Yes, if you cool the coolant faster than a stock fan will you'll have a cooler engine. Don't expect to the temp to go under 82deg celcuis though. As the thermostat won't allow it. If the systems too efficient it will drop below 82Truffles said:My XD 351C (on gas) is not liking the warmer days, but I'm not sure if more airflow will help.
*puts on the noob hat*
Currently the radiator and stock fan seem to be doing a great job, in that a LOT of hot air comes off the radiator. I'm not sure of the science behind it, but it seems to me that blowing hot air into the engine bay is a bad thing.
The engine is tuned (although it needs colder spark plugs and leads, which I'll be getting shortly), the radiator is a new 3 core, the thermostat is new (82C). So will sucking more air through the radiator fix the problem?
I'd like to be able to use the aircon on hot days, as currently I'm in the ironic position of only being able to use the aircon on mild days, where winding down the window would suffice anyway.
Your only get the fans. As the wirings all custom for any other car than an AU. You have to custom do everything (wiring,replays etc).351xd said:when you buy a set of AU thermals do they come with all the necessary stuff to connect to an xe or do u need to go and buy any connectors, wiring etc?
Rhett I am thinking of going down this route as well and I assume you used these: http://www.rsaustralia.com/cgi-bin/bv/browse/[email protected]@@@[email protected]@@@&BV_EngineID=cccdadddfkdflhlcfngcfkmdgkldfih.0&cacheID=auie&3280478448=3280478448&catoid=-83768476 not these:http://www.rsaustralia.com/cgi-bin/bv/browse/[email protected]@@@[email protected]@@@&BV_EngineID=cccdadddfkdflhlcfngcfkmdgkldfih.0&cacheID=auie&3280478410=3280478410&catoid=-83762356I picked up 3 little switches from RS Components in Osborne Park that close when they reach a specific temperature. They only cost about $8 each and I’ve mounted them all to the top of the radiator near the top inlet. A 60C switch activates one fan, a 75C switch turns on the other fan, and a 90C switch is connected to a reversing alarm to let me know that something is wrong before I go cooking my precious 351.

and used normally open ones. Similar (but cheaper) ones are also available from Jayacar see: http://www1.jaycar.com.au/productView.asp?ID=ST3836&CATID=&keywords=thermostat&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=
I used shallow self-tappers and mounted them to the frame of the radiator. Be VERY careful not to touch any water passages. Mount as close to the heat source as possible, ie near the top hose (where the heated water arives from the top of the block) or you can make up your own little brachet and mount it on the motor somewhere. I like the top of the radiator because it is easy to get at and it's easier to hide the wiring.GreenMachine said:Where are you guys mounting these switches? Are you tapping threads in to the rad?
They measure the temp thru their butts, so make sure you mount it to a flat surface. Be careful when drilling the holes, because if they are a little too close, the screws (when tightened) will cause the base to arch up away from the surface of the radiator.GreenMachine said:So they don't actually need to probe in to the rad or anything? They measure the temp on the outside?
Mine are like this, came from an EF. They do a fine job, ive got a 2 core XF rad in my XA with these fans. They do pull some power tho, when they come on it drops my lumpy 9-800rpm idle down to very lumpy 5-600 rpm idle.grey_esp said:Im thinking these arent EL fans tho. They are not offset like au fans, but each fan only has 2 wires, no white wire as mentioned in an earlier thread.
Well the Jaycar one is still working is but the RS ones have now died. But yes they are the ones I thought you meant and the Jaycar ones are similar. Bi-metallic thermostats and not the RS thermal switches part no's 307-929 and 307- 935The links aren't working Aussiblue.
