This problem is still happening. I am getting an aftermarket temp gauge installed so I can see if it might just be erroneous readings from the stock gauge. I had th compression tested, as well as the test for exhaust gases in the coolant to see if is the head gasket, they both were negative. It is not leaking any fluid. I have found several threads on this forum with exactly the same problem, without any conclusion, so I'm not quite sure what to look for next. Again Ive switched out all the cooling system to new. I was unable to find an aftermarket thee row radiator, so I had to go with the stock two row. Ive tried 3 thermostats, and am currently running the coolest available, a 160 degree. he runs cool for about ten miles or so, depending on the outside temp, then heats right up to the top of the "normal" range, even slight higher at 65MPH on a hot day, without any hills. I have had the shop make sure they bled the air form the cooling system, then I got a sealable funnel and tried it myself a couple times. Pretty sure air in the system has been purged. I should have new temp gauge in next week. I was excited about buying this rig two months, ago, now pretty disappointed.

I drove a VW camper bus for five years with no heat or AC, then a big Dodge Camper for 8 years with no AC. I have been using a Toyota Previa van with AC for camping for 12 years, and there's no way im going back to sweating my behind off in the Eastern Washington desert or anywhere else without an air conditioner.

I get your point. But AC is a priority for me for sure. I was planning on having it fixed from the beginning, since I only paid 2400 for the rig to begin with.

OK, I went to a mechanic with a good rep and a great shop in town that works on a variety of rigs. He said he is sure it is NOT the head gasket. I was going to have him work on the rig to get the cab AC going again. he said it looks obvious to him that AC condenser, which sits in front of the radiator is totally clogged with leaves, bugs and other debris, and that is why it is running hot on the freeway and not at lower speeds. He said that would not be the case if it was the head gasket. The condenser is toast anyway, as it is leaking. I am on vacation next week, but when i get back, I am taking it in, he is going to get a new condenser (this one is actually no longer available), but were going to look for one that will fit. he seems confident that once a new clean condenser is in place, I should have no more problem. I'll keep you posted if that is indeed the case. I hope so.His shop was the one I had do the new radiator, fan clutch ( which WAS not working) and water pump right after I bought it a couple weeks ago. It had run warmer than normal on the freeway drive from where I bought it 130 miles away, and I wanted to totally rebuild the cooling system to start with, as it was the original radiator. I got the rig for 2400, and planned on fixing as many things as I can with my budget.

Like I said it has a brand new fan clutch.

Anyone else have an odd issue when your 22RE engine runs very hot on the freeway, but OK at lower speeds? Even in cool outdoor temperatures?My 88 Dolphin has brand new radiator,fan clutch, water pump and thermostat.It is running at the very top of the normal range on the temp guage(right on the upper white line!) while on the hiway at 60MPH, when it is about 60 degrees outside.If you are driving on a secondary road at 45-50, temperature is much cooler.I have looked at a few threads on various Toyota truck forums, looks like this is not an uncommon problem. I've seen explanations of using a thermostat that has two vent holes specifically designed for this issue, and that it related to air bubbles in the cooling system that need to be "burped." Anyone else had a similar problem? Here's a link to a thermostat that was recommended http://www.4crawler.com/4x4/CheapTricks/index.shtml#Thermostat Im gonna check the actual temp with a laser temp gauge at the thermostat this week, in case its just the gauge giving a weird reading.

Wow, thanks Derek! Good info! Do you know if there is any info on line about the bathroom equipment on my dolphin? Just trying to figure out how the toilet works. If not I plan to take it by an RV pace, to ask some questions about my water leak and what I need to do to get the toilet up and "running" as it were.

OK, good info, Maineah! I'll see what I can find leak wise, Like I sad when the water tank was partially full I saw no evidence of leakage. Do you know if this website has any documents scanned up for operation of the systems, like the toilet, stove.overn,etc?

Hi folks, This is my first post. I just aquired a 1988 Dolphin, I'm pretty excited about it, can't wait to fine tune a few issues before using her this season. I have a water leak issue that I'm guessing is related to the drain on it. The main water tank had some water in it, enough to be able to turn on the pump and get some water from the cold water faucets at the kitchen and bathroom sinks. The remote sensor lights showed a minimum amount of water in the tank. Today I decided to fill the tank, and ran water into the inlet until it started to come out of the small vent hole. It checked out as full with the remote senor light.Shortly thereafter though, water began leaking under the vehicle, right where the hot water tank is located.I tried to locate a hot water tank drain cock of some sort under the sink area, but wasn't really sure what to look for. I then drained a few gallons out of the main water tank, and that seemed to stop the leak.It wasn't until I was changing the oil a bit later in the day did I notice it was pretty wet on the carpet at the drivers seat. I used a shop vac, and managed to suck up maybe a gallon or two of water from that area. I drained maybe another gallon from the main tank, but at this point,I can not see any more leakage from anywhere. Can someone direct me first to where the drain for the hot water tank is? If I can close that, then I can look for any other type of leakage. The rig seems to be well cared for, the shell may need some waterproofing work at some point, but it seems like many systems work. The fridge is fine for one thing, as is the stovetop, and waterpump. I have the general Dolphoin manual, and the one for the fridge, but no paperwork for the water heater or bathroom stuff. Are there some manuals on this cool website? Thanks in advance for any info you can provide!!! Steve
