Rem

My check engine light came on my 2007 mazda 5 and found out that i need to replace the thermostat. Can someone tell me how to change it so i dont end up trying to do it my self and messing something up.

 

I found this image and maybe this will help you identify the thermostat location so you don't have to pay the dealership like I did because at that time I did not find this picture. If I did, I will not go to the dealership. Please someone correct me if I'm wrong, number 23 is the thermostat.


Procedure that I got from another Mazda Forum:

1) Drained radiator from drain hole on driver's side of radiator - a little over 1 gal of fluid
2) Removed overflow tank (empty & clean) and all hoses from radiator neck for hand access
3) Did not remove tensioner belt as in manual - not needed
4) Thermostat has three 7mm bolts - used 3/8 ratchet with 1/4 adapter & 6" extension - fit perfectly. Removed 1 bolt from top, 2 bolts from bottom.
5) Thermostat has 2 hoses attached - 1 large, 1 small - these are pain to get off. I traced small hose to engine - removed small hose from engine(don't pull off hose with face under engine & mouth open :-). With small hose removed, was able to bend large hose so that thermostat is under engine - then able to remove both the small & large hoses from the thermostat. Thishttp://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER would really help in getting off the clamps.
6) Note that markings on hose - align with marks on thermostat. Attach large hose to thermostat under engine, then small hose. Push thermostat back to original location.
7) attach small hose to engine
8) bolt back thermostat - 2 from below, one from top
9) hook backup hoses & overflow tank
10) flush radiator
11) refill radiator & you're done
12) check for leaks
