overheating issues

ok well ive had a small issue with overheating over the course of the last month. it comes and goes, sometime it will start to overheat than drop back down. the first instance i noticed this , i put my stock clutch fan in, and changed the thermostat as well as pulled the waterpump to check the condition it was in all was fine. however we thought maybe the car had something blocking the hoses so we tried the small return line and used an airhose on it. first second nothing, than boom seemed to clear whatever if anything was there.

sure enough a few weeks later it started again, now i have to mention when i put the heat on, it seems to help, however the air is cool than after a few minutes it goes to hot. i messed around with the system and i was good again

i go and get some work done on my car a week later(only put some gauges in EGT, oil pressure and wideband O2) after i left all was ok but i started to overheat again, when i stopped the car it told me check coolant level, now we didnt touch anythign on the cooling system but i opened the cooling system and checked the level later on and it seemed fine.

wtf, it seems fine most of the time but i cant keep my eye on the gauge all the time, it happens at idle and happens when driving ,there is no pattern

what to do next.

thanks in advance

Well.... most idle problems with heating are due to the aux fan relay.. as you probably well know...

As for while driving... the best idea I can give you... if the same problem I ran over a few months back... I did a re-do of my entire coolant system... and replaced the thermostate.... all fine and dandy... blah blah... then it started over heating... everything was fine... worked fine... then overheat again.... everything checked good...

Faulty thermostate was the problem... yes it was new... and yes I installed it correctly... but the problem was just a sticky thermostate... it happens...

If your coolant lines are free flowing... and your radiator is fine... along with your water pump... there are only two dertermining factors...

Faulty thermostat.... or... you have a passage flow problem. Which ten times to none is due to the gay plastic impeller eating it self...

Replace the thersmostat and see what she does....

Good Luck...
