So bought my tubby a couple of weeks ago and love it !!

 

However when using the heater fan i was momentarily blinded by a sea of sand, dead bugs and god knows what else. Also the heater was stuck in the luke warm position, after investigation it was clear that the heater needed to come out !!

 

So finding the seized heater flap once the heater box was out was easy, but how to fix the annoying trate of a free facial scrub every time the fan was turned on is going to be harder.

 

Having spent a career maintaining cars at dealership level  I have a few tricks up my sleeve.

 

So i have decided to modify the heater to accept a pollen filter.

 

 

 

Has this been done before ??

Search "sock mod"

you are pissing in the wind... unless you worked on Lada's

Heater out and measurements taking place

[Johnboyhgt]

So this is version one of what I am attempting to do still need to construct some type of door to seal off the heater box (good job i have a stainless table top in the garage spare) and need to construct a framework to prevent it from being dislodged at speed.

 

Pollen filter is a bit fat so need to get a slim one from some car or other but all in all pleased so far.

Yes, what you really need to do with this heater is fit more restrictive parts.

[Johnboyhgt]

This is the intake end not the blown end, surely it can get at enough air ?

[techieboy]

I struggle to see the point of trying to fit a pollen filter in a car that's open to the environment in as many places as the VX is when all you're trying to do is stop larger particles.

 

I had a circular pollen filter from one of the German speedster parts companies in my heater air pipe at one point, it just strangled the flow and made the anaemic heater worse than ever. Slightly better was the integral foam filter in the Revotec heater hose kit which seemed to mitigate some of the flow loss. Never bothered with the sock mod though guess that probably affects the flow even less. 

 

What I've settle for now is a fine aluminium mesh siliconed to the heater fan inlet itself, though that's on a wholly different Fezzasus heater.

The part that operates in the middle is fcuking shite! therefore it needs as free a flow on the input as possible.

 

Nb. Fezzasus really does know what he is talking about... If he comments I would listen.

 

 

[Johnboyhgt]

Right, to avoid further unnecessary work as a compromise I will test as is with gaffer tape etc and see what the flow is like. If ok i will complete the mod if not i might block off the front intake and take the air from the side (ie battery area) from the hole I made thus avoiding the flies and grit too.

At what speed? In stop start conditions there is no air speed so the fan must suck air in, you've made the job harder by fitting a pollen filter.

 

The bigger problem you'll encounter is the construction of the heater matrix. Riveted ABS. As the heater ages the plastic distorts and large gaps form. By making the inlet an area of higher restriction, you start pulling air more air through the gaps, potentially bypassing the heater matrix entirely.

 

I would suggest that you want to fit something more open than a pollen filter if you want to maintain heater efficiency.

or just man up and take the face full of dust

[Johnboyhgt]

Ok will get some tight gauze then for the inlet, its obviously a subject that has been thrashed out at length by the looks of the information received. Thank you all for your input.

I think the dust and dead flies build character

yes yes, but they arent part of servicing cars to a dealership level
