Hi. I'm a new member and pleased to have joined Club 80-90. I have an 88 1.7 diesel hi-top. I recently had the head replaced and she seems to be running hotter then she did before (about half way). The fan wasn't kicking in so I tested it, changed the senser, bled the system etc. Now the fan kicks in only when the needle is getting near the danger area. I want to put in a manual fan switch - mainly for peace of mind. How is it best to do this?
We have done this.
Run a fused live supply to the live side of the wiring to the fan. Break this wire,you have fitted, with a switch and you have manual control and because the original wiring is still in place it will work with sensor as before.
You could just connect up to one speed either the high speed or the lower speed I don`t think this would cause any damage to the motor. Other folks may come along and verify that.
You should swap out your temperature sensors on the engine before inserting a manual switch and get the engine tested for compression and leakdown, otherwise you're likely to be attacking the symptons, not the cause.
All this was done when new head and gasket fitted. The needle sits just to the right of the led generally, on hills it'll creep up, on steep hills she seems to get really hot (past 3/4 on temp gauge) before fan kicks in. Should I be worried or is this about normal?
I would rather have what you have got ,with the gauge moving as the temp increases or decreases,mine moves about 1/3 up the gauge and stays there,makes me wonder if it's OK.
I would be well happy with that and would say that is quite normal.

Having reread the post Suk.I agree with you,thats not right.

Or a buzz bar the switch from a frankenstein movie. Hey that would suit our brummy friend 'Oldiguana' well, he's building a hybrid T his end - bits of this and bits of that. Just ribbin' you our kid
