Year 2000 Bongo heater

[Astroman]

I have the heater set to 32 (max) but it seems to be total pants. The only time it ever gets above lukewarm is when I'm stuck in traffic and the temp gauge goes up from its normal position of zero (another weird Bongo thing I think?).

Anyway, so is there something I can do to make the heater work better or is this just the way it is?

sounds like stats been removed

look under dash by steering

round disk with links from a servo

look for one disconected

[wonkanoby]

what lumps in it

is heating manual with sliders or electric one

sounds like a newer unit if set at 32.

is the coolant level up to the full mark when the engine is cold. does sound like the stat is out or stuck open.

or the heater rads full of crud

feel the 2 hoses go through bulhead once its hot

both should be hot

We had a similar problem and thoroughly bleeding it with the heater and fan set on full sorted it. Not sure if this is recommended but it worked for us.

Thanks all, plenty of things to try.

Hello fellow yorkie.
Im having sameish issues. Your sound like a lack of coolant flow or blocked matrix. They do take a long time before they heat up. Its a big engine and if short runs rarely get heat into engine block to work .
Wherabouts in york r u. Could have a look if you dont get sorted
Ady our cc goes up to 32 in our 95.

mike has yours got the digital system, on a 95??.

another thing to check astroman, at the passy side of the heater controls, towards the glovebox, is a 10mm (vent) looking thing, this has a cabin temp sensor fitted behind the grill, maybe a remove/blow out/hoover may help clear the accumulated fluff that is blocking the fan unit in there.

We have the same as the photo mike posted up,

Be a bit careful prodding around or hoovering round that vent. I've read of people breaking the thermistor by being heavy handed with it. A very fine artists brush and hoover pipe held some distance away should be sufficient to remove the dust.

Sounds like classic symptoms of a missing (but why?) or stuck open thermostat.

Where is the thermostat? I mean I know it says above it's under the dash near the steering, but what does it look like?
