Is it okay to run a thermo constantly

[VR_Acclaim]

hey guys my thermo only kicks in some times ive tested it and it run perfectly off straight power. So i was wondering if it would be ok to run it directly off an acc power source so its constantly on,,of course ill fuse it and relay it but will it be fine for a quick fix until i get paid i have done it before on my vp and it ran fine for 2 years.. so will it be ok

your thermo will be fried alot sooner than its expected life if you do.

what's the problem with the thermo at the moment, they kick in at a cirten temp 109 deg c and switch of at around 100 deg c and only runs below 40km/h and of corse when the a/c is on. there are many vr's getting around with misleading gauges and also blocked radiators, maybe a good cooling flush and possibly a new thermo stat.

flushed it today and it runnin a quater driving and the temp goes down very slowly while driving...i got a vs down stair that has a 3 weeks or so old thermostat are they the same?? its only gotten hot since i flushed it out 3 weeks ago done it again today with decent coolant and deminralised water and its still doing it.. any idea what it could be

You may have a blocked radiator of an incorrectly reading temp gague.

If you have acess to a scan tool, you can read the engine temp from the coolant temp sensor rather than the gague sender.

You may have an air lock if it only started after the first flush.

get a new radiator

or run the fan i did it in my vs for 3 years never had a problem

[moff_man]

if you have an air lock, running the thurmo fan constantly will not solve the issue it will heat up the area around the air lock and blow a head or crack it or such

radiator isnt that old how is the best way to get rid of an air lock i was thinking of taking tha radiator cap of and running the heater witht he bleeder cracked and seeing what will happen

Here is my way of getting the air out of the system:
With everything closed I fill the radiator through the cap.
Also make sure the overflow if full to the top and lid is fitted.
Blow through the overflow drain to pressurise the overflow and get air out of the overflow to radiator hose.
The close the cap and run engine for 5 to 10 minutes watching the temp gauge. Sometimes I go for a short drive.
Then with the engine still running, undo the bleed screw until a steady stream of coolant comes out.
Then check overflow and top up.
