Thanks WW! Do you, or anybody else, have any experience with either of those particular in-line and screw-in versions? If not those, can you or anybody else recommend a particular one? Has anybody added a second battery to their CRD? If yes, how did you do it? I greatly appreciate the info received so far, as I'm trying to get this done well before winter starts here in NM! Steve |

Post subject: | Re: Grid Heater Project (Proof of Concept) |
Thanks again, WW! While the screw-in types are certainly cheaper, I'm concerned about securing them to the pipe (I have the Weeks intake with the Samco hose). I believe a nut would have to go on the inside of the pipe, right? That nut would have to locked on there somehow, but still be removeable. One way to get around that would be to machine a boss with the proper thread size/pitch and weld it to the pipe, but that's laborious too. That in mind, at this time, I'm leaning toward the in-line version. Yes, it is approx $400, but as they say "buy once and cry once". Would love to have a Webasto heater, but I'm seeing approx $1400 for one that'll fit the Sasquatch mount. If that's indeed accurate, then it's way more expensive than the in-line version. About that in-line one: they come in 3" and 3.5" o.d. versions. Do you or anybody else know the i.d. of the Samco post-intercooler hose? I've got mine sealed really well, so don't want to have to break it loose to measure it. Also, what make/model of battery is it that you've got installed on your sasquatch mount? THANKS for the info!

Hi Kids, I've been away from this forum for some time, life got in the way of my CRD project. I've gone down the grid heater rabbit hole and this is what I found. This heater is from a compact tractor. The footprint is the same as the FCV.The problem is that teeny tiny hose connection. The solution is to remove it. I don't have access to a milling machine, so the correct size hole saw will have to do. Now we need to port match and drill and tap the elbow for a boost gauge and thermocouple. Now we test it. I think it has potential. 300 deg F at 34 amps of current draw. This will replace the FCV in my CRD. EGR delete,OMG, call the EPA. |

If that is the same size and bolt hole distance as the flange on the intake manifold/valve cover, could it be sandwiched between the intake flange and the FCV delete elbow that many now have? A lot of owners no longer have the OEM FCV elbow. But it certainly looks like it has potential. Any ideas on cost for heater? |

Green Farm Parts shows them for $66.10. Some places show a newer version, different part #, $100ish. I started fooling with this in 2015. I wanted something that could replace the FCV and was plug & play. At the time I wasn't aware of any kits, plus I already had the heater for my tractor. |

The Weeks intake (at least the one I have) has an o.d. of approx 2.25". Of the screw-in heaters mentioned in this thread so far, which one's length would be the best fit for the Weeks intake? I tried looking on-line for the length specs of the mentioned heaters but couldn't find anything on that. The heater-matched-to-the-FCV is an interesting option though... Thanks all, Steve |

Thanks (again) WW! Greatly appreciate your replies and technical input. Believe it's time I get off the fence and move on with this project, so I'll keep all informed as it goes along. Steve |

Hi all, I'm making (some) progress on this topic, but have a question I want to make sure of. I got a solenoid (an Standard SS-547) for use as suggested, but there's a note in the box that states "...do not use this solenoid for vehicles fitted with an on-board computer...vehicles with a computer require a solenoid with suppression diodes...". Since this solenoid won't be tied into the start system, or really any other standard vehicle system, and only used in this auxiliary heater aspect, it still would be ok to use, right? Any inputs will be appreciated! Steve |

Any inputs will be appreciated! Steve Researching online, seems to be a Ford thing with the "S" terminal causing dangerous high voltage spikes when the load is removed and the magnetic field collapses that can backfeed into the electrical system and damage a processor. They recommend adding a diode in the circuit to the "S" terminal so current can only travel in one direction and not backfeed when the solenoid contacts open. I personally would not use a Ford type solenoid but instead I would use a heavy duty Cummins/Dodge Grid Heater Relay. They are rated for 100 Amps continuous duty and are installed OEM on many computer equipped vehicles and designed for this purpose. Plenty of them available online. Two different styles, either one of them would work. RELAY-75565 or 5187880AC |

Thanks WW! I'm more familiar with those single wire-to-the-switch kind of solenoids, as shown in your diagram above. What would the wiring diagram be for the Cummins kind of solenoid you've suggested? Steve |

I think I'm going to jump on this boat! Will be ordering the grid heater. I have the factory elbow. Thanks to all that have worked on this. |

STILL pushing this noodle up the hill, it seems... I have a Standard Motor Products (SMP) DIH4 screw-in heater, and need the thread size and pitch for it. I called SMP, and they said "...we have no specs on that item...". Does anybody know the thread size and pitch for it? Steve |

And it's WW for the win, again! Your ability to provide accurate info, and quickly, is quite noticeable and GREATLY appreciated. Steve |
