Hello all,
I've never installed one of these, so I have a dumb noobie question... (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif) When a remote oil thermostat is closed, oil that is currently being pumped into it...does it return back to the engine or is it just stopped at the thermostat until it reaches it's opening temp? In other words, when cold, does oil go thru the thermostat and back to the engine - make a loop...? Thanks for any info! |

yes. it always makes a loop. it's either a short loop that bypasses the cooler or a long loop that includes it. |

Generally the cooler is in a loop, and the thermostat bypasses the cooler when cold. (many oil thermostats are two way valves, one inlet, and two outlets, selection on which outlet (or varied amount of each outlet) is dependant on the temperature)
Do not let a cooler get cold oil, cause it could rupture as cold oil can reach very high pressures if taken right off the pump. If you fit the oil cooler in place of the stock cooler (ie use the stock cooler inlet and outlet ports on the engine) the engine already has a pressure relief system to bypass the cooler when things are cold. This regulates the pressure so the cooler won't leak under high start up pressures. On an external cooler, you will likely have more cooling capacity, so a thermostat is required to prevent over cooling the oil, hence you run at an optimal oil temp. The external thermostat is required on aftermarket systems that bypass the stock pressure relief system, and is nice to have even on external coolers that are using the stock pressure relief system, as they go futher, and better control oil temp. |
