overheating

Hi Everyone, This is my first post, and I'm new to the forum. Been lurking and reading for a long time, but finally decided to post. A little about me, my daily driver is a 1985 Toyota Pickup SR5. I live on a gnarly mountain road, and this billygoat gets me around no matter what the weather...

Hi, First time poster from Austin. I have a blue April 76 FJ 40 (pretty much stock and still smogged) that I've owned for about 25 years, but I put it up for the last ten years. I've gotten it back out and am going through the mechanicals and electrical... lights, fuel lines/gas tank, brake...

Hey friends. Left my 2001 lx470 (97k miles) idling for a few minutes. Overheated and then the Heater t busted, or the heater t busted just because it’s old, not too sure. My neighbor turned the truck off, but he said there was smoke everywhere, etc. not sure what damage was done, but I replaced...

I bought my FJ62 in 2010, and have had overheating issues. Right off we diagnosed a blocked radiator made for high temperatures when you go above 2000 rpm. I had the core rodded out. Soon after the top tank started leaking. I had this resoldered near Timbuktu, again in Benguela in Angola, used...

Struggling to find a FSM for a FZJ105 4.5L I6 gasoline without distributor. I think I have a timing issue and my mechanic has been unable to solve it. All I can find are manuals for the V8 100 series or the I6 80 series with distributor. Following a head gasket install, I am overheating and...

I want to compare the head gasket that I can find locally here in Peru with the upgraded OEM head gasket. Unfortunately Toyota doesn't carry it and don't really want to wait a month to get the part shipped from USA if I don't have to. Oh yeah, the head gasket slowly surrendered while on what...

After years of wanting one, I finally picked up my first lc. It is '91 and definitely a project (I don't think the previous owner ever thought about maintaining or fixing anything on it) but I am enjoying bring in back to its former glory. Anyways, a few weeks ago I took the rig up to the...

Hi all - I'm still relatively new to the cruiser world, but my JDM HJ61 has recently started overheating - well really, running on the warm side, which is a new occurrence -- and one that I'd like to stop. I've done my damndest to figure out what's going on (using the search function on MUD) but...

Recently, had a cold snap in these parts. A bit below freezing for a few days, snow & freezing rain. Chose to drive the Cruiser, due to conditions. Wasn't worried about the temps, as I knew I had ample antifreeze. Drive slowly over big hill near start of my commute. On the downhill, notice wisps...

I thought I'd share a discovery I made that was revealed by some testing. I've had suspicions about this for a long time. When the coolant is drained and replaced on a 2F, an air pocket gets created inside the sender's adapter fitting which prevents the sender from being fully immersed in the...

As a follow-on diagnostic to an ongoing engine coolant overheating problem, coolant system pressure has been a question. So, I've finally gotten around to rigging up a radiator / coolant system pressure gauge that can be monitored while driving around at speed, rather than just guessing and...

So, I've been having overheating problems. It's a familiar story if you read here much, and other forums, too. I could recite the same litany of "did you check this, did you check that" from Isuzu diesel conversions (Wheelingnoob - sheesh! It was like reading "Lord of The Rings") to Subarus to...

Hello everyone hopefully someone can help me. I just got a 1990 4Runner with a 22re in it. The engine was rebuilt and has only 50,000 miles. When I purchased it I drove it about 2 hours on the Interstate (70 mph max, 5th gear, 3k rpms) with no trouble until I stopped at my destination. Then it...

Still doing some diagnosing today, but we took the BJ74 down to Vegas on Saturday...got about 30 miles out and it overheated. Temp gauge was pegged, steam from the overflow. We were driving 70-75mph with a mild headwind on a cool-ish rainy NV day. @Mace rescued us - THANKS! System was "dry"...

I'm a total noob here, so bear with me! About a month ago I was letting my cold blooded FJ60 warm up for about 20 or 30 minutes (it was frozen solid, only about 5 degrees outside). When I came out I noticed a large pool of coolant under that car. It took me awhile to locate the leak because...
