hp006 Posted March 12, 2007 Share Posted March 12, 2007 Can any one help me???? I drove from London to Cambridge today and the temp gauge started to go through the roof. The temp gauge read normal whilst driving on motorway. I made it to my address and waited for the engine to cool when I then looked inside the radiator and it was bone dry. I toppped it up with water to see what would happen and then went round the block again. EMPTY. When i looked under the car there was a puddle at the rear of the engine bay, where i think water is running down. It looks as though water is coming out from where the manifold sits on one side. Does any one have any ideas??? I know it is hard to diagnose but i want to try and get an idea of price or if its something simply i could do myself. Thank you for anyone that may help.

Kranz Posted March 12, 2007 Share Posted March 12, 2007 Split hose??? Pipes that come out of the engine are throttle heater on inlet manifold, turbo coolant supply & return pipes and heater supply & return pipes. Fill it up and idle it until it gets hot and starts to build pressure. Then have a CAREFUL look round at all the pipes and give them a little wiggle. If its empty at the moment there should be white deposits around where its been leaking & dried. Link to comment Share on other sites More sharing options...

Didnt you think of pulling over quicker... and taking a look if the temp gague was going over the roof? Please take a picture of the area that you think the water is comming out of, Link to comment Share on other sites More sharing options...
hp006 Posted March 14, 2007 Author Share Posted March 14, 2007 I filled the radiator back up and left the car to idle. When i moved one of the pipes down the back of the engine the leak became a lot worse, more as though as i added water it came out the other side. I have taken the car to a garage and they said that 99.9% of Supra's that go in with a water leak it is the head gasket that has gone. Is this true? I can not add pics as the car is now in the garage waiting for a block test. And yes i did think of stopping sooner but the car was running at normal operating temp on the way up, it just fluctuated a little so thought i could sort the problem out when i arrived in Wisbech.

Jake Posted March 14, 2007 Share Posted March 14, 2007 I have taken the car to a garage and they said that 99.9% of Supra's that go in with a water leak it is the head gasket that has gone. Is this true? Yeah, on MK3 Supras not MKIVs Anyway, sounds like you've found the leaking hose, right? Link to comment Share on other sites More sharing options...
Kranz Posted March 14, 2007 Share Posted March 14, 2007 more as though as i added water it came out the other side. Reminds me of a sight I saw in India with a young boy perched on the front of a truck with a watering can..... topping up the coolant as it drove along At least you've found the problem. Doubt it will be head related, just need a new hose as these cars are getting old now and hoses do become brittle. Link to comment Share on other sites More sharing options...
