You should drain the system first before unless you like coolant

on the floor. You should actually replace the whole housing,

it's old and dry and will cause future problems. It only cost me

100 CDN for all seals, 3 housing pieces.

1. Remove the 3 hoses that are attached to the housing.

2. There are 3 bolts holding the housing on. Two long ones and one

short one that is close to the head.

3.Now sand the head lightly to remove any old deposits. It should look shiny

after. This is to make a better seal.

4. Now put everything into your new housing. I used some white grease on the seals for

he 3 sensors, the themo seal, the seal that connects to that plastic hose and the head seal.

Now i put some blue gasket stuff on the head seal and in the housing where the plasitc hose goes.

5. Now when replacing the themostat make sure that bleedvalve goes back in the same way. It is that

little nipple on the stat.

6. Tighten down all the bolts on the housing and place back into position. Make sure you tighten all the

bolts are tightened down evenly or else you will see leakage.

7.Replace the hoses and top up the coolant.

Done.
