Fmic Piping Hitting Radiator Fan

[cogs]

Hey guys, had to remove some intercooler piping on my car the other day and I took it for a drive after and I noticed my water temp gauge was about 20degrees hotter than what it usually gets to (was going through drive-through). Had a look under the engine bay and sure enough the piping had moved forward and was stopping the radiator fan from spinning.

Loosened a hose clamp and pushed the piping back towards the firewall and retightened but last night it must've come loose somehow (could be the slippery paint finish on piping) and had stopped the fan again (thank god for the water temp gauge).

I've seen some set-ups that have a bracket welded onto the intercooler piping and it secures to the cam cover. Are there any other options? Who makes front facing plenums for Rb20dets and how much are they?

ALso my thermo fan doesnt work (looks like the wiring has been cut). Is this easy to hook back up or should I take it to an auto elec?

It never over heats but I figure having the thermo working would be even better?

Thanks.

is it a just jap cooler kit?i just installed one, i thought that would be a problem but after a good thrash the piping hasnt moved. best thing to do would be to make a bracket

as far as plenums plazmamann make a plenum kit that relocates the throttle bodyso it is facing the front of the car. its about 800 or something. imo if you are not chasing huge power it is a waste of money. just make a bracket

if you dont know what wires to connect to where go to a auto electrician and they will sort it out quickly

just a side question. afte installing your cooler are the cooler pipes in the engine hot?

Hey Oliver, thanks for your reply.

It's just custom piping (the FMIC was already on there when i bought the car). It never came loose before but I had to take off some piping to get to something on my engine and now the piping is moving and hitting the fan.

"just a side question. afte installing your cooler are the cooler pipes in the engine hot?" If you mean the intercooler piping that is under the engine bay, close to the engine, then yes mine gets a bit hot too.

[OLik]

even the pipe for the intake?

best solution i think would be to concoct a bracket dude. why is it touching now and not before? have you forgotten to tighten a clamp? put a screw back?

or do as is instructed in the hybrid intercooler instructions. trim the back corners off the fan blades. you just have to make sure you use a template so that you take the same amount off each blade.

soemone told me to do the same thing, but to me that looks dodgy as hell! make a bracket and push the cooler piping away from the fans as much as possible

We cut the fan blades back on my r33 using a little alloy template we made. Not dodgy if you do it right. What is dodgy is when the fan continues to hit the piping regularly and fractures the fan blades! Thats what happened to mine, had to buy a complete fan unit to replace it, not cheap!

Does the thermo have anything to do with the air con? Normally on cars thay have a fan that runs for the a/c as well as an engine cool fan?

[cogs]

Maybe thermo is for air-con then and has been disconnected since air-con was removed by a previous owner?

Fan blades have already been cut btw.

Get a new piping kit from justjap....even those have the bracket to secure the piping to the cam cover...THEN if you still need to trim your blades then do it

[mad082]

my hybrid kit has a bracket to the cam cover and i had to trim the blades. i'd rather trim the blades and know that there is no chance of it hitting than not trim the blades and have a small chance of it hitting.

Hey,

I dont know if it has been mentioned but when i had this problem i used a bit of rough sand paper that i had stuck on the pipe where it was hitting the fan blades. This sanded away the fan blades after a few days.

Also it pays to make sure that all the hoses are tight and that the pipes are deep inside the joiners so there is little to no play in the pipes.

just let it hit the fan!

it will trim itself!

ahha!

[OLik]

man i thought i was dodgy, i have a just jap kit and the piping comes no where near the fans, there is at least 1.5" on space

Hey guys im in the same situation. If you cut the blades down on the fan is it still roadworthy? Also if you cut a hole for the cooler piping underneath battery is that roadworthy this is for a 34?

Thanks guys!
