I have been nursing a leak on the top driver side (at the hose) of the radiator for a while now. The water pump finally went and I have that rust colored stop leak crap in everything. I am replacing te entire system (bypassing heater core for now).

I have read the threads of many who have gone before me on this subject. Armed with that knowledge and a desire to keep my ride healthy without breaking the bank, this is where I am.

Controller ? I haven't purchased this yet. Is there a little less expensive option that works well?

Looking for some guidance from you Uber Gurus to make sure I am on the right track. I want to do this once and get it right. Someday, I want to slip an 8 in here, so I figured I would capitalize on this misfortune.

Thanks for taking the time!

 

Cricket... Cricket....

 

is your 2 door a manual? the radiator you have picked doesnt have a tranny 'warmer'. unless it is, or you are planning on using an aftermarket one, that radiator wont work.
i think that there are cheaper controllers out there. there are some people who have done an e-fan swap and they will chime in shortly.
BTW, the cricket thing...funny....i like that $h!t

 

Yup.... It's manual, all manual. (Though the new factory power everythhing body fram and dash harness is in the garage waiting for the time and money fairy to pay a visit to my house!!)

All of my purchased parts shipped today. Starting the disassembly tonight!

 

Update- already received the dual fans, water pump and reserve tank. Waiting on the Radiator. Started some disassembly. Bought new hoses and pieces to bypass heater core. Still haven't purchased the controller. Was hoping for some of the technical feedback I have seen on so many posts with a few pros/cons. The controller I posted says it doesn't come with a relay. However they have a $99 dollar one that does.

I am really out of my element/comfort zone when it comes to electrical so any advice is appreciated! (I already plan on having a mech help me with the actual install)

 

If you have a mechanic helping with the install you should be fine, assuming he actually knows what he's doing that is.

It doesn't actually say you need a relay, but even if you did, I'd be confused as to where to put it. You can't put it between the controller and fans due to the fact that it is probably either A. PWM controlled, and therefore a relay couldn't keep up, or B. Variable voltage, and therefore a relay would send the full 12v regardless of the signal. And putting it between the batt. and the controller wouldn't make any sense either.

So I'm willing to bet you don't need a relay at all, but keep in mind, while I am more experienced in electronics than a lot of people, I have no experience with this particular product.

 

I'll toss my hat in here. While I have a 1990 K5, I'd imagine the same would apply here.

Your fans will need a relay and an inline fuse between battery 12v and the relay/fan.

Either way, you are going to have to make sure your fan is also hooked up to your AC compressor so that it definitely kicks on despite the temp switch reading when the ac is on.


Here is what I used on my 90 K5 for an aux fan for the AC (since I converted it to R134a

One question about the heater core, is it leaking or you think its just gummed up from stop leak?

 

I believe it leaked into the passenger side floor board. I haven't had heat since 2009. But took it with me to Bahrain for a year. Wasn't real concerned about not having heat. While I was there I went through my second set of motor mounts while under power and the motor jumped. The fan hit the hood and destroyed the shroud. I replaced them with urethane and replaced the shroud. I think that was the beginning of the current issue.

 

The guy at advanced auto said the stop leak wouldn't affect any of the internals.... My overflow is brown. My radiator is brown inside, and that stuff has coated the drivers side top to bottom.

Oops on the double post.
