ibby Posted December 27, 2013 Share Posted December 27, 2013 i generally lift the front of the car up / park it on a hill and start it. just check for bubbles Quote Link to comment Share on other sites More sharing options...
Big Supes Posted December 27, 2013 Author Share Posted December 27, 2013 Just run it, it will self bleed if everything is working as it should. Just keep one eye on the temp gauge and check the level in the rad and expansion tank when its cool. Rad should be full to the filler neck, check the hose from the rad neck to the expansion tank is okay, i had one that had a little split in it a while ago and let air get drawn back into the system. I've been running it for a while hoping it would self-bleed, but every now 'n then I hear the radiator bubbling after shutting down the engine. I'll have another look over the coolant hoses to make sure there aren't any splits. Regarding the temp gauge, are they reliable? The gauge on the 200sx was nothing more than a indicator (on all cars) to tell you when the water was up to running temp. It would only move slightly above half way when the engine was nearing melting point. Since then, I've never trusted them. i generally lift the front of the car up / park it on a hill and start it. just check for bubbles That did cross my mind. I was thinking about jacking it up and pushing my ramps underneath. I was just wondering if there was a technique... I remember on the Celica you would clamp the top pipe, get it up to temp, then release it and all the air would come bubbling out. Does anyone know if anyone supplies a silicone top hose with an in-line bleed nipple?? Quote Link to comment Share on other sites More sharing options...
ripped_fear Posted December 27, 2013 Share Posted December 27, 2013 Had this before. Try rad cap first, first time this cured it for me. Quote Link to comment Share on other sites More sharing options...
Big Supes Posted December 27, 2013 Author Share Posted December 27, 2013 Had this before. Try rad cap first, first time this cured it for me. No harm in ruling it out. I could throttle whoever didn't tighten up the top hose in the first place. Quote Link to comment Share on other sites More sharing options...
Dnk Posted December 27, 2013 Share Posted December 27, 2013 I've never had to mess about jacking them up or parking on hills, is it getting hot enough to open the stat ? 82 c i think is stock stat opening temp. Take it for a drive. No idea as to how accurate the temp gauge is but my uk car never went above half way If its still the original cap bin it and fit new Quote Link to comment Share on other sites More sharing options...
Big Supes Posted December 27, 2013 Author Share Posted December 27, 2013 Yeah, it seems to be getting up to temp, but to be honest, I don't really have a lot of faith in the stock water temp gauge. Maybe I'll pop the thermostat out and check it. Will get a new rad cap on order... Quote Link to comment Share on other sites More sharing options...

Benjy Posted December 27, 2013 Share Posted December 27, 2013 The temp gauge never goes above half way in any supra as far as I'm aware. They're fairly reliable as it's basically a variable resistor. If it gets hotter, the gauge will start creeping up. Leave the cap off over night. Top it up in the morning and let it idle with the cap off. Put the blowers on hot but keep the fan switched off. Only use the blowers every now and then to check the heat inside the matrix. If it bubbles over, knock it off, let it cool down and top it up again and start from the beginning. Keep an eye on the gauge and the top of the rad. You'll be able to see the bubbles. Occasionally give it a little blip of the throttle if it doesn't spit any bubbles out for a while. And fit a new rad cap. Quote Link to comment Share on other sites More sharing options...
Big Supes Posted December 27, 2013 Author Share Posted December 27, 2013 Cheers, Ben. That's pretty much how I went about bleeding it the first time around, but I can't seem to get the last bit of air out. I'll give it another try tomorrow and take the rad cap off this evening as you suggested to see if that helps. Toyota have a cap on order for me.
