Essential for prolonging the life of all T2 engines,. Ensures that hot air cannot rise from the exhaust and cause the engine to run hot. Fits all VW T2 Bays from 1972 to 1979. Can also be used as an alternative for aircooled T25s.

When fitting, ensure that the smooth side of the seal is downmost; that the joint is not near the cooling fan.
The engine compartment in an air-cooled VW is designed as a closed system which keeps air flowing over those parts of the engine which get hot. As these engines run quite close to their temperature limit anyway, there is very little room for manoeuvre.
This seal not only keeps out road dirt from the engine, but prevents hot exhaust air being sucked into the engine compartment which reduces the air-cooling effect. When this happens, the unit runs hotter, increasing wear and reducing engine life. Don’t skimp on this important item – regularly check the condition of your seal, as they break up as they become old and allow hot air to rise.

  • Nice Product

    Great product for the price, fitted easily and length spot on, didn't read other reviews until i had brought it but had no trouble myself.

  • Perfect Fit

    The biggie is " Dark Side Down" when installing or the foam wrinkles on the softer sponge side. So I installed Dark Side Down and it gave a smooth, neat finish The length was perfect - I didn't pull it tight as I knew it would shrink and the ends matched to the millimetre. A necessary part of the engine installation as it maintains a slight positive pressure in the engine bay while moving, aiding the airflow to the fan and the engine cooling. Without it and spark plug seals 125c in traffic on a 25c day-oil temp in traffic and road to 90KMH, with both installed, it lowered oil temp to 110C at 90 and 25c. a good improvement.

  • Perfect Fit

    For those who have had failures above- The biggie is Dark Side Down , the softer foam side wrinkles when installed. Yes this IS the correct shape when installed DARK SIDE DOWN and looks great. I did not pull on or install the foam tightly as I assume it would shrink, the ends matched perfectly to the millimetre when installed. With no alt seal, engine bay seal or spark plug seal , on 25-29c days I was getting 125c oil temp at 90kmh. With the 3 seals now in place, I have lowered the oil temp to 110 C a big improvement. This seal is necessary to aid the fan function as it increases air pressure in the top engine bay while on the move. Great product.

  • 10 minute job, fits perfectly

    Did this in ten minutes flat (and I'm no mechanic). I found removing the air filter housing and ensuring all cables etc. were out of the way helped. Removed old, tired, messy, torn seal and replaced with shiny, new seal by doing what the instructions in the description here says and kept the smooth (black / dark) side down. It is a bit fiddly getting behind the fan housing but if you squeeze one lip in first then go back over it with your fingers and squeeze the other side in all goes to plan.
    Your bus will thank you for it!

  • Easier To Fit Than Expected.

    I thought this might be a pain to fit due to the limited access in the engine bay. Luckily I was wrong and its not to difficult at all. As the other reviews say "dark side down". The fit is excellent and it makes the engine bay look a lot neater. My 1600 runs far better since replacing the old one as well.

  • Buon prodotto

    La ritengo un buon prodotto.
    Montata come consigliano qui con la faccia scura rivolta verso il basso.
    L'ho installata senza tirarla e devo dire che si è adattata bene.

  • Easy to fit

    This seal was of a good quality and was very easy to fit, I fitted it shiny side down and now it tidies the engine bay nicely. This also keeps the engine bay air clean so you don't get any exhaust smells coming back in. Good product.

  • engine lid seal

    Received an engine lid seal from gsf it was a total joke . Length did not fit in any way ,could not close lid . Got new one from jk and it was actually cheaper than gsf plus it fits like a glove.

  • Good product

    This is an excellent easy to fit product. It did not come with any detailed instructions but after reading some of the other reviews I was able to fit it in about 10 minutes... Dark side down as all the reviews said. It was able to stand up to a bit of gentle pushing and tugging without splitting or damaging. I would recommend it.

  • Engine seal

    I'm no mechanic, just a lover of VW's and my camper! So, I'm gonna take it to my mechanic, as it was his idea to order and buy a new one. Looks the part, will instruct him dark side down, as per previous reviews, no doubt he would know that anyway, but it sounds like I know what I'm talking about. Thanks for great delivery too.

  • does just what it says

    Very easy to fit. Dark side down, take your time.

  • Engine seal purchase-well chuffed

    A super quality product that was easy to feel. Really pleased, buying from JK. Seal arrived quickly. Helen, Essex.

  • Good product

    Fits securely. You can fit it with the engine in, I had to take off the oil bath air filter to get right around the back of the engine. I was even able to pull it out a few times to reposition it without it being damaged but I would imagine you have to be a bit careful not to snag it on any sharp objects since it is foam. Fitted it with the dark side down in a t2 late bay.
