Title: changed by-pass valve no big result
Post by: m4nesh on 27 November 2003, 19:16: hello all

went to VAG and brought a by-pass valve kit. Installed it, correctly, and toped up coolant and ran engine on idle till fan kicked in twice and then went for a nice long rip and got home & topped up coolant again. Job Done

Only a moderate change in heat temperature coming out :'(...any suggestions because i've flushed system, forward and reverse flushed the matrix, changed the by-pass valve and now im sick and tired of the bloody car...

Any suggestions....my thinking is matix or heated gloves ;)

golfvr6 - what do u think about this idea?

When you push the heater setting to hot on the dash, it pulls a wire that in turn changes the blower unit to make the heat come out hot. This heater adjustment setting device, do you think that it needs to be corrected?

Any other suggestions would be greatly appreciated!!

Cheers

Post by: VW2010 on 28 November 2003, 13:23: I have exactly the same problem (I've posted this under "incorrectly fitted by-pass valve).

I've noticed that the hose going into the metal valve gets hot but the hose going from that valve into the baulkhead (matrix) is not really getting hot, do you think I may have a faulty new by-pass valve?

Post by: m4nesh on 28 November 2003, 14:09: I have just been into the forum named garage and somebody was talking about the heat gauge. My heat gauge sits at about 1/3 of the way doesn't get to half way, when i does then the fan kicks in, oil temp is at a constant 90 to 100 all of the time

Is that normal for the gauge to be at 1/3?

From this can you tell if my thermostat has gone?

Post by: golfvr6 on 28 November 2003, 14:25: How long does it take to get up to operating temp? should be about 5-10 mins if that.

Post by: m4nesh on 28 November 2003, 15:01: about 10-15 mins usually...... ??? Should I change the thermostat then?

Post by: Blue MK2 on 28 November 2003, 21:22: Im thinking of buying a by-pass valve kit. Is it an important mod. Im a bit wary as ive noticed alot of members have had problems ???

you said it ;)

Post by: richandhazel on 29 November 2003, 11:06: I also believe its a good idea that if it isn't broken, leave well alone, mainly as I never have the time to tinker. Having said that, this one is a safety issue, that VW felt strong enough about to recall the cars and have the mod done. You shouldn't have to buy the mod kit if it hasn't already been fitted, VW should still do it for free.............see previous posts.

Post by: shunta on 30 November 2003, 11:33: Have a look at the hose after the plastic outlet valve where it bends down. If this is too badly kinked you will not have alot of heat. I was having the same problem but changing the inlet valve sorted it for me. Nice and toasty in there now!
