Would anyone happen to know if there is a filter for the air entering the cabin? And if so, do you know where to find it? Thanks, Jeff, Costa Rica.

Hi the pollen filters appear in almost all Hyundai vehicles and if you open the passenger rubbish box on the dash and lower it so you can see behind you will see a unit that can be opened (refer to vehicle manual) then when opened the pollen filters can be pulled out and replaced.

Now dont buy any for a week or so as I have contacted a company in Korea who will give forum members 25% discount and also post to any country in the world. They will accept payment via pay pal off the ebay site.
As soon as they provide me with a link I will put details on this site and on other forums I moderate on.
I have tested the products and they are really good quality and the carbon filter they sell work out cheaper than Hyundai OEM in the UK we will save about 50% on the OEM UK price (Tucson twin filtered models)

Cheers for now

Hey Itza,

Thanks very much. I went looking for the filters today before finding your post. I found it on my own but certainly appreciate your help. The heating/cooling system in my Terracan does not force much air into the passenger compartment and I think I see why now. The heater is stuffed full of mud. I didn't know when I bought this car, that it had come from an area of the country where it spent most of its time on dirt roads. I tried for several hours today, to take the bottom half of the heater housing off, so that I might clean the heater core. But, it looks like it might be an impossible job with the heater still in the car. I found and removed several screws and some snap clamps, but could not remove a couple of the snap clamps from the front side of the heater casing, the side that faces forward against the firewall. It looks as though the bottom half of the plastic housing, where the filters are, should be able to drop down and away from the rest of the heater, if all the fasteners are removed, to allow access to the rest of the heater, while it is still in place. I was afraid that even if I could remove the snap fasteners, I might not be able to put them back in place. So, I vacuumed as well as I could and put it all back together, until I can find out if there is a reasonable way to get it cleaned.

The terracan polen filter is not easy to replace but can be done. First remove the glove box completely, that meas that only removing the hang stops is not enough. You should unscrew the lower fasteners and remove the whole thing. Then, you will find a horizontal metal bar that is part of the dashboard structure. This one should be removed too.

Then you will have access to a vertical door which is located between the blower motor housing and evaporator housing. This door is about one inch wide by about 7 inches tall. Depending on terracan model, this door may be composed of two parts or a single one. Removal of door is tricky, since it slides up and down (after detaching a holding wire). Once door is removed, you can pull out the polen filter, that is usually composed of two halves.

Then you can push in the new filter or clean your old filter by brushing it with soap and water (dishwasher detergent). If cleaning your old filter, then let it air dry for a while before reinstalling and putting everything back together.

Do not leave ac system without the filter. Running the ac without the filter will cause gunk and mud buildup in the evaporator unit cells, which in mid term, will cause corrosion and leaks that cannot be repaired and evaporator unit should be replaced (very expensive).

New polen filters are available at Grupo Q parts department in Barrio Mexico, San José, Costa Rica. They are not cheap but sometimes they are a must when the old filter cannot be washed anymore (open holes for example). Part number is 97030-H1726

Hope this helps

Hi,

Have been having pollen filter adventures of my own...finally discovered a couple of days ago that the Terri has been running since I bought it (three months in total) with no pollen filters in place at all - that would explain the smell and the lack of colling, even with a/c switched on at 17 degrees...

Whilst waiting for filters to arrive, have liberally sprayed a can of aerosol disinfectant into the air intakes at the base of the windscreen with fans on full for a good half hour...what a difference in terms of smell - now much, much clearer!

Am going to pop in a temporary charcoal filter cut to size in the meantime until I get hold of the proper ones, although I suspct that the damage has already been done to the evaporator cells...

T'bob.

Robert B -
Thanks again for your input. I actually went around to the parts place that you mentioned and enquired about a filter for the heating/cooling system. The parts rep told me that he could not find one on his computer. I went there to ask about several parts that I was interested in buying, but got the same story on all but one thing.
I wonder if you might know if it's possible to remove only the bottom shell of the heater? I went as far as removing all but the last couple of clips between the heater and the fire wall and abandoned my attempt at removing the bottom because I wasn't sure that removing these clips would allow me to take the bottom of the heater off and I was worried about trying to get the clips and screws back in place. I think if I can get the bottom off, I could wash the mud that is caked all over the cooling coils. If I know that I can get the bottom off and back on without removing the whole heater, I will try again to expose these parts and try to clean in there. Thanks for your help. Jeff M.

Of course you can wash the filter and remove most of the accumulated dust. It is unbelievable how much dust and debris get caught in this filter.

To wash filter, first vaccum it real good to remove all loose dust and debris. then, soak it in soapy water (dishwashing liquid detergent in warm water) for a few minutes. Rinse with running water flowing "backwards" and pat dry with cotton towel. Leave aside for at least an hour to air dry as much. There is no need for the filter to be fully dried to be reinstalled again.

Ive done it in my terracan. From my own experience, filter washing is ok for about two or three times. Then the filter becomes too damaged to even attempt another wash.

And the bottom half of the casing of the heater Robert? Would you happen to know if it's possible to remove it while leaving the top casing of the heater in the car? I would like to try to clean the inside of the heater while it is still in the car, so as not to have to unhook the air conditioning system or the hot water system or remove the entire heater from the car. Thanks again, you're very helpful.

If I remember well, the only way to remove the heater (or any of its parts), you have to first remove the a/c evaporator. That means major trouble, since the gas will be released and proffessional instalation should be done later.

thnking about this, I do not feel the heater needs cleaning if the pollen/dust filter has been used. Anyway, even if the pollen filter was removed, all the debris will be caught at the evaporator cells, right next to the pollen filter. Very little dust will get to the heater element cells.

If you feel you need to clean the air ducts, then its a lot easier than you think. For the center ducts, remove the center dashboard panel (just pry it out by pulling out the ashtray). The side vents are a bit harder but the vent louveres cay be pried out too. then, using a moisten rag and a flexible wire, you can wipe clean the ducts (I hope you get the idea). Then, you can spray some lysol into the ducts and put back everything.

Remember that the pollen filter is the major odor trap in the a/c system. By replacing the filter you will get rid of about 90% of odors.

Here's a couple of pages from the service manual, with blow up drawings of both the heater and a/c from the terracan. I am sure those will help a lot figuring out how or what to remove safely.

Thanks very much for the blow-ups, they help a lot. I can see in the first blow up, HA-32, that the Lower Heater case, item #4, looks like it should be removable by itself. The last time I tried to remove it, I got nervous about not being able to put the clips back in place if I removed them. I see that there are three clips on the back (firewall side), and if removed should let the heater case drop down. I had it all loose the last time, so those clips were the only things left holding the case in place. If I can figure out how to put them back in place, I will make another attempt.
I could see when looking in through the hole where the filters fit in, that the heater core or cooler core was severly caked in mud. The previous owner either drove the car on gravel roads for some time, without the filters in place or the filters were so dirty that the fan pulled dust past them into the heater/cooler core. At any rate, the mud is thick inside. If I could get the bottom case off, I could rig up a spray nozzle for my garden hose and spray a fine spray of water into the core and catch the muddy water with a basin on the car floor. I'm sure the system would work much better if cleaned.

Thanks again, I appreciate your help. Jeff M.

I still think that if you remove the lower part (4), you will get in trouble getting everything back together. Look at parts 9, 10 and 11 ("doors"). They seem to be held in place by the upper and lower shells. Also, the heater core seal (32) is attached to both upper and lower shells.

I do think you have to get all the dust crud removed, especially from the a/c evaporator. Remember that the a/c system has a drain to release all the condensed water. This drain pours out from the firewall (engine compartment). I guess that if you still do a fine water spray from the pollen filter door, without disassembling anything, you can still get it clean enough and the water should drain completely though the a/c drain.

I don't know even if the heater section can be worked on (removed or disassembled) without first removing the cooling section. My guess is that is not possible. I strongly suggest you get a proffessional opinion here.

Back when I had to replace the evaporator core (due to mud buildup and rust), the people a SAMUEL (across the street from Durman Esquivel at Calle Blancos), did a fine job and are very knowledgable. It doesn't cost a cent to drop by and ask, better if you take the car with you.

Hello Robert,

Can you tell me which barrio Samuel's is in? Which Calle Blanco? Near which Durman?
Thanks, Jeff.

[Robert B.]

Since I don't know how knowledgealbe you are around San Jose, I'll try to put this as easy as possible:

Samuel is located over the north side of San José, on the road that goes from Uruca to Calle Blancos (and eventually meets the loop near Hipermás in Guadalupe). That road crosses (overbrigde) the highway to Guápiles.

I understand you will be coming from some place around Sarchi, so that means, you can drive to San José, exit the highway near Hotel Irazu towards Uruca. At Uruca street, make a right and keep there to the Shell gas station, where you should take a left. From there, you keep east towards Cinco Esquinas. Still going east on the same street, you will pass over the bridge that overpasses the highway to Guapiles. A few meters after you will cross the train tracks near Macopa hardware. Samuel is located about two blocks east from the train tracks, on your right, across the street from Durman Esquivel (the pvc pipe factory). Their phone number is 2256-6080.
