Thermostat fix

[buckleywarrior02]

I'm swapping out my thermostat and need help with order on putting everything back together. Is it gasket, thermo, housing? Thats how I did it the first time and it leaked like crazy. I need to get this fixed soon cause its starting to cool down out here and the bike may be getting put up soon. Thanks

Thermostat & Housing Replacement in a 93

Source: by Kevin L at kevin-long.tripod.com

he uses silicone... - get the stuff for t stat/water pump sealing...as Mark wrote:

"Installed a new 195 deg thermostat & gasket. Cleaned thermostat housing - A dremel and steel brush attachment made short work of cleaning the baked-on remnants of the old gasket and crud buildup.

Installed new "bypass" hose and clamp.

All surfaces were sealed with Hylomar HPF gasket sealer. You can actually see it in the photo - the blue stuff that is squeezed out around the edges of the housing."

and by my pal sixlitre:

"Get the new peel and stick T-stat gasket

Discovered this doing my water pump change a few weeks ago. Like Rick3373 says the T-stat can "walk" out of it's sunken ring and come unseated as you're tightening those wonderfully easy to get to housing bolts.

This not only crushes your T-stat outer ******, it won't let the housing sit flat to the intake and leaks can happen.

When you've cleaned everything up, put the T-stat into the housing's ring and then stick the sticky side of the gasket to the housing, securing the T-stat to it and that way it cannot fall out during tightening. I use a little sealant on the non sticky side of the gasket where it mates to the intake.

***** Big tip As the T-stat housing corrode the actual snout where the big hose clamps to gets porous and may leak, no matter how tight you twist the clamp. I had to buy a new housing when I did the pump.

The dealer wanted $164.00 CDN (ha hah ha), but only $30 CDN for the new chrome Motorsports unit. Had I known this I wouldn't have bought the $20 CDN off-shore cast iron POS I did."

ck housing for cracks... GL!

I am real fond of having this stuff around it sticks real well even if you can't get all the oil and or water off. Most Auto parts places have it.

Just changed mine, I use a very light coat of RTV Blue on either side of the gasket. Put the t_stat into the water neck, light coat of RTV (after cleaning both surfaces; the water neck and the intake), attach the gasket to the water neck, light coat of RTV on outside of the gasket, attach to intake. Never had a leak using this method.

This also a good time to replace old hoses and flush the system then replace the coolant with fresh new stuff. Put the antifreeze first and then top off with water, could add a bottle of water wetter too.

Good luck,

OK, great! I've been using the blue RTV, so I think I'm doing it right. The only mix up I have was placing the gasket before the thermostat and i think thats the problem. Thanks guys!
