sprag5 Posted June 16, 2009 Share Posted June 16, 2009 I took my radiator out today as my new one is coming at the end of the week and am fitting a TRD thermostat as part of the job! Looking at part diagrams and threads on here i am assuming that i follow the bottom radiator hose back and its casing is there, but i had a quick look and it seems to be buried deep into everything! Which isnt good as this is the first major job i have done on the supra! So all i am wondering is if there is anything i need to take out to gain access better as i would like to do this whole job myself.

JustGav Posted June 16, 2009 Share Posted June 16, 2009 Do you mean the 1.3 bar thermostat on top of the radiator?? Quote Link to comment Share on other sites More sharing options...

Homer Posted June 16, 2009 Share Posted June 16, 2009 Is the rad in as-new condition (and I really mean that), otherwise, it'll split. If you want to go this route you'll need to change the rad cap to a 1.3 bar one as well, otherwise you're asking for trouble. There are many, many threads here about split stock rads when raising the water pressure, usually due to replacement 1.3 bar rad caps, but the termostat is going to have a similar effect.

pedrosixfour Posted June 16, 2009 Share Posted June 16, 2009 Take out whatever you need to do the job mate, some jobs are easy, some jobs will have you close to tears. Others you have to make the tools to complete the job, don't forget that engines are first assembled on a production line with access from every angle and no thought is given over to ease of maintenance in the ensueing years Thats mechanics for you.

sprag5 Posted June 16, 2009 Author Share Posted June 16, 2009 I have bought a brand new radiator and the stock radiator cap apparently fits it so hoping to keep the pressure at stock levels for fear of popping my heater matrix But what i cannot see is where the thermostat is located as it seems to go into a tangle of wires and pipes underneath the turbos (Thants if i am looking in the right place). I was just wondering if any one has any advice on how to get into the location a bit easier, maybe by removing the air box or by removing the intercooler pipe. I just dont want to have to take parts out that i dont need to Thanks Quote Link to comment Share on other sites More sharing options...
bignum Posted June 17, 2009 Share Posted June 17, 2009 Its easier from under the car, the stat is in the alloy elbow type thing where the bottom rad pipe ends, a long extension bar with a bendy on the end will do it. Quote Link to comment Share on other sites More sharing options...
