I have a hydramaster spitfire and i seem to have a blockage on the heating radiator. Not being techical i don't know the names for the parts but here i go:-
At first i thought maybe the filters were blocked up, i've cleaned all 3 filters. Also my flow control was not working. Having disconected the two pipes from the raditor i conected the two pipes together using a joiner and i have full preasure filling up the header tank and my flow control works. so the problem is the raditor.
Can i work the machine even tho the radiator is not connected? How do i unblock the radiator? Any help would be great.
Thanks Luc

the Spitfire is a air-cooled machine so you can't be talking about an engine radiator. so do you mean the water pre-heater which uses heat from the blower to pre-heat the water?
if so I bypassed the preheater on my Blazer without any problem so I can't see why you can't do the same on a spitfire.

How old is the truckmount?
Ours had exactly the same problem after about 2 years of use. I put caustic soda in the radiator (taken off the machine obvouslly which was then rinsed out with water) which seemed a cure it for a while.
In the end we sent it to HM who fixed it so it would never clog up again.

It is a radiator mounted right behind the engine, it captures extra heat off the engine itself. Not the blower.

Hi
Its just like a car radiator in reverse.
If you live in a hard water area the it is proberly scaled up, you can get descaler but you need to use that before things have gone as far as this.
I would ring hydramaster & see what they suggest.
If you have bypassed it it will just mean the water will be cooler.

Had exactly the same problem about 3 weeks ago machine will work fine connecting the hoses without the rad which preheats water marginally found a bit of grit in rad blocking ous also check all filters to ensure no other complications..simon

I had this problem with my Spitfire 3.2 many years ago. The radiator captures heat via the exhaust to pre-heat the water before it gets to the header tank. In disconnecting and rejoining the hoses direct the water temp will drop very slightly but nothing to drastic.
