Anyone got any handy hints and tips on changing a GTV's radiator? Going to attempt it this weekend. Think changing GTV radiator for dumbies.
I changed mine recently, a P1 without Aircon, very easy.
Remove Top and Bottom Hoses then dry feet.....
Have four new 42mm good quality Jubilee Clips to use if the old ones are shot.
Remove the Phillips Screws nearest the centre of the Car that hold the Plastic Covers that cover the Headlights, this will give you plenty of slack to remove the Slam Panel.
Remove the Four Bolts holding the Slam Panel and remove the Panel.
Looking from the Front you will see the end of two Bolts with the " Clip On " type of Nuts. Access the Head of these Bolts from the Engine side, for the Passenger side you have to unclip, by pulling, a little hinged retainer clip on the Plastic Cable tray thingy ! Remove these Bolts and be aware that the " Nuts " will almost certainly break and you will probably have to hold the remains of these with a pair of Mole Grips whilst removing the Bolts. Have new Nuts to hand.........
Did I really say that !
DO NOT remove the two very obvious Bolts that hold the Radiator in.
Remove the Cable Tray thingy.
Unplug the Fans and move the Cables out of the way.
Now remove the Fans by pulling them up, a fair bit of force may well be required as the bottom of these just push/clip into the bottom of the Radiator and they will almost certainly be pretty full of gunge. Go on, give it a good pull ! When they do come out, and they will, make sure you have the two rubber sleeves that fit on the bottom of the Fan Assy, clean these up for reuse.
Now remove the two Bolts mentioned above and then lift the Radiator out from the top, ensure that you get the two rubber grommets that the pegs on the bottom of the Radiator fit into it, clean and retain. The Bonnet release cable is a bit in the way but no real problem.
At this point it may be a good idea to derust, clean and paint the Bottom Cross member that the Radiator sits on.
If required fit the Blanking Plug to the unused Hole in the Radiator, take care with this and ensure that it is watertight and that the " O " Ring fits correctly, do not overtighten. ( I had trouble with this, there are two types of Blanking Plug, one with a groove that the " O " Ring fits snugly into and one that doesn't, guess which one I had first....
Fit both Hoses to the Radiator, the Pipes have " slots " in them so you can't get the orientation wrong.
Fit the two Rubber grommets to the pegs on the Radiator, a bit of gasket goo or similar will hold these in place.
Refit the Radiator and put the two Bolts in.
Fit the two rubber sleeves on to the Fan Assy, again using gasket goo and refit the Fans and the Cable Tray using the two Nuts 'n Bolts.
Refit the two hoses to the Engine.
Reconnect the Fan wiring.
Turn Heater Controls to " Max Heat. " Fill up the Expansion Tank with Coolant and then open the Bleed Screw on the top left engine side of the Radiator, looking from front, until all the air is expelled and the Coolant comes out. Top up the Expansion Tank as required, you may need to top up again over the next few days until all the air is out of the system.
Check for leaks. If none found start Engine, check for leaks. If OK let engine warm up fully and check that the Fans operate correctly, keep looking for leaks during this process.
If all is well have a cuppa and a cig and then refit the Slam Panel, job done.
Sounds a lot more complicated than it is but I must stress that I have no idea if this guide would be the same for cars with Aircon.
Before starting it's a good idea to spray WD40 around all the Nuts 'n Bolts the day before.
You could take this opportunity to fully remove ALL the old Coolant and flush the system, that's up to you.
If your old Radiator was really bad you will see that the Engine will run a bit cooler than before.
PS. If you don't drain the whole system you will need about 4 Litres of Coolant, if you do drain and flush you will need about 8 Litres,
Good Luck !
