coolant

My coolant is going to another dimension or stolen by my neighbor every night... 95' Land Cruiser FZFE, imported from the middle east. 77k original miles, my daily driver. Engine rebuilt in 2025 to include the head gasket. New radiator, new plumbing. Passes pressure checks, no leaks, combustion...

Hi everyone, I have a 2003 Land Cruiser (100-series, 4.7L 2UZ-FE). It’s around –35°C outside. The cabin heat is not working (blows cold). The coolant reservoir was empty and I refilled the radiator, but there is still no heat. When changing HVAC modes (feet/defrost), I hear a ‘tuk-tuk/clicking’...

Hello, After car is warm, coolant gauge starts to rise randomly then quickly drop back to normal. After driving for a while, hitting the gas will cause it to go up, but letting off the gas will bring it back to normal. This just started happening Parts replaced before the problem...

Hi all, I have a 2004 Gx470 with over 250k miles. A few years ago It overheated on me once and come to find out it was low on coolant. Filled it up and forgot all about it. Flash Forward to earlier this week when I got out of the car the coolant over flow was steaming. Didn’t have any thing...

Hello, I was just replacing my coolant when a bug flew in. It was smaller than a fly, a pretty small bug, maybe a little bigger than a gnat. I'm worried about future damage and plugging of passageways that could lead to damage. Should I be concerned about this, or is it no big deal? I would...

At the end of a road trip in pretty mild temperatures (around 60F) the radiator hose connected to the engine exploded sending coolant everywhere. Completely shocked because I checked the coolant levels before we left and I have a 4 year old radiator with additional cooling block attached...

For the last 2-3 days I have had this small leak on the passenger side of the car. I've had to refill the coolant fluid at least three times in the last few days and the car has began to over-heat. Today I got a chance to check all the hoses and the radiator - everything looks dry as a bone. I...

I recently took a road trip that included the desert areas of SE California and West Arizona. I saw ambient temps between 105 and 117ºF [40.5 to 47.2ºC]. My engine coolant temp (viewed on ScanGage) varied up to 204ºF [95.5ºC] under high load (climbing, AC on). Under lower loads (descending) the...

I have set aside this wonderful 4 day weekend to finish the overhaul of the coolant system. I restored the rear heater and got the fan working. I removed the front heater today and began thinking about all the wasps nests that we, as FJ40 aficionados, have discovered and removed from the many...

Hey there H8'ers, Here is a synopsis of what has been going on for the past few months on top of my current no-start problem. It has heated up HOT on multiple occasions. I always have coolant on hand for this reason, BTW what do y'all use? Anyways, I try to be as vigilant as I can (especially...

Hey all, Title says it all. Basically my LC engine was making a squeaking sound when the engine got warmed up. Then the higher the rpm's the faster the squeak got. I took it to a local shop here in Austin, explained the symptoms to the mechanic. Coincidentally on my 16mi drive to the shop the...

Hello! I'm a pretty new Land Cruiser owner and getting to know this vehicle has been super fun but I've never worked on cars up until now. I have this coolant leak that starts going wild very randomly but when it starts leaking, it goeeeees... I believe I found the source of the leak but I don't...

Been scratching my head over coolant plumbing after de-smog. I got MAF headers, and their heat riser to apply to the underside of the stock intake manifold. I'm being told to supply the heat riser coolant from the heater valve on the firewall, which is supplied by (or returns to?) the steel...

My mechanic was doing some repairs on my 1995 TLC and he noticed some dirty oil in the bottom of the side coolant reservoir. (I think that this is the part circled in red in the attached photo). He wasn't sure how this occured, or if it means that this is a sign of a bigger problem with the...

Can anyone please help me locate the coolant block drain location on 2B. I've searched exhaustively in MUD and an online and I've found schematics that show the location but I can't find it. I've creeped all over from every angle. I'm sure I'm looking right at it and not realizing. Found...

Hi guys! Newbie to this forum. I have a 75 fj40 that has been restored. After driving it and it sets for a few minutes, antifreeze leaks out of the reservoir drain hose. Any ideas on why this happens and possible fixes? Thank you in advance.

We have a '73 FJ that runs really cold for the first 5 minutes. It has a 2F engine in it with a rebuilt Holley 2 Barrel carb. I have to start it and let it idle for about 5 minutes to get it to run right. It is almost like it is being starved of fuel. Once it is warmed up, everything is...

Hello folks. Been experiencing variou coolant leak issues after having my timing belt changed a few hundred miles ago in December. Almost immediately after I picked up the cruiser after the timing belt/water pump job, I noticed a consistent leak under the rig. Turned out that the water inlet...

All, I am inspecting a possible '04 purchase. The truck had a timing belt done about 15k miles ago and clearly the mechanic used green coolant. Ignoring this fact I noticed some potential leaks in the following areas. Whatre your thoughts on the sources? I'd hate to buy a truck and have to go...

Title of the thread states it all really. Whilst diagnosing fuel/starting issues, I've come across 2 wires. one being white and the other being green, and it's a 2 pin plug. The plug in the water outlet housing is fine, nothing wrong with it, but its just the other end, wire have either been cut...
