Radiator in Vantare
Has anyone ever changed the radiator on a Vantare generator. My generator shuts down I suspect because of over heating. I thought maybe the radiator was full of dirt but I discovered the fins are disinegrating. They look fine but fall aprt when you touch them. It doesn’t look like too tough of a job. Finding a new one would be the next thing.

We have a “98 H3-45 Vantare and have had the radiator out twice in order to access the house AC which is “hidden” between the genset which is on the passenger side of bus and the genset radiator which is next to the inverters on the drivers side of the bus.
Removal is simple ours is out in under 30 mins. I wonder why your radiator is deteriorating… ours is in excellent shape?
You say you suspect an overheating problem… we have temp and oil gauges for the genset in the electrical panel inside the bus to verify that.We have two slides and I do know that non slide coaches have a different configuration in the bay area so I’m not sure if this helps you or not but our radiator is a very easy removal project. A good radiator shop should be a big help to you once you have it out.
Patience in adding coolant after you reinstall it will be a plus too…it takes awhile.Good luck!!

Scott Check we a radiator shop, sometimes they can be rebuilt. Rick

Looks like we have the same coach. I figured fact that the radiator is ten years old could be the reason it’s turning to dust. I assume you drain the system thru the radiator. I have the same gauges but they’re not in a good spot to monitor while going down the road and after it shuts down it’s too late to check them. I’m just guessing on the overheating because it should only shut down because of low oil pressure or overheating. At any rate the radiator needs replacement I would think.

Yeah, I’m thinking they can use the tanks and solder in a new radiator section.

Yes hopefully the radiator shop can take care of you….I just recalled that while we had it out the first time we put in a new fan motor as the old one was squealing slightly… we have also has all 4 injectors rebuilt… Our genset has 9700 hrs on it… when I called Powertech for some info one time they were very helpful and great to deal with… they said they are built to run and they work better under a full load.
Our bus spent much of its life at the Nascar races with the generator running.
Glad our H’s are the same… maybe we can share info from time to time… we have had ours for 2 years now and have made numerous repairs needless to say. -
Mine only has about 2000 hrs. on it. I’ve fixed afew things too. It’s a little like keeping the space shuttle working I think. I know the previous owners and that really helps. They’re great people and know the coach as they owned for 5 years.

Got it out 451 dollars to build a new one. Are your hoses one long piece or smaller ones connected together? Mine are in two or three pcs. I’m wondering if I should replace them while I’m at it.

I will look tomorrow and let you know.

If you replace radiator hose be sure to use re-enforced on the suction side.

Sorry for the delay… was out of town… My hoses are all one piece re-inforced. Might be a good idea to change them out while it’s apart.. less joins = less leaks.
Good luck. -
Also forgot to mention while you have access to your main house a/c (if yours is like mine it is buried behind the radiator which has to be removed to access it) I would check your ductwork that goes up into the bus from that unit.. ours was just terribly deteriorated and a very easy fix… infact our replacement ducts are so superior to the original.. we were cooling the bay as well I think but not anymore. also a great idea to blow the dirt out of the entire bay making sure the a/c is good and clean.
Just a thought !! -
By reinforced you mean with a spring inside or just heavy duty hoses? Mine feel like they have springs in them.
-
I took a picture of the hose for you but couldn’t post it for some reason so I sent it to via your email… hope it helps. It feels like it has a steel wire or cable running spirally through a very heavy thick rubber hose.

Got the radiator back in and trying to fill it. It does go slow so far I still can’t keep it running. Still overheating but I don’t think the coolant is getting circulated because the radiator doesn’t even get warm. Maybe I still need more coolant. I’ll try again tomorrow. Gonig to Louiville Wed. for the Good Sam rally. Might be somebody there can look at it.

As the radiator is not warm tells you the thermostat has not opened.
You probably have a air lock.
Someplace is a bleed valve to clear the air in the system. The location will be in the owners manual.
