Is Propane/Butane a “Wet” Heat

An often touted statement on the internet is that burning Propane or Butane creates a “Wet Heat” – potentially leading to damp in your van….

While there is a lot of truth to this statement, I’ve also seen people advising use of electric heating instead of gas to combat the problem, and here things get a little more complicated (I’ll get to that shortly!)

Motorhome fridge troubleshooting – fridge not working on gas

A common issue with the absorption refrigerators fitted to most motorhomes is insufficient cooling performance when operating on gas. Absorption fridges are interesting devices that cool using no moving parts, and require only heat to drive the cooling process (which seems counter intuitive, but if you want to read more about the working principles Wikipedia has a good article here)

Hymer Headlight Leveler Repair

A common issue on Hymer B-class motorhomes seems to be the headlight height adjustment failing.

The system is hydraulic and consists of a main unit on the back of height adjuster knob in the dash connected to hydraulic actuators on the headlights themselves via tubing. Over time the oil can leak out of the system leaving the headlights in their lowest position.

Fortunately replacement parts are available. Unfortunately it is a sealed system that needs to be replaced as a whole, and is likely to cost over £100 for the parts! Occasionally you might get lucky and find cheaper parts overseas.  I managed to get parts shipped from Germany which saved a decent amount versus buying them in the UK.

This is the system as supplied (as modeled by Muffin) with the dash mounted unit on the top right. You can see one of the headlight actuators at the end of the blue hose on the bottom left (the other headlight unit is hidden behind Muffin’s sleeve!)

First step in replacing this lot is to get the old unit out of the van! If you pull the adjuster knob off on the dashboard you can get to the two fixing screws that hold the adjuster.

The hoses on the adjuster go up underneath the dashboard to the bulkhead where they pass through a grommet into the engine bay. 

Here you can see the grommet and hoses on the bulkhead:-

Next step is to remove the actuators from the back of the headlight units – these just twist to unclip.

You can just about see one of the actuators to the right of the headlight unit here (looking down from the top):-

Once you’ve removed both actuators from the headlights you need to poke the grommet through the bulkhead (from the engine side) and feed the hoses complete with actuators through the hole in the bulkhead to underneath the dashboard. The whole lot can then be pulled out from under the dash.

Fitting the new system is effectively the reverse of removal:

  1. Feed the actuators though to the engine compartment from the dashboard side and seat the grommet in the bulkhead.
  2. Route the hoses to the headlights and clip on the actuators.
  3. Attach the switch unit to the back of the adjuster knob. 

 

In reality it’s a bit more difficult than that makes it sound as access/visibility under the dash is limited, and access to the headlights requires a bit of a contortionist act.  It’s all do-able with a bit of grunting and swearing.

Here’s Muffin in position feeding the actuators through the hole in the bulkhead:-
