      My co-worker came to my car this morning (9/20/2014) before work and said “You’re good with cars, I need help” she happens to have the same car I do, and I noticed her radiator appears to be leaking, and I’ve got an Idea of how to replace it, but not sure exactly where things are, and the areas of common rust are, she is raising a few young ones as it is and is on a very tight budget for this job, I’m having issues finding a video on how to replace the part on this model year. She’s a good friend and I want to do this right, with as LITTLE breaking and mistakes as possible. Any hints or advice for me to make it a clean job? Or a video link to a similar replacement??? Any help is greatly appreciated! Also…. is it worth it to replace the hose clamps to the screw type…? Sorry, while typing it I was thinking that I already said it lol… 2002 Pontiac Sunfire 2.2L OHV engine, 8th digit in VIN is a 4. Some things matter for the VIN

        Maybe you can edit your original post to contain crazy little details like the year, make, and model of car we’re talking about… :stick:

            If you get a Chilton or Haynes manual that will probably tell you what you need to know. Here is a listing for the Haynes manual:

            http://www.haynes.com/products/?searchType=vehicleApplicationSearch2&searchEnd=yes&sfID1=&sfID2=&sfID3=&year=2002&make=Pontiac&model=Sunfire&x=15&y=7

            They also have online manuals for sale. I prefer paper. Since both of you have the same car this book may be extra useful.

            For replacement radiators I have always done well with Modine. If those are the original hoses they should also be replaced, finances permitting.

              Thanks so much! I’m an idiot, (Half asleep) I have a service maunal, I didn’t think to look. I will read it, I feel dumb now haha, Thanks though. I’m gonna read it a few times to get a perfect idea. I’m heading to bed though, have a good night. I won’t refresh the page anymore tonight so I won’t see any replies until tomorrow night so if you don’t want to, don’t reply. Waste of time and effort typing 😛 Cya!

                Sadly, the manuals never seem to mention the problems you will run into. Count on it taking longer because of this.

                Also, avoid the temptation of using a radiator out of a junk yard car. There is a good chance the one you find at the junkyard will have the exact same leak.

                Most radiators are not real difficult to remove. the likely problems you will have is – it gets messy. No matter how well you drain it ahead of time, about 20 more gallons of antifreeze will leak out of the cooling system. Usually in the exact spot you need to lay on the ground to work. That and bleeding is kind of time consuming.

                Also – the lower mounts are probably going to be made of rust by now. Don;t forget those rubber rings it probably has in the mounts. Replacing with screw type – Those are easier to install than those damned spring clips but do not overtighten. Do not know what the torque is but you don’t want to overstress the flimsy plastic radiator necks.

                        My experience is that the hose clamps that are a one piece spring steel are the best and if that is what is on the car reuse them. They stay tight as the rubber hose underneath shrinks and compresses. Wire clamps with screws – discard them. Worm drive clamps are okay but need to be tightened periodically.

                          If I do replace a clamp, it’s usually the one on the lower hose. That one is difficult to access after the job is done. For the most part I don’t find it necessary though. It doesn’t hurt to be prepared however. That said, this is not the same make and model but it does cover some basic tips on radiator replacement though.

                          Good luck and keep us posted.
