Block Heater for 8V-92?
Folks, I recently purchased my coach and have been trying to get familiar with the different systems as well as do some suspension maintenance. I have been looking around on my Liberty conversion’s engine compartment looking for my Block heater connection since it is starting to get cold. It doesn’t appear to have one installed that I can find, so, if I need to purchase one for the older model 8V-92, does anyone have suggestions of what type to get? On the phone yesterday, I was told they have one that mounts in the block and one that goes into a heater hose connection.
Just for reply sake, if the block type is recommended, how much water/antifreeze will I need to prepare for when I remove the plate cover?
Thank you in advance for the advise.

Anyone with an 8V92 that can post a photo?
On my 87 the block heater as I recall was on the RH side when viewed from the door opening and it was a 120V line going to an outlet up behind the cap. Liberty had a switch in the circuit breaker panel labeled engine block heater. As I recall it was a threaded pipe fitting so if you do have to add one it seems to me removing a plug and inserting the heater would not involve much spillage if you got the opening covered with your thumb after removing the plug and before inserting the heater.
I doubt unless you head north you will have much need for a block heater. I recall mine would start without the heater as low as 32F. Below that I ran the heater.

Thanks Jon,
I will take another look this evening to see if I can locate it or the threaded hole for one. I will also look inside the power panel for the circuit breaker.

Hi Richard
Jon is correct. The block heater is on the right hand, front side of the engine as you look at it into the doors. It is just behind the turning pulley at the bottom of the engine. You remove a plug and the screw the coil in place. Once the coil is in place, then the electric plug attaches to two prongs on the coil. I lost about a gallon of antifreeze when putting mine in but I had a recovery pan in place below the engine and was able to reuse it. I can take a pic but will need to tutorial on how to post pics to do so. The cost for mine was $90 for the unit including shipping.

On my old 89 where you filled the oil on right small door on rear above big doors was a male plug in where you pluged into block heater.Had a little flap on it. Was stock from Prevost. Bob

Is this it or what is left of it? Do I have to remove the 4 bolts that hold the plate? It doesn’t look like it is screwed into the hole,
Thanks

Yes, Richard that looks like what is left of it but there should be some male pins, mine had two, sticking out from that red circular area. I don’t see any there. Mine had two pins and the electric cord simply had a female plug on the end that slid onto the two male pins. The other end of my cord is a standard 3 prong 120 volt electric plug. If you can read a name on the plate, you may be able to buy only the electric cord. I would call Prevost and give them the unit number of your coach, they should be able to tell you if it is stock Prevost and if so, whether a cord is available, assuming your unit is in good shape. To determine your unit number, count right to left on your VIN number. The 8th digit from the right should be a letter. Combine it with the last 4 digits and that makes your “unit” number for Prevost parts to pull up a build sheet. For example, my 8th digit is an M and the last 4 are 1839, thus my coachs unit number is M1839. Hope this helps

Don’t rule out truck parts junk yards as a possible source for 2 stroke engine parts. Just check for continuity to insure the heater is good.
When I had my 87 it was often quicker and easier to get parts that way. And a whole lot cheaper.

i also installed a espar heater onto my bus and i usually set the timer to come on 2 hours before i go on a trip. it helps in warming my whole heating system.

When I call to order the block heater, they are asking me whether I want the 1000 or 1500 watt?
Which one should I get?
Thank you
Richard

Having lived where it reached as low as minus 20Fat least once during every winter, you can expect a vote for the 1500 watt from me.
-
Get the 1500 watt. If it is cold, it may make the difference in starting. If not, it will just warm it up that much faster.

You should be able to purchase a new block heater for either the series 60 or 8v92 engines for around $40. The series 60 has used two types, with the latest change in 2007 and the 8v92 has used three types over the years .
The part numbers from Zero Start (Phillips Tempro) are still in production and are listed below:
early series 60: 8605556 (120v 1500w 1″NPT)
late model (after 2007): 3500077 (120v 1500w 1 1/16″ STOR)
8v92 Silver Series : 8601712 (120v 1500w 4 bolt plate)
8v92: 8601704 (120v 1500w 4 bolt plate)
8v92 Silver Series: 8602611 (120v 1500w 3/4″ NPT)
Make sure the heating element doesn’t contact the block on (re)assembly.
