After looking at that thread again, I think I need to take my car into auto tech and do some cleaning.

Does anyone make or sell an aftermarket revision made of aluminum to replace the factory black plastic coolant tube that is on the driver's side of the block?

Wow, I should have read this thread sooner. I just got my cabrio back from the shop where I had them refresh the cooling system... they replaced almost all of the pieces you guys have removed for this mod. Oh well.

Well, I'm in the process of removing intake manifold and I decided to remove those hoses.

Can some on write excact instructions what hoses should be removed (write numbers of hoses indicated in realoem to be removed) and how the circulation is redirected or capped.

Help is truly appreciated.

Anyone do this mod and still pass smog testing? I'm not sure what it's called in other states, but in california it is SMOG.

Just worried because I was thinking of doing this, but my tag renewal is this month, and I have to take it for smog testing again.

I passed in Texas. The heated throttle body is mainly for warmup and very low ambient temperatures. Some M42 export models didn't have the system at all. Tropical models deleted it altogether. A shorter stud for the throttle body is listed in realoem.com.

I just went the cheap route since my hoses were still good - I deleted the coolant hoses from the mix and removed the aluminum "U" tube. The heater plate is still there, it just doesn't have coolant flowing thru it.

As for the parts to delete, someone posted them in this thread previously.

Ok, now I got it. Actually this thread gives better picture of the "short cut" of the hoses. http://www.m42club.com/forums/showthread.php?t=2742

Well, here is the picture of re-route. Black water hose connects now the plug in block and lower water hose.

Also I started to change the blower motor but the motor was wrong one...

Next thing is to change fuel filter and control arm on drivers side (other side is already done)

Bumping an old thread... but just wanted to show my appreciation for the guys who posted this. Performed this hose cleanup today and am very happy with the results. Far less failure points than having all those hoses coming off the 4 way jobs.

Any other suggestions for plugging the coolant line on the block and the coolant pipe? I just used the "help" section coolant system bypass plugs, but don't know how long they are good for. Anyone run them for any length of time yet?

Just wanted to bump and see, after a few months, if anybody has any stories from plugging/rerouting the hose.

Everybody who plugged it still doing good?

Frankie · « **Reply #41 on:** July 26, 2008, 02:12:01 AM »

Still good. I have driven about 5000km and 5 track days during this summer.

I just ran it at our local 1/4 mile raceway yesterday in 85 degree F weather. Was expecting some cooling issues, but didn't have any. Ran it 4 times with a few being back to back with no engine shut off. No problems at all.

So everyone is using the "help" caps then? Or has someone found something more substantial?

Isamemon · « **Reply #44 on:** February 01, 2009, 10:50:54 AM »

just finishing up mine today, the help caps is the way I went
however the smaller cap is as thick as a condom, but it fits right inside a 5/8 cap which I needed for the black pipe cap. so I put the 1/2 in the 5/8 for the head port. might be overkill, but I could not trust the 1/2 inch cap alone
