| Post subject: | Tools needed for Viscous Heater Bearing Replacement |
My Viscous Heater bearing is starting to squeal. Very obnoxious. So I want to do the replacement as discussed by Roostre (see See viewtopic.php?f=5&t=60567). I have never done any such bearing replacement, but I have checked out a number of YouTube videos. Lots of different possibilities with these types of bearings. So, for those of you that have done it, what tools will I need? I am only interested in replacing the bearing. I don't care if the heater heats or not. By the way, I found the bearing at AutoZone for $14, see part number MT2149. (But they won't do store pickup for it?) |

Ok so I have just done this- Put new bearing in freezer Drain some coolant off from rad lower drain. Unbolt (2bolts one large Allen key type one normal) and the two hoses You'll need to hold the clutch face and undo the 10mm bolt and remove face Remove circlip and apply pentrating spray Use hammer or a puller to remove pulley wheel Tap out old bearing wit something large try to keep it in one piece to use as a form to put in new bearing Heat pulley wheel Removed bearing from freezer Tap in to place Refit as reversal of removal |

The viscous heater heats the radiator fluid (coolant). It assists in warming up the engine faster since Diesels are notoriously slow to warm up. |

Hexus is correct but how much help is debatable. Down here my viscous heater has been disabled by pulling it's clutch relay years ago and I notice no difference. My son (stoutdog) is working in Kearney, NE where they have much more "real" winter and he reports a marginal improvement in the delivery of cabin heat and engine warm up with the viscous heater engaged without use of the block heater. In point of fact in the winter if you plug in the block heater on a timer for like 1 hr or so before startup you probably get more benefit than the viscous heater supplies. So is it a critical component - no other than the serpentine belt runs across the viscous heater pulley (translation if the bearing goes bad it's hard to reroute the belt so you kind of have to put in a new bearing) but lack of a functional viscous heater doesn't really matter from a vehicle operation perspective. Is it a convenience component - sort of but block heater is better. |

Thanks. I will give it a try. You don't have any pics of the a. waterfield wrote: Tap out old bearing wit something large try to keep it in one piece to use as a form to put in new bearing step, do you? I can't picture how this would work...maybe once I get it uncovered it will become clearer? |
