Excellent writeup. I've only 2 comments: 1. on removal of the 3 tstat bolts to the block Squeeto recommends using a wobble extension. I second and third that motion as a regular 3/8ths extension binds on that "hump" in the manifold below the lower back bolt making removal difficult and reinstall without cross threading even more difficult. If you don't have a wobble extension buy one or you can try a 1/4" extension and socket which may clear. 2. when I did mine I found the temp sensor wiring clip was upsidedown (e.g. the sensor was screwed in so the release clip was on the bottom) so I had to pull the tstat before I could get to the release clip. I did take care not the repeat that problem on the reinstall. |

Great report! I will be doing my timing belt and thermostat replacement soon and noticed your modified thermostat with what appears to be a typical thermostat neck adapted to house a regular thermostat. Is that something you did yourself or is someone out there modifying them? |

Yeah, I found that topic after I made the last post. I will be looking forward to him getting back into production after he settles in and gets set up. I didn't study all of his pictures and processes, but I have all the equipment to do what he has done. I would rather pay him for doing all of the R&D and labor, and not have to re-invent the thing. Looks like he did some nice work. For now I will just buy the replacement Crown thermostat. That way I will have a core to send him. |

It's detailed posts like these which make this community so great. Without them, owning these little little beasties would be...well...I wouldn't own one...never would have bought one, in fact. Bravo! |

Just replaced the Thermostat(in wife's Jeep) because the fix with the Stant 13519 didn't work on this Jeep. It has been working just fine with my other Jeep (the one that I drive) for over a year even in the extreme weather that we are having in the Midwest, sub zero temps. I will be testing it tomorrow. I also put it some tee's for the future of using WVO and Bio-diesel during the winter. I use Bio-diesel during the summer. I have a good source for Bio-diesel so I would like to use it during the winter also. |

Thanks as well. My temp is right at the mid-way point now. Like all repair jobs, I was on track for a quick finish but dropped the gasket "somewhere" while sliding the replacement T-stat in place. Took over an hour to find! This is why I usually take it to a pro! |

Brilliant guide! Thanks very much. Replaced my thermostat today with a Crown replacement unit and my needle's now sitting exactly where it is in your guide!! Cheers, Mike. |

Great guide, thanks. FYI if you are in a pinch the drain cock can be opened with a 17 mm wrench. Just recommend you are gentle. |

I know this is an older thread but I use a search button was wondering if this inline thermostat that was posted in the German site worthwhile looking into or should I spend three times the price and get the housing? |

get the housing. There has been some discussion on inline tstats, and ppl wondering if it does more harm than good. |

Get the OEM thermostat; the jury is still out on the in-line thermostat, some are of the opinion that an in-line thermostat can cause a head gasket leak and / or a cracked head... Without definitive proof either way at this point, an in-line unit is just really not worth the possible risks and consequences IMHO!!! |

I have an electric fan kit to install. Should I do both at the same time? I also have a webasto heater to install. Should I postpone the thermostat and / or electric fan until I am ready to install the Webasto? |

At the very least, install the heater and coolant lines for the Webasto; you can wire up and do the fuel lines later, unless you are dropping the fuel tank at the same time to install a lift pump. Try to do as little overall labour as possible, Jeffrey.... You more than anyone I am aware of knows what a P.I.T.A. a Liberty CRD can be. Still love mine, though! Best regards, |

Should I postpone the thermostat and / or electric fan until I am ready to install the Webasto? I wired my fan into the existing A/C fan harness. I ended up buying a 2 speed fan like the stock unit and was able to control the high and low speeds straight from the ECU. We have the ability to adjust the fan activation based on coolant temps straight from the ECU and tuning. It allows you to bypass the whole 3rd party fan controller annoyance. I simply bought some GM weather proof harnesses from Carquest and cut the plug off the stock A/C fan and re-wired it onto the new fan. |
