Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I am considering going to a cooler thermostat - is the housing DIY accessible, if os where is it???

POST 2Original post

<Smart a@@> If you wait a while your old one will cool down all on its own... and how the would I know where you left it Do you have the PET? If not PM me your email and I will fire you off a copy. It helps me "see" these things and where they are located, the part numbers and then finding a cost off Renntech - also do you have the manuals? I can point you to those too. E

...does that schematic suggest that the t-stat is somewhere to the top-left of the water pump and oriented 90-degrees to the pump?

POST 5Original post

Yes, the thermostat is on the left rear corner of the engine (as viewed from the back) and is in orientation to the water pump as in the diagram - at 90 degrees (meaning it bolts on the side of the engine) and is roughly in line with the back header tube. The themostat center is literally feeding the impeller of the waterpump (within inches). You can see the thermostat from under the drivers side of the car - head under the muffler (roughly). The top bolts of the thermostat are difficult to access - I was able to access with a long (12"+) 1/4 inch drive and a universal joint - 10mm bolts The toughest part is removing the large rubber "radiator" hose from the thermostat (considerable wrestling) which required removal / loosening of some of the other smaller coolant lines including the steel lines on the bottom of the engine and waterpump outlet hose. Remove the small lines first to gain "pull room" for the thermostat hose. The large outlet hose of the thermostat is constrained by a steel line and a rubber hose that T-s near the corner of the coolant tank. You can see this interference and most of the required work (and thermostat) fairly well with the air box removed. Look staight down on the left rear corner of the engine. Remove all coolant first with the small plug (same look and type as oil drain plug) on the rear coolant passage of the block. See Rennlist for DIY of airbox and coolant removal. Good luck if you decide to tackle. Marlin
