Allienmass Posted May 12, 2015 Share Posted May 12, 2015 Right iv had a new subaru coolant temp sensor fitted which has sorted my coolant fan prob so they do switch off now, but the temp gauge on dash still isnt right, maybe worse than before, it still sits too low during driving, wen i pull up to junction it seems to dip abit and when i turn on the heater fan in the car that effects it aswell :( realy dont know wot to do now :( I had a new rad fitted, prob wasnt a oem one because i thk my mechanic used his normal motor parts dealer, could that be cooling the engine better than the old one ? when it was taken out it had bowed at the sides which was weird, and had a tiny leak.

Allienmass Posted May 12, 2015 Author Share Posted May 12, 2015 Could all this be down to air in the system because iv always heard its hard to bleed the system well ? Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 12, 2015 Author Share Posted May 12, 2015 And i can smell coolant under the bonnet somtimes wen hot but the levels not dropping atal ? Dono if thats normal ? Quote Link to comment Share on other sites More sharing options...
stants Posted May 12, 2015 Share Posted May 12, 2015 Hi mate glad you got the temp sensor sorted but not good about the other possible issues, I wouldn't worry about the rad being non oem loads of motor factors sell replacmemts as subaru rads a weak and distort and split on the ends like yours did , easiest way to check for air is to run the car for a bit check each end of the rad and the bottom hose if one side or the bottom hose is cold then you'll need to bleed it more, What does your temp gauge read when warm ? The coolant smell could be just a spillage and as it's boiling point is around 230°c it's still sitting on the block or undertray. How full is the expansion tank on the right when cold ?

Allienmass Posted May 12, 2015 Author Share Posted May 12, 2015 Jus went out for drive to get pics and test the rad, yeah rad hot both sides and both pipes hot, expansion tank is at max wen cold then goes bout inch n a half above when hot. I will send a pic of gauge Quote Link to comment Share on other sites More sharing options...
stants Posted May 12, 2015 Share Posted May 12, 2015 Ok well maybe the coolant you can smell is being forced out the expansion bottle when hot, the level should be on min when cold and around the max mark when hot Quote Link to comment Share on other sites More sharing options...

Allienmass Posted May 12, 2015 Author Share Posted May 12, 2015 It never used to sit dead center, it sat jus below, but not that low, i we are only talkin a few mm lol Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 12, 2015 Author Share Posted May 12, 2015 Hmmm okay i will take out abit then :) could that be the sorce of all my probs lol Quote Link to comment Share on other sites More sharing options...
stants Posted May 12, 2015 Share Posted May 12, 2015 I wouldn't worry too much mate, I put a new rad in and changed the coolant in feb for some longlife stuff seems to be more effective at cooling as my needle now sits a fraction lower and I don't get as much coming into the expansion bottle. Of your worried just keep a small mixed bottle of coolant in the boot and keep an eye on it, or if you're got an android phone get a Bluetooth dongle and the torque app then you'll be able to measure your temps a bit more accurately Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 12, 2015 Author Share Posted May 12, 2015 Hmm hopfuly its nothing then :) Does your temp gauge move much when driving around or is it solid when up to temp ? Quote Link to comment Share on other sites More sharing options...
stants Posted May 12, 2015 Share Posted May 12, 2015 Stays solid, I've plugged in the diagnostic software I have and it reads about 86-87° which sounds about right Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 13, 2015 Author Share Posted May 13, 2015 Lovely :( drove to work and the fans are not cutting out again, im gona try burping it again 2nite, should i completely drain and start again or can i jus try it again ?

Allienmass Posted May 13, 2015 Author Share Posted May 13, 2015 Could there be air in it still even tho both pipes get hot n stuff ? Quote Link to comment Share on other sites More sharing options...
stants Posted May 13, 2015 Share Posted May 13, 2015 Maybe intake it your getting warn air into the cabin ? Easiest way to burp is either jack up the front of car, or park uphill. Get a helper makes life so much easier while they squeeze bottom hose you keep an eye on the header tank (do newage have them ?) Check for bubbles and top up as required Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 13, 2015 Author Share Posted May 13, 2015 Header tank is that the silver tank near the turbo ? Yeah got warm air in cabin, its not great tho and sometimes i feel its not hot enough Quote Link to comment Share on other sites More sharing options...
stants Posted May 13, 2015 Share Posted May 13, 2015 Yep, wasn't sure if the newage had same set up. Worth a go at re bleeding. Have you checked the ecu codes for any faults ? Quote Link to comment Share on other sites More sharing options...

Allienmass Posted May 13, 2015 Author Share Posted May 13, 2015 Yeah no faults :/ on that pic wen it says rad cap does that mean the header tank cap ? How long hav a got be4 the pressure goes up ? Wont the fluid go everywhere wen caps off and engine on ? Quote Link to comment Share on other sites More sharing options...
stants Posted May 13, 2015 Share Posted May 13, 2015 Yes rad/header same difference, with the cap off it won't build pressure so it won't go everywhere Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 13, 2015 Author Share Posted May 13, 2015 Okay cool i will giv it a go :) iv got a cap on the actual rad aswel should i take that off aswel ? Quote Link to comment Share on other sites More sharing options...
stants Posted May 13, 2015 Share Posted May 13, 2015 May be worth opening that one and topping off and putting the cap on the rad as the bubbles will come out of the highest point (header tank) Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 14, 2015 Author Share Posted May 14, 2015 OMG, jus got home from work and noticed that me turning my lights on and off also affects the coolant fan speed, is this a big electrical prob iv got :( could my mechanic have wired the fans wrong ? Havnt had a chance to burp it again but think thats not the prob now :/ Quote Link to comment Share on other sites More sharing options...
stants Posted May 14, 2015 Share Posted May 14, 2015 Sounds like it, [emoji26] a bad earth or something,do both fans come on when you use the ac ? Quote Link to comment Share on other sites More sharing options...
Allienmass Posted May 14, 2015 Author Share Posted May 14, 2015 Yeah both come on when ac is on, both are on when fan is on high and low speeds. I thk im gona have to book it in with a subaru specialist :( Quote Link to comment Share on other sites More sharing options...
