completes the earth circuit, so there is no way at all that is the cause of the problem!

As I say forget the original wiring, it needs rewiring regardless!
