Renix to HO Swap Question

[Newton]

Recently did a renix into HO swap Noticed temperature fluctuating thinking might need to burp the system properly as i didnt drill a hole for the temperature sender in the back of the head is there any other procedure to burping system other than the sending unit location in the back of the head?

I've had quite a few HO's and never had a problem with burping them. That goes for the 96's and up too w/o the head temp sender bung. Try letting it sit overnight with the radiator cap off. All the trapped air (if that's your problem) will work it's way out. 

 

Also, what are you using for the HO expansion tank? Are you still using the Renix closed system stuff?

Yes still using all the renix stuff didnt have any overheating issues with the old renix engine all i did was swap out the long block everything else is the same so I'm guessing the issue might be air trapped in the system since i didnt really do any burping procedure just poured coolant run it for a little bit and topped it off

Remove the upper hose from the radiator. Fill with coolant through the hose if you suspect air.
