Bouncing temp gauge

I got the bouncing temp guage problem that I've seen on here b4. From what I've read it's from the wrong thermostat having been put in (not by me). Now whats to be done to fix this? Just rip off the thermostat housing, replace with the proper thermostat and get a new gasket and put it back together? Will much coolant come out? And then is it just a matter of refilling the spilt coolant and going for a drive to get the air out of it?

Also is the EL housing a direct replacement - no mods to hoses or anything? And what are they worth?

And what exactly is the correct thermostat and what is the costs - around $30 I assume..

correct thermostat is 91degrees costs about $20. I never bothered with the gasket and never had it leak. you will need to refill with a few hundred mills of coolant.

a double acting 91 degree thermostat...

a gasket can't cost much tho to do it right..
for the sake of $50 i just might go to a shop and get em to do it..

what would be the consequences of leaving it like this? thermostat have a higher chance of stuffing up before the next radiator flush from opening and closing too often?

Could get away with drilling a whole in thermostate.

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

Drilling a hole in the thermostat is the only solution ive found, ive tried just about ever brand of thermostat and they all cause the temp gauge to fluctuate, the only one that didnt was a 77 degree one.

About 1/16" should do it, make sure it is at the 12 o'clock position when installed as it will also help as an air bleed.

Make that the 6 o'clock position, as the front of the motor is the highest point, therefore the hole should be at the front.

The hole is the only way i've managed to stop mine bouncing also, but it does initially take a long time to warm up.
