Water Works On 205gti-6

Recommended Posts

All Praise The GTI

as above ive got my 6 running now, goes very well. only done 30 miles in it tho!

problem is the oil and temp seems to get hot fairly quick after a lil blast down the road and back. its running no oil cooler of any sort and i put the heat down to that id filled it up with just water no coolant just to get it running. yesterday i wired in the fan as standard just so it works for the mot on tuesday before i hard wire it on a switch. when the fan kicked in it purged water from the water bottle??? :excl:

im not sure if its to do with how i hooked up the hoses. i have teed the bottom of expansion tank to the bottom heater matrix hose and to the water pipe that goes down to the water pump and the thermostat hose to the top heater matrix pipe. im stil not happy with how my hoses slant up towards the heater pipes from the water bottle.

i need this sorted asap as mot tuesday and driving it 200 miles to llandow on friday!

PLESE HELP

my water temp goes up about 2 mile down the road and blows hot air...this is normal

 

my oil temp takes ages. You wont need an oil cooler as i cant get my oil over 95 even while booting it

strange how my oil gauge goes up at least 3/4 bars then? not sure if my sensors etc are on right plugs as i didnt convert the loom

dont see why the oil would get hot as engine standard except for a cam regrind and as you said oil takes awhile to get hot. its got 10 40 mobil 0ne s in it i think

i drive my car under 3k rpm till the oil gets hot...it takes about 20mins to get to 90deg running temp, then if i boot it goes up to 95deg

Hi,

 

Thats not how I have done mine but should work fine I think.

 

It Shows:

 

1. normal 205 hose from expansion tank to top of rad.

2. 2nd outlet on the top of the exp tank blocked off

3. Outlet on bottom of expansion tank that would go to the lower distribution block relocated and tee'd into heater pipe that goes near stat housing.

4. Original 205 heater hose

 

a bit vague on the last 2 but:

 

5. Bx (?) bottom hose with extra outlet for oil cooler

6. Cut down 306 top hose.

 

I took a slightly different route as I use a modified water distro block and a 205 pas top hose to handle the oil cooler.

 

Make sure you have bled the system properly, that it has good coolant and is holding pressure.

 

Good luck.

correct me if i'm wrong with this

my thoughts on this

 

1= expansion tank to top of radiator

2=bottom of expansion tank to heater matrix

3=what is this tee'd off for?

4=bottom heater hose into block?

5=water pump

6=thermostat housing

7=hose from pump to hose that runs on inner wing?

8=heat exchanger pipe from top of rad into thermostat housing

9=what is this tee junction for?

X=blocked off pipe on expansion tank

 

 

sorry if i'm thick :excl:

me and alistiarh and a few others run as above,

 

i've done 5+ tracks days like that and my temp gauge and water system has been 100% perfect

 

up to you which way you do it :blush:

 

but i know which way i use and it works (not saying other ways dont )

Probably because you're using an XU10 oil temp sender. Swap to an older sender and see what happens!

they do seem to heat up fairly quick

 

on a run or normal driving my oil temp gauge gets to 2nd line, on track flat out for 30 mins the oil temp ranges from vertical to 3/4

 

water on normal runs or quick blasts is the same which is the 4th line, on track for 30 mins it just goes vertical and thats it

 

i'd say thats workign pertty well :blush:

The bottom hose that t's off to the oil cooler/filter assy, i have used one from a 405 TD was the perfect size, correct angle and just needs a small bit cutting off the smaller hose to make it fit perfectly.

i was going to type that, but i didn't think my flame suit was up to the job..lol

 

seperate oil is always the way forward, as you aren't heating the water with the hot oil :blush:

 

ok, i may have gone OTT on my cooler (16 row 235mm) but i wanted the best avail. it has a stat too, which i recommend :(

right think i sorted the water heating up. must have been an airlock or something. after a quick drive with a little thrashing it sits at 4th line which all my 205s haveusually sat at, went up abit when booting it but soon came back down again. only thing that worries me is the oil warms up quick and and was a few lines across after the little drive(ok i did take it up to 120/on a private road of course)

i do plan on getting a nice new oil cooler 16 row like spiky got with a stat in when i can afford it! just hope its ok on track

the temp shouldn't raise on the road with a quick blast.

 

the water system on mine on raises when it's either sat in traffic or flat out on track, and then it only goes vertical

 

did you bleed the system when you put the water in??

 

both the bleed nipples???

 

for the od track day, a 13 row will be fine and is a bit cheaper, as mine is a full on track car i bought th bigger one

 

the oil should defo not warm up quick at all

 

have you plumbed in the original gti6 water/oil cooler? or do you have no cooler at all?

 

where does the oil gauge sit?

i made my own silicone hose kit for it using bbm hoses so only have the one bleed nipple on the stat housing.

took the water oil heat exchanger off as i think they s*ite! my mi gets hot as soon as you stationary with one on.

it is a purpose built track car so i want a big cooler! it is road legal tho hence why id prefere a stat in it too. ive got a cooler in the garage but would need get some hoses made up and get a stat so may aswell buy a new kit.

oil gauge sat at about 3 or 4 bars i think after a blast down the road,just a coulple of miles really but did wind it up to 1 cough 20. its got mobil one s in it i think

ok as a track car, 16 row it i then,

 

on a run mine sits at number 2 bar on oil gauge and 4 on water

 

3-4 after a blast is probably right for no oil cooling then,

 

i wouldn't do a track day with out a cooler minds

 

as for oil mobile probably be ok, but i'd highly recomment silkolene pro s
