Thoughts from Mountune Radiator Install

Hey Guys,

Just installed my Mountune radiator yesterday and wanted to share a basic walk through and some notes on install, just in case anyone needs help when they do theirs later.

After doing a lot of reading and video watching on Youtube to prepare, I rounded up a couple friends and blocked about 5 hours to complete the job. We finished in less than 2 hours. It's really not that bad.

Stock radiator removal:

Jack the front end up and secure the car properly. Chock the rear wheels. Grab some cardboard to put down because without a release valve on the bottom of the radiator, it's going to be a mess when you open it up. There's really no way around that.

You don't need to pull the bumper to install the radiator, but I did remove the headlights for extra clearance. It helps give you more access to the area where you'll be working.

Remove all of the necessary clips on the top over the radiator. Pretty straightforward.

The fan comes out on top. There are a couple of clips that you'll need to unhook on top and then pull the fan up out of the bottom mounts. You should be careful, but basically you just pull it over to the driver's side and up, little by little until it's clear. I didn't make any contact with the stock radiator when removing the fan. Be patient and work it up and over until it's able to slide up and out. It's tight, but it wasn't that bad to do.

The radiator comes out on the bottom. Getting it to pop out of AC condenser channel was kind of tricky but with a little wiggling, it slid out. Be careful to not make contact with the condenser or the AC lines. Again, not that hard, but good lighting and hands on the top and bottom of the car make it easier.

Install of Mountune radiator:

The piece ships with a nice blue plastic cover on it. I HIGHLY recommend leaving it on while you're installing the radiator and the fan. Just make sure to cut opposite corners to allow for the pieces to slide out easily when the radiator is in place.

Getting the new unit in isn't too bad and keeping it covered with the plastic guard gives you a lot of confidence to get it to where it needs to be. You'll need to get the top of the radiator to slot into the AC condenser and then you'll be able to get the bottom radiator mounts into place. Once you do that, connect your hoses and the clips on top and you're good to go.

I was not able to use the stock pinch clamp for the upper hose. It wouldn't fit over the neck of the Mountune radiator, so I went to Autozone and got a few hose clamps. I prefer these anyways.

From there, you'll just need to button everything up and then fill and bleed the system.

I used a bottle of water wetter and then about a 40/60 mix of coolant/water. I filled the reservoir and then ran the car. Open the bleeder valve to let the air out and then crank the heat once you get up to temp to make sure you get all the air out of the lines. Once you're getting a consistent flow of coolant out of the bleeder valve, you're pretty good.

Drive the car around and then check the fluid level and top off the coolant. Repeat as necessary.

Verdict:

After doing multiple pulls and getting stuck in some stop-and-go traffic, I only saw temps come up to about 190 max. With the stock radiator, I was over 210 regularly. With normal driving, I was around 190. With the new radiator, I'm closer to 186. Granted that it's only been on the car for about 30 hours, I'm happy so far. I'll plan a trip up to the mountains to push it and see how it does, but I'm optimistic that this will solve my cooling problems.

Sorry that I don't have pics or vids, but the process really wasn't that bad. Just take your time and make sure to keep the AC condenser and new radiator protected.

Nice writeup, thanks for taking the time to share you tips/advice.

Ya only reason we pulled the whole bumper on mine when I did it was I was also doing my intercooler so why not. Good job man great radiator.,
Yeah, I kept watching the install video for the Mishimoto and was thinking that I'd have to follow those instructions. But the Mountune fits pretty neatly without being a total PITA.

It did not seem like a Pita when I did it either. It actually went pretty fast. It was really nice to actually be able to mount the shroud and radiator on the support and then put it back on the car. Lol
Though ya if not for the intercooler I probably would have done what you did.

Per the Ford Service manual the fan shroud should come out the bottom and the radiator comes out the top. I suspect that following the Ford procedure may provide for a bit more clearance.

However it is good to know there is an alternate in the event whoever wrote the manual was a complete idiot. BTW having worked on the automotive supply side since 1982 I have to say I am NOT at all impressed with today's "engineers". So it's very possible this section of the Service Manual was done by someone fresh out of college who doesn't even know what a Ratchet is. So alternate approaches are a GOOD thing.

That's funny. When I was working on it, it didn't seem like there was enough room to get the fan out from the bottom but I could see how it might work. There just seemed like fewer things to get stuck on when you bring it out from the top.

With the radiator, there is the AC bracket behind the radiator on top that would make taking it out the top a little more tricky. You'd have to squeeze it in between that bracket and the shroud covering the radiator and I could see that that would be pretty tight.

I agree with you on the "engineers" write ups too. I like to read those first, but there is so much good information in communities like these that can often save you some headache.

I have the stock thermostat. But while waiting for the car to warm up, I felt the upper hose start to get warm once I crossed over 180'.
