Hey all, Today I wired up some twin thermo's from a EL to my VR 5 Litre, now iv put Twin thermo's on and have them running constant (putting a Davies, Craig switch in tomorrow) but iv made it so iv got a over ride switch to turn them off. Anyway having them running constantly the gauge barely moved of the resting point thing on the cluster.......... So I though id check the radiator hose to see how hot it was and if there was pressure there, I could squeeze the hose and hold it with ease even after the car had been running for a good 25-30 mins. as soon as I turned the fans off the temp started to rise like normal (so I knew the cluster worked), pressure built up like normal so I turned the fans back on and not long after tuning them on the temp started to go back down and lost the pressure in the top radiator hose........... Its a VR Worked and Charged 5 litre...... What im wanting to know is would it be ok for the engine to be running that cool if I was to leave the fans running constantly? Is it bad to have no pressure and heat from the water hose?

you need to check temp and pressure after driving not just running with no load engines need sufficient heat to run properly, too cool can be as bad as too hot my advice is don't leave them running constantly
