Jimny hot running issues...

Long time no post...I do still have my Jimny, but in more recent months it plagued by consistent but irritating hot running. Only runs hot at speed (over 65-75, any less and its totally fine), when off road at slow speed and when idling for extended periods. It can be controlled and will run all day fine if the heater is turned up to the max and blasting at full speed. I have tried to remedy this several times. It has had in the past 12 months a new head gasket, new rad, new thermostat and just last week a new water pump. I'm starting tow wonder if its really worth continuing to pour money into this problem. I am seriously considering selling it if I can't sort this hot running our once and for all. I do not really want to do this, as I have spent lots of time and money on my Jimny over the past 2 years, but I am getting sick of pouring in money to not get results. I've been told that the viscous fan could be not working effectively, is there anything else worth checking/changing before I take the route of selling it? Any advice really is appreciated...

Travelling at speed the viscous fan wouldn't be engaged....unless you have too little airflow through the radiator.

If turning the heater on makes the overheating manageable then you have a lack of liquid flow through the radiator, lack of airflow....headgasket failure or a cracked head......or a lying temperature gauge/sender.....test for each and you're done....you get 45 minutes to check it all out....or you're sacked!

Cheers...hows best to check the temp gauge isn't lying to me? If its been that all along then there will be a very Basil Fawlty style moment...

Thermometer....I have a contact one.....must get myself a non contact one. also check the thermostat.......the heater circuit works independent of the thermostat.

And remember....halfway up the forearm counts as zero!
