thermostat housing

I just replaced my water pump and thermostat among other things. I fired it up today to find coolant was leaking out of the driver's side lower thermostat housing bolt. Is this a common occurrence? What would the fix be? I did apply a small amount of FIPG to the threads prior to install. I think...

First sample received today. Will test fit for compliance. Very happy with it. I've had these made out of a better Alloy than the original. Will last longer. More tolerant of additives etc.

Really exceptional good shape. No pitting on the hose connections, both bolt holes intact, and the rare METAL BVSV that you don’t have to worry about breaking the nipples off of. $200 plus the ride.

Good shape just dirty. $20 plus shipping.

Anyone know the PN for the thermostat housing gasket? I'm looking for the square o ring looking thing. Thanks, Jim

Hi, looking for a lower T-stat housing for our 1977 FJ40 (build date October 1976). Bought new OEM lower housing but not the right one. Need one with the BVSV port. Ours is pretty roached. If anyone has one in good shape, please let me know. Also, If you need the OEM housing I bought, we could...

New modern progressive 2F 3F 3FE thermostat housing assembly hardware is here in 2023 , state of the art features and needed upgrades JAPAN Spec. .... finally ...........:rolleyes: . . ...

Rebuilding a 2F motor in a late ‘85. In the lower thermostat housing there are 2 sensors. One is a switching valve and the other I thought was a coolant sensor, but doesn’t look like the replacement parts. Anyone know what this sensor is? While removing this unknown sensor, the thread pulled...

Been chasing a small coolant leak, its puddling on top of the thermostat, around and behind the bypass hose connection and we are loosing about 1/2 gal in a month. I originally changed the 3 o-rings for the small pipe that goes to the head. when that didn't work, i changed the bypass hose and...

Hi all! Another baselining question but this time, it's with the cooling system. I've gone through a bunch of threads regarding the updating of the cooling system but I didn't see anything about the water inlet/outlet housing... QUESTION: If I'm going through everything in the cooling system...

It seems almost every thread regarding thermostat replacement on the 3FE is accompanied by a lengthy saga of extracting broken bolts. I've got a handful of bolt extractions under my belt now, and I would like to avoid it here if at all possible. I've got a thermostat in hand and have been...

Picked up a couple of these awhile back when a limited run on here got done. No longer need this one. 175 shipped

Thought I was gonna replace the thermostat gasket but nope… Can someone tell me about replacing this gasket/resealing this part? I have no idea what you call that hole so I don't even know how to search for it.

Hey guys, I am currently in search of a Cold start timer switch (8946220040) that will fit on my 89’ FJ62. Just bought the Cruiser and that piece is broken. Only having a problem finding this part, but if you also have the Thermostat housing lower (16333) and Thermostat housing gasket (16343)...

Hi all, Just finished changing the following on my 88 FJ62. All parts are from CCoT. water pump hoses belts thermostat aftermakert dash temp gauge sender radiator cap pretty sure all is burped sufficiently but not 100% certain. No leakage Despite being a bear of a job, it seemed to go well...

My water pump blew up (coolant everywhere) at the end of last year so I replaced it and all the hoses. While I was doing that I tried to take the thermostat apart and sure enough, both bolts snapped. The FJ went into storage over the winter and there was a tiny bit of coolant under it every time...

So I have begun replacing parts on my cooling system starting with the radiator and all of the radiator hoses. Today I decided to take apart the thermostat housing, and to my surprise there is no thermostat. I have had no issues with my engine running cool, it typically holds 180* on long drives...

I replaced the upper thermostat housing in my FJ62 with an aftermarket housing and now am having an issue with the stock water temp switch leaking when engine gets up to temp. I read a few threads saying teflon tape is a no no, as the switch is grounded through the threads. Searching the stock...

Hello, Looking for FJ60 (1985) Top thermostat housing (isn't it the same as a late model FJ40)? Four bolt holes. Anyone have one? Need it shipped to zip code 30265 Thanks!

Redoing the plumbing on my 2FE and trying to decide which housing I'm going to run for the thermostat. I have a question about the 2F with oil cooler: In this photo, cool water is flowing FROM the water pump -> oil cooler -> thermostat upper housing, correct? I don't really get that...
