If however, this does not solve the problem, you may have a damaged line somewhere causing a leak (which would cause air bubbles as well). in a previous post, you mentioned your vehicle overheating, may have damaged some hoses? anyways, we'll start with the easy stuff first and take it from there.

Regarding the fan, I've only ever had one go bad. It made nasty-loud whirring sound and was pretty much frozen stuck solid no matter what temperature the engine was at, but I don't think it was overheating - but I also think the owner never drove it hard with that loud whirring noise (if I recall correctly - it was a number of years back). We replaced the fan's clutch assembly (moved the blades from one to the other), and it fixed the whirring noise. Is your oem fan shroud still in place? How about the thermostat - is that new? ...and is it oem-spec? Reminder: No one should ever be doing work on the Mkiv Supra Turbo's powertrain without a copy of the Toyota Supra Repair Manuals (TSRMs). I'm sure there's a test for the fan in the TSRM, as well as a complete diagnostic procedure for overheating.

i drained the powersteering and bled it with new fluids.
oem fan shroud is still in place.took the thermostat out thought it was the fault but it was not that.thermostat is still out. I looked in the TSRM but they dont say anything how to test the fan. Wen i drive normally the heat gauge is half as soon as i boost her the heat goes up wen i drive normal again the heat goes down. |
