| Post subject: | inline thermostat update |
I am 2 weeks into using the inline thermostat. I just wanted to post this for those who were thinking of doing this conversion. My stock tstat went south. It wouldn't warm up at all during idle and only to 1/4 guage during operation. I did the inline with a 195 degree tstat. I had pulled the relay on my viscous heater because it was running all the time. This saved me a couple mpg's anyway. The only drawback so far is that the jeep will not heat up past a couple knotches at idle. However 5 miles down the road the temp guage is at straight up 12:00 and holding. I haven't reinstalled the relay for the viscous yet. I believe that if the viscious is used that it will heat up better at idle. I have approximately 300 miles on the install so far. I just wanted to pass my findings along to my CRD brethren. I'll post if any adverse effects pop up but so far, so good. |

Did you drill a small hole in the t-stat you installed for circulation? If so what size? |

Picture the "smilies"  that are offered when making a post here. The hole that I drilled was probably half or less of that size. (sorry for that analogy but its all I got). I'm not sure at this point if it was necessary. The size hole that I drilled would flow very little fluid.

Thanks for your update. It looks like it is working well. Is there anything you would do differently if you were doing it again? |

I am no expert by any means on the CRD (but I am your average gear head) but I don't see anything that I would go back and change (so far). If you are looking to keep the under hood appearance clean and all stock looking, then this isn't for you. It is noticable as soon as you open the hood but as far as performance goes, it seems to be working exactly as it should. One note: Make sure you butt the new housing up to the old one metal to metal. If not then it puts it at a funky angle and it puts a crimp in the hose. Also you will need to clock the section of hose that is connected to the radiator slightly clockwise (as you are standing in front looking at the engine). This gives you a better angle to line the hose's "curve" up with the new housing outlet. You will see what I mean when you get into it. Also be mindful that when you disconnect the hose from the old housing be prepared for antifreeze to pour out. It is mostly coming from what is in the plastic overflow tank. I had to replace 1/2 to 3/4 gallon when I was finished. Go ahead and take the hose loose from the innercooler and move it to the side. It will be in your way the whole time if you don't. I found out that mine was real dirty when I did this. I can only imagine what the inside of that cooler looks like...lol Hope this helps. Steve |

I'm really glad to see that you've tried this mod. I was intending to do the same but my new t-stat was installed by the dealer on Thursday and the gauge points straight up now. I would like to check it's actual operating temp but my wife broke my IR thermometer while playing with the cat(gets him to chase the laser spot around). I wonder if the opening temp has been changed on the new units because it never used to point straight up, even when new. |

Here is the stat housing:http://www.autopartsdealer.com/meziere_inline_thermostat_assemblies-p355150-p.html I actually didn't buy from there but it is a little cheaper through those guys. I bought mine through Summit Racing just because I saw it there first. Here is their link: http://www.summitracing.com/parts/MEZ-WN0072/ From what I can tell it is a one size fits all. Good for us that the housing inlet and outlet is the same as our stock upper rad hose. I have a couple pics of it installed if someone can tell me how to post them. |

upload the pics to imageshack or cardomain or whatever, then post the url of each pic here with [img] tags. Which you can find on top of the box when you post a reply. The downside of an inline t-stat is that it does nothing for the bypass system we have... |

The guy that did this on the GDE forum, ended up using a tstat without the drilled hole, they actually have enough leakage to allow enough of a slight flow, for the tstat to accurately sense the temp of the coolant. Otherwise every one would have to drill a hole in the tstat for any application that uses an inline tstat. |

Just as a note to this thread, there are 2 different inline models the 71 and the 72 for different sizes of hose. I guess the CRD has a 1.5" diameter hose since the 72 is what the link is for. Just make sure you get the right one. http://www.summitracing.com/parts/MEZ-WN0072/ |

It is the 1.5" inlet/outlet. |

Another weeks worth of everyday use and no problems. I think this is a great alternative to the stock unit. |

I am still trying to get my arms around why a hole needs to be drilled. If the stock thermostat is either stuck "open" or we "gut" it, doesn't the coolant circulate around the engine (and heater core) anyway? I am thinking about the period of time when a properly operating thermostat is actually closed, causing the coolant to "bypass" the radiator and just circulate the engine until proper operating temperature is reached.. There is no problem with any of that. Wouldn't the inline thermostat, in its "closed" position, cause the same condition to exist? Thanks. |

The theory is that when the thermostat is in the normal spot then it is basically bolted to the block so that the water on the spring side will warm with the block and when the engine block water reaches the right temperature the thermostat will open. When you put the inline one in then it is no longer in direct contact with the block and since water is not a good conductor of heat the warm water might not ever reach the thermostat and thus the spring will never open....engine overheat, etc, etc. Due to this the small hole will allow at least a little movement of water and thus when the water gets warm it will open. That is the theory at least....
