Guest gzaerojon Posted June 7, 2006 Share Posted June 7, 2006 the soops all running but i have a major problem with the coolent system, i just took it for a spin and came back, bonnet up to see if everything ok and the large radiator pipe feels pumped up solid, im a bit worried just to give you an idea of what happened to the car last time i used it i have gone bling, so have replaced the inlet manifold and tb, also all turbo pipes and boost hoses, all vacume hoses and a bling overflow tank. the temp while running is just above half way mark any ideas? i need her running by tmrw eve to go up to turbofit Quote Link to comment Share on other sites More sharing options...
supra matt Posted June 7, 2006 Share Posted June 7, 2006 sound like an air lock mate Quote Link to comment Share on other sites More sharing options...
Guest gzaerojon Posted June 7, 2006 Share Posted June 7, 2006 if it is, how would i sort it? Quote Link to comment Share on other sites More sharing options...
Scooter Posted June 7, 2006 Share Posted June 7, 2006 once cooled maybe try it idling with the rad cap at the bleed/half way position and see what happens? Quote Link to comment Share on other sites More sharing options...
Scooter Posted June 7, 2006 Share Posted June 7, 2006 or if an airlock maybe run it without a rad cap at all for a bit......... could raise the front of the car too...... =this might be a bit extreme though Quote Link to comment Share on other sites More sharing options...
supra matt Posted June 7, 2006 Share Posted June 7, 2006 put heater in car on hot and fan on full . take rad cap off but be carful as it hot and under pressure can be dangrous! as you will get coverd in hot water. then let it run till up to temp hold it about 2000 rpm for a min . that should sort it mate Quote Link to comment Share on other sites More sharing options...

Guest gzaerojon Posted June 7, 2006 Share Posted June 7, 2006 can a water system get this amount of pressure from an air lock? im praying its not the head gasket, i cant see how though as it was perfect before it went in the garage, and i've only done a couple of miles since it was finnished Quote Link to comment Share on other sites More sharing options...
paul mac Posted June 7, 2006 Share Posted June 7, 2006 i cant see a problem here mate you say the temp is reading normal, the top radiator hose will be solid (and hot) when you have warmed the engine up dont forget the cooling system is pressurised this is how it stops water that is locally (round the exhaust etc) hotter than 100 degrees from flashing to steam (very bad) so when you stop the engine obviously you still have pressure in the system till it cools down, i have had my cooling system drained down several times and never experienced any bleeding issues Quote Link to comment Share on other sites More sharing options...
Guest gzaerojon Posted June 7, 2006 Share Posted June 7, 2006 it has cooled down a little now and the pressure has dropped very slightly, but it just doesn't seem right for that top pipe to be that plump (for want of a better word) also it used to take ages to get up to normal running temp, but i started her up, about 1 min later started to pull away and notice the gauge already showing just over half way. i might just be a little over worried as i had an rs turbo (i know lol but i was young) and this had a simular problem where it pumped up the system and this turned out to be the head gasket leaking from a bore into the water system. where would i find the thermostat btw?

Guest gzaerojon Posted June 7, 2006 Share Posted June 7, 2006 could you take a picture of your "plump" pipe follow the bottom hose up to its housing and that is where the stat is thanks Paul, i'll have to leave till the morning now as i lost the light but will follow up tmrw Quote Link to comment Share on other sites More sharing options...
Supra ST Myster Posted June 7, 2006 Share Posted June 7, 2006 Sounds normal doesnt it? When i had a pipe, it got soild when car was warm, then about and hr or two you can then squeeze it again, system just gets pressurized when hot. Quote Link to comment Share on other sites More sharing options...
terribleturner Posted June 7, 2006 Share Posted June 7, 2006 Jon the thermostate i belive is on the turbo side of the car behind the water pump. Excuse the picture but incased in a bit of pipework which is in red. Yellow is where the stat lives. The ssame plaace as where Paul says but coming from the other direction You could have a quick go at flushing the system out. Otherwise drive it up and take it easy and keep an eye on the temps.

Guest gzaerojon Posted June 7, 2006 Share Posted June 7, 2006 cheers guys, i'll have another look tmrw, i'm starting to think its just me Emin how pumped up would you say they get when warmed up? like a bicycle tyre? cheers james, looks like a bugger to get to, there's probably nothing i can do with it without unbolting stuff, i think i'll start it tmrw with the cap half turned and the heater on and see what happens Quote Link to comment Share on other sites More sharing options...
Lucifer Posted June 7, 2006 Share Posted June 7, 2006 Its not too bad from under the car but MAKE SURE you disconnect the batter as the Alt Main cable is right next door. Quote Link to comment Share on other sites More sharing options...
Supra ST Myster Posted June 8, 2006 Share Posted June 8, 2006 noticed mine got a bit inflated from origanal size but nothing really noticable, but was rock hard when you try and squeeze it after a good run. Quote Link to comment Share on other sites More sharing options...
Guest gzaerojon Posted June 8, 2006 Share Posted June 8, 2006 ok i just started it again, it got to running temp in 2 mins, heater red hot. i just had a word wit Greg at turbofit he said its not right, also im now leaking drips on the top pipe because of the pressure so we're going for a jammed thermostat, so when it cools in taking the stat out and leaving it out thats the only logical thing it can be Quote Link to comment Share on other sites More sharing options...
Guest gzaerojon Posted June 8, 2006 Share Posted June 8, 2006 all sorted now, it was a dodgy thermostat that was causing the problem, so i've launched it for now and im running without it as long as i get to turbofit they can fit a new one and check it all out thanks for all your help guys Quote Link to comment Share on other sites More sharing options...
