ae86 + gze cooling?
|
Wed, 12 March 2003 08:06
|
 |
nearly finished gze into ae86 conversion, however due to the fact that im retainging my aircon i cannot mount my two davies craig thermo fans on the front of the radiator. my question is, will my stock radiator be able to cope? also, as i plan to front mount very soon to cope with the extra boost, will this make it even worse with less airflow over the radiator?
what do people with gze'd sprinters do?
thanks.

i have just put a GE in a AE-71 pannelvan and had heaps of room in front of the engine (they are practically the same front end as a sprinter) for a thermo fan (14in). that should work fine its got heaps of airflow.

My GZE'd sprinter has a bigger radiator (not sure how big but pretty big) and a 14inch thermo behind it. If you run the intercooler pipes (for a front mount) the right way, you should be able to squeeze the aircon in, but my engine bay is packed, even though i have no aircon, with a thick frount mount. If you put the intercooler as forward as possible it should fit behind it. but it will be tight!
As far as the radiator, you should upgrade to a bigger one because the GZE will overheat tremendously at long idles. It won't really effect airflow if the intercooler is in front of, just connect the thermos to your air-flow sensor!
good luck!

I've had a gze in mine for almost three years now running a standard radiator and single thermo (12in i think) and front mount. I have never had a problem with the car overheating. I live in sydney and am frequently in stop start traffic. I sat in bumper to bumper traffic yesterday arvo for over 40mins and it idled away fine the whole time.
Although if you are planning on doing trackwork or spending a long time on the dyno you may need to upgrade to a bigger radiator and/or fit and oil cooler.

DAMO: you got all that in the front? what sort of intercooler are you using? could you please if possible send me some pics? also, did the aircon compressor bolt straight onto the bracket already on the side of the engine that holds the alternator? it has bolt holes for it but i cant put my engine in till next week to see if it lines up.
JONOZE: do you have aircon? what front mount are you using and where did you get the pipework done? also where do you live and can i possibly come take a look at your set up if need be??
thanks for all the help guys.

i also haven't had "bad" cooling issues sure the car gets quite warm, but doesn't overheat, i have an evo 3 intercooler,oil cooler, air con condenser and standard radiator and run bigger pulley with single 14 inch thermo. have you considered putting one fan on the front to blow through while the other is on the back sucking? also it is of note that the factory plastic underbelly thing actually is designed to aid air flow through the front of the car.

I use a rad from (I think!) an AL25 tercel in my ae86 with a turbo'd 4ag, which is otherwise the same size as a stock AE86 core, except it's got 2 electric fans mounted on it. The only time I get any kind of temperature problems is when I try to do a burnout etc., but then that always creates problems with a powerful car...

depends if you drive in traffic alot. if you dont do to much heavy stop start traffic just use one thermo just means the aircon isnt very cold at idle. or change water pump and use fan. two thermos covering the radiator will cause lots of pressure once your driving air in over the speed of the fans. just depends on how hard you are going to drive. me i would bin the aircon evapretive and make way for better intercooler with greater cooling for it and the radiator.

No, my car was never fitted with a/c.
The front mount is a relatively small aftermarket job. I cant remember the exact dimensions but its close to 400x200x65.
Initially i had an exhaust place do my piping, but when i changed coolers i redid the piping myself. I will be redoing this again when i get a chance as currently its press bends and doesnt follow and ideal route. Im in Ryde.

well guys if mine doesnt overheat with radiator, aircon, oil cooler, fuel cooler and then intercooler
cant see how theres a problem with a 4a?
only difference is i got a radiator from a mazda rx3
and yes guys it all fits infront of a 1g-gte

ok thats pretty nuts.
does anyone have like an above bumper shot of a spritner running aircon, front mount and thermo fan? i just dunno how its gonna happen. i can see running just a front mount or just a fan but not both. and no im not ditching the a/c i love it, besides its not so much the depth problem, rather width? if you understand me.

Have you thought of putting in a davies craig water pump with controller?? You can control when it comes on to your liking so if the car is getting hot just switch it on etc or set it to come on at cooler temps. Just a idea.

yeah thats an idea, but then i gotta spend a couple hundred more bucks.. it just keeps adding up! and i already got the fans so... but if all else fails i may have to try that. but then i wouldnt know how to set the pump to kick in early.

You get a in cabin controller..cant remeber what it looks like but yeah its easy as to change it all.
It will be more like $600ish both the electric water pump and controller. But i think it would be worth it cause u can pull the blades out of the stock one which will increase power aswell as having better cooling.
Have a look at this.

I can't find any (decipherable) pics at the moment, but I've got a 75mm thick core, and plenty of room for the AC, I only took it out while I wait to save up enough money to get the hoses done  There's enough room for one of the thin fans between the intercooler and the condensor too. Otherwise I spoe running the engine fans with the AC on at slow speed should help.

I have a 600x350x65mm intercooler, and a fuel cooler in front of my standard twin core T18 radiator with a single 10" thermo. no dramas at all keeping cool, even on the dyno.

this is crazy how are you people doing this? is there someone in sydney with a front mount so i can come take a look?
or more importantly, i JUST dropped the gze in today (bolted in not wired up yet) and i dont know how the a/c compressor can be adapted to the gze bracket. if someone doesnt mind can i come take a look at a gze sprinter with aircon? this is most important cause i can run the car wiht the stock cooler for now but i cant just leave the compressor sitting next to the engine? or even better if someone drives to my car (in Denham court servo) ao i can compare them next to each other. anyone?

I used the gze air cond compressor and modified the bracket to be higher so the alternator can clear the sway bar.

by modified the bracket do you mean redrilled the hoels lower down in the bracket?
this is no good to me as i want to use my original compressor cause i only got the motor not the gze compressor.
anyone using standard sprinter compressor with gze?

What alternator are you running?? Do you have a pulley for a ribbed belt on your air cond compressor? The standard sprinter is v-belt and gze is ribbed.

yeah i just noticed this when i went to work today, im very upset. does this mean no aircon? i really really like the aircon. unless maybe i can get a gze compressor? but then i gotta get the theing retro fitted and re oiled and gassed for the new type of a/c gas. hmmph. why is there no easy solution?

Couldn't you just change one of the pulleys so they are all the same and then get the right belt for it??

ok heres the update.
after putting on the exhaust i can see there is no way to retain my aircon. i have removed the compressor but the condensor and all the rest remains in hope that i can source a GZE compressor and it is a good deal smaller, but i doubt it.
secondly, the way the guy i bought my motor off has set it up, the altenator sits real low, just above the swaybar and uses the bottom two bolt holes where the compressor usually sits.
so i think i can say goodbuy to aircon. its a sad day indeed.
next Q: what front mount should i use? i was thinking S4 RX7. how much would it cost for a shop to make some custom pipes up and a bracket to mount the i/c? should the pipes both go past the drivers side of the radiator or have one pipe go round each side?
thanks.

dont give up on your a/c ,ive had to use the a/c compressor from the 4agze to run my p/s on my AE86 (also gze p/s pump), to me it looks that all that has to be done is to get custom plumbing done to hook up the gze compressor to the original AE86 aircon system, due to the fact im lazy i haven't done this yet, but i have left the condensor, reciever etc in place for when i do, im running extractors on my car so this may give a little more space for the pipes to exit the compressor, im using the complete gze LHS acessory braket without modifications (my alt is very clse to the sway bar but never hits, my car has run with this setup for over 30000km. it should be easy enough sourcing a complete braket and compressor on this site due to the ammount of people that have done gze conversions (and the fact that only a few have replied to this post indicates that there must be many lying around collecting dust)

my alternator is very close to the sway bar too, how have you got the belt running around the tensioner pulley? mine is running over it so that the multi-V's are running across it which is wrong but was how the guy before me had it so... any ideas?

i had to use the gze a/c compressor to turn my p/s pump, thus the idler pulley is used the correct way (pushing onto the flat side of the belt) its probably not a good thing that your idler pulley pushes on to the ribbed side of the belt, either track down the LHS acces. braket with a/c compressor or try different braket for your alt. does the 4ac bracket fit? i guess if the car has run like this for quite a while then i spose this system works, just keep an eye on your belt for signs of wear (the ribs may wear off). just a thought could the idler pulley be replaced with a ribbed pulley from another car? anyone here with V6 commodore- do they have ribbed idler pulleys?

some good ideas, thanks.
switching the idle pulley seems like a good idea.
in regards to using the stock bracket, to be honest i never even thought of that after all the conversion stories ive read with people saying its a drama getting the altenator bolted up i just assumed you couldnt use it.
also i wouldnt mind the altenator being higher up, not for the fact thats its too close to the swaybar rather that im worried about it getting excess water in it.
