    Red face wrx overheating :( help

    hi i recently got a new car its been fine for the first few weeks but blew a top hose ive replaced that and its blew it again also has a slight leak from the stat housing. i have had a chemical test done on the water system and no signs of head gasket runs good aswell, ive noticed if i turn the ignition on the coolant fan cuts in and out and when it is running the fan cuts in but very slow, also its a import and i think someone has changed the clocks as they dont seem to say the right speed in mph would this have anything do do with it or does anyone know what this problem could be?

    thanks

    Did you run a car fax on it? That will tell you where it came from.

    When my car is idling, the fan constantly turns on/off - even when it isn't that hot outside, and the car runs fine.

    Do you have the right coolant in the car? If you have a leak, you need to get that repaired, otherwise you will never be able to keep the proper amount of coolant in.

    First off crawl under the steering wheel and look up under the dash to find the green test connectors. Unplug them.

    Then you need to burp your cooling system - hopefully that will take care of the overheating.

    The green connectors put the car in diagnostics mode and makes the fans cycle when you have the ignition on but the car's not running. They have to be unplugged.

    Sorry - I just re-read your post, I thought you said you "thought" it was an import. I suggested Car Fax so you could find out where the car came from and its history.

    Sounds great, what are you putting on? Subi's can be touchy about their mods

    planning on getting new headers decat it has a slight air leak from the dump valve so i have a new one of them, not quite sure what its boosting at because its leaking someone has put a k & n kit looks like they got it free with tokens out of a cornflakes box...

    my friend said you can get a sti ecu and injectors and it will increase the bhp by 100bhp but i dunno how much truth there is to that

    ??

    Yeah getting all the leaks taken care of can go a long way. They are very finicky about the intake - the stock one works well. We don't mess with changing the ECU, just flash a new map suited for the mods if you do the cats etc.

    100hp is a lot without a turbo upgrade I don't see it. Turbo, IC, injectors, fuel pump & new map for that.

    The green test connectors should stay unplugged?
