    Default is having no temp sensor bad?

    hey, just a quick question, i damaged the temp sensor on passenger side head when i was installing extractors its a ls1. and i have ordered a new one off ebay but it hasnt arrived in time and i may have to use the car tomorrow for an hour drive or so. i took it for a quick spin the other night after i had installed the extractors and an engine warning light came up and thermo fans were on constantly but temp still got up to half on gauge. any advice would be great thanks guys.

    i assume it would be mate, because your car will think it always hot, therefore having your fans on.

    I thought they only turn on when it gets hot, so if the sensor is rooted it wont tell the fans to switch on....

    Yes, yes it is.

    lol, look if you need to pop round to the shops, or 20 mins to work, you should be fine. As long as you avoid stop/start traffic, and keep air flowing through her, it should be ok. Just don't delay installing the new one.

    Regards,

    The sensor looks at coolant temp and uses that for a range of things. One of these is turning the cooling fans on and off. Get it fixed ASAP, and until then the fans will default to on.

    ok guys, sorry i havent replied i rang my local holden dealer and talked to a mechanic. so basically it does what sabbath said, turns the fans off so if it isnt working or there isnt one they are on constantly. so if i were to drive somewhere in excess of 50kmh the incoming air would work against the thermo fans and i would be up for $600 for a new set apparently! so i flew straight up there in the work ute and bought one for $42 trade price. thanks for the replies guys.

    oh and if anyone needs a coolant temp sensor now i have a spare!
