Hi all! i have a 2wd cosworth i bought september time last year. Noticed after a few days that the fans didnt start up when in traffic and nearly cooked the engine! So when i got the car back home i was told to run 2 wires direct from the battery to the fans and they went straight away, so ordered a new uprated fan switch from msd thinking that would cure the problem but went out last weekend in the car and noticed the temp gage getting high and couldnt here any fans so took it home left it ticking over and temp gage nearly went into red and still no fans. So took the plug off the fan switch and put some wire in to complete circut and the fans started so not sure what the problem is?? Ive heard that the fan loom is crap on the sierra cosworth but wouldnt what ive done above prove that its not the wiring?

Could i have bought a faulty fan switch? Dont think its the temp guage.

Would like to get this sorted as i plan on driving up to croft next sunday

Any help greatly appreciated

Cheers,Rick

 

Wire it up to a switch inside car

 

Yeh just like i have

 

Think thats what ill have to do but would prefer if it kicked in as it should.

Cheers,Rick

 

Best of running a seperate fly loom and do away with the existing, seems funny that it works when you short the switch out, theres a fella on e bay that sells them and paul at north yorks had one for sale in the cosworth section a while back

 

yeah wire a new loom..

just drop a fuse on the live cable to switch and then a new cable to fans...

ohhh and a nice earth too..

 

Thats what i cant understand if i short the fan switch out the fans start up. Do you think it could possibly be a faulty switch ive bought? Is there any way of testing it?

Ill have a look at running a seperate loom, Any idea how much these are?

Cheers for reply,Rick

 

heres pauls one for sale mate drop him a pm see if he still has it

all the bits you need.... prob just some more cable etc..

 

Nice one thanks for the replys

Dodgy imo to run with just a manual switch inside car, only needs forgetting once to be very expensive.
