You should be able to run a single 16" thermo no worries on the six so you can ditch the power sucker. Headlights get new ones the aren't dear about $70 of ebay for a pair same with the chrome trim keep your eye out for them on ebay they pop up every now and then.

thanks for that umm i just need to know the wirering part for the thermo do you know how to or dose anyone els know how to

wiring up a thermo fan is easy, just get a temp sensor and i can help you out with it if you want

[ari666]

meh, temp sensor. hard wire that sucker.

get a relay:



run
pin 85 to ground
pin 87 to the + terminal on your coil
pin 86 to the battery
pin 30 to the fan

the numbers are on the base of the relay. i would suggest getting a relay holder (narva part number 68084) because its neat and easy to change relays later if it goes pop, but normal blade crimp terminals fit.

you could hard wire it if you want it on costantly how ever if you want it to come on at a certain temp by itself you need to do it via a sensor
also if you follow your instructions you wont get it working

Pin 30 goes to the positive side of the battery or an acc wire so it turns on and off with the key, not to the fan
Pin 85 goes to the ground
Pin 86 would usualy go to the switch to turn it on but if you want it hard wired loop this to pin 30 so it gets power to it
Pin 87 goes to the fan
the other wire on te fan goes to ground, if the fan spins the wrong way just switch the 2 wires on the fan around

LMAO! i love how people on JC contradict you, just for the sake of contradiction.

Not just for the sake of contradiction, your wiring above was wrong


edit: not that the second version above is much better, if you wire both 30 and 86 directly to the battery the fan will never turn off

stick with the clutch fan mate, they shift more air than a thermo, disengage when not required, are more reliable, and actually draw LESS power from your engine (contrary to popular belief). If you do plan on running a thermo, remember that the power doesn't come for free. Your alternator has to generate it and your engine has to drive the alternator. So find out the current draw of the thermo fan, and then look at the output of your alternator. A good quality 16 inch fan (eg davies craig) draws close to 20 amps, blue 6cyl Commos only had a 45 or 55amp alternator, so combined with your ignition system and other accessories you wiil more than likely end up with a charging issue. For example, if you end up in traffic on a rainy day, with headlights, wipers and thermo fan blowing, your alternator won't be able to keep up - battery voltage is going to drop severely - been there, done that.... wipers almost came to a standstill and headlights went a dull yellow.

So you are probably going to need look at adding the cost of a higher output alternator (ideally 75amp), large gauge wiring capable of handling 20 amps or more, good quality electrical connectors or everything melts and you end up with an overheating engine.

that is why i wrote or ACC WIRE SO IT TURNS ON AND OFF WITH THE KEY, read all the post first

oh pooh. googled pic has the wrong numbers on it lol. sorry OP!!! i shouid've just looked at a relay.
need to swap numbers 86-87 over

while we are on the topic.. does anyone know if the standard temp sensor will provide enough resistance while cold to not switch the relay, i.e. bridge into the temp sender wire with pin 85, and use it as the relay earth?

[hypedz]

yes you can, i had this same set up on my old celica
