1991 SAAB 900 radiator replacement

I have been smelling that sweet smell of antifreeze burning for a little while and while never seeing any on the ground from a bad water pump I knew it was time as the 25 year old cooling system is showing its age. I recently got the foot drip of the old 900s as well but the heater bypass valve is back ordered on www.eeuroparts.com at the moment so I started with the radiator.

Starting disassembly:
  • Disconnect battery 
  • Drain coolant



  • Unbolt your turbo to intercooler pipe clamps and remove
  • unbolt your ignition coil 
  • vacuum control valve ( next to coil brown valve, thing that clicks when it goes bad)




  • Remove the torque screws holding in the fans ( T20 screws 2 upper, 1 lower) and unplug and lift out
  • remove


  • take of overflow return hose, Driver side
  • un plug fan temp sensor , Driver side
  • upper radiator hose, Passenger side
  • lower radiator hose, Driver side
  • unbolt 2 radiator bolts 
  • tip back ( toward engine ) and lift out, radiator has two posts on bottom that go into rubber bushings 



  • drop in the new radiator 
  • reverse directions to reinstall 
  • fill coolant and reconnect battery
  • run through warm up and make sure your fans still turn on

MazdaSpeed 3 2008 Idler / Tensioner Pulleys and Belt

Changing the idler pulley, serpentine belt and tension pulley on a 2008 MazdaSpeed 3 is quite easy ( I do not know if this all applies to the regular Mazda 3) and can be completed in a couple hours. I got all my parts from Napa www.napaonline.com  / good luck 1. Set the e-brake 2. Loosen the Lug nuts on the Front Passenger Tire 3. Jack the front of the car and support on jack stands 4. Remove the front Passenger tire 5. Remove the bolts that attach the small plastic splash guard toward the front of the fender well ( this gives you a bit more room for getting at the idler)  (A view from the top of the engine bay) 6. Use a Combo Wrench on the Tensioner Pulley to slack the belt and slide it off the pulley (Turn the wrench Clock-Wise to slack the belt, note that there is a notch so that the Tensioner can only rotate so far so do not exert the Tensioner beyond the point it feels it stops rotating) 7. Remove the two bolts that hold the Tensioner to the Engine Block 8. R

2008 MazdaSpeed3 Purge Valve Replacement

Purge Valve Replacement on a 2008 Mazdaspeed3, I recently was having a hard start after refueling, the car would start and idle at 500 rpm and barely run and would stall but would restart and with a quick gas pedal press it would run fine once it idled out. So I googled a bit and found that it was the purge valve.  I bought one from AMAZON.com  the Dorman 911-702 Mazda 6 Purge Valve Start by removing the Inter-cooler Cover Screws and the plastic guard. Locate the Purge Valve (in between the inter-cooler and the battery box) Remove the hose guarding to get to the clamps and remove the power connector to the purge valve Remove the Hose Clamps and slide off the Purge Valve The rubber mount will not be in the Same Orientation  Remove the Rubber mount from the new one and align to be the same as the one you just removed Re-install in the reverse order and Enjoy your speed again Amazon Affiliate Links used in post:
