Loadall wont heat up.

[Sprayer 1]

Our 535 loadall engine doesn't want to get warm. Cab heater cool and temp gauge cold after half hour working around the yard. Couldn't find a thermostat where I thought there should be one but could be looking in the wrong place. Any ideas please?

thermostat should be in the plastic housing on the top. Where the top rad house comes out.

You must have a thermostat in it, for the reasons you mention but also in summer it will be more prone to overheating as some of the water flow will go round the bypass in the block rather than go through the radiator.

you will need the whole top thermostat connection, cause its cheaper and better than buying just the thermostat, then the 2 x orings and then the plastic clip that holds it in.

Thanks, so you are saying it is likely to be the thermostat? Would this part be available anywhere other than a JCB dealer?

you asked were it was so i told you! but yeah if the heater dont get hot then its either the tap or the thermostat missing.

Its a standard perkins part, so could be sourced from just about anyone IMO! it even has the perkins part number in the plastic!

of you got a JCB dealer local then it wont be any different to if i sent it you, PLUS perkins are a shower of at the moment (have been since oct!) they have been working on a 7 to 10 day lead time sometimes more to pack and ship orders even if they are in stock and you cant track the order either.

Please can I join in? Perkins 1104 in an mf. Won't heat up at tick over, 1/4 up the gauge when working. Heater useless. Replaced Stat and alloy housing 2 years ago - better, but only for a short while. Was heating up eventually, but a few weeks ago got worse. Replaced Stat again at weekend, no different, both old ones look fine.

When cold, viscous fan turning by hand, but not free. Even if the clutch is knackered, would the Stat not get it warmed up?

I've always found in my manitou the same engine wont warm through to operating temp unless worked reasonably hard in the winter months- too much coolant too big a fan and too efficient to make much heat.

I have a plywood board that slips in and covers 2/3 the radiator for the winter, and a wooden wedge to jam accel pedal to 1500rpm for 10mins warm up before use.

I was on weekend duty when it was cold and found out tm310 wouldn't warm up when loading silage. I'd get warm air but if left idling between loads the gauge would hit the floor again.

same issues with my 530-70 temp gauge hardly rises when working heater not even luke warm Perkins engine what is this tap you speak of @ACEngineering

This one is on straw bedder, so goes cold when loading. Something happened a few weeks ago when it deteriorated, not coincident with the colder weather. Previously I had to eventually turn the heater off as too warm. 1st world problem, but you get far colder in the cab than wandering around the yard.

Lack of demist is biggest pain.

The cab heater tap or valve, on your machine its a expensive cheap plastic piece of sh1t located behind the cab side panel under the boom just behind the cab heater box where the filter is. Its dead easy to get too. It might be stuck closed.
