This has been happening since I swapped coolant lines. I've had a few times where the coolant would push out of the cap while driving after being on the highway for a while. There is no overflow tank like the Vanagon. I'm using the pressure tank from the donor car-a '98 Jetta. I've used one of those testers a couple times and not gotten indication of combustion leaks, either. I'm fighting similar problems in my '78 Bus with TDI motor. I'd like to hear if you come up with anything. Posted: Mon 9:16 pm Post subject: Re: Subaru conversion van with coolant overflow tank problem I basically 'burped' the air out over time but such overheating *can* ruin the head gaskets. I have a vanagon with subie 2.5L with the same problem and that's what it was.

(FWIW, I had the same thing on the OEM VW 1.9 which caused me to put in the Subi 2.5 THANK GOD!!!)Ĩ3.5 Westy with Subaru 2.5, 4 spd manual, center seat, COLD A/C on 134a!, Winter camp heated with an Espar B4 gasoline furnace You may have to have someone back there whil you stress the engine. And possibly it onl y shows under high loadĪs much as you seem to want it to - the conversion kit cant fix (or prevent) a bad head gasket.īorrow one of these from your FLPAS and solve the mystery.

The coolant has tested negative for combustion gases three times in the last two years (most recently by the Subaru dealer). I removed the radiator cap to find that my coolant level was low, so I poured back in the coolant that I had siphoned from the overflow tank during our trip. When I started her up this morning, the coolant level indicator light started blinking incessantly. I let the van sit for a day after our trip. I average around 18-22 mpg around town and got 18 mpg on our Saturday drive. I’m running a 50/50 mix of Prestone antifreeze. The temperature gauge needle sits rock steady in the middle of its range. The van drives great, has impressive power, and does not overheat. When we got home, coolant in the overflow tank was about an inch above the maximum line. I siphoned enough coolant from the overflow tank to get it back down to the maximum fill line and drove back home without incident.
#98 subaru coolant pushed into overflow full
So, the overflow tank was full and so was the reservoir. After stopping for lunch, I removed the radiator cap to find that the coolant reservoir was full. We cruised at 75 mph and by the time we reached Chamberlain (140 miles), the overflow tank was completely full (not just to the maximum fill line, but to the top of the tank itself). My wife and I drove from Sioux Falls to Chamberlain, SD on Saturday to see the magnificent new sculpture, Destiny, that was recently placed along the bluff above the Missouri River. I have no issues with the coolant overflow tank when driving in town or during short trips on the interstate. I did a pressure test and could not find any coolant leaks. I replaced the plastic coolant reservoir with a Rocky Mountain Westy steel tank to eliminate the possibility that I had a faulty blue radiator cap. I replaced the fiberglass pipes with steel and replaced the rear heater core. I have found a few threads that address similar issues and have tried everything I can think of to fix the problem – except replacing the heads – without success.īased on suggestions from other threads, I replaced the radiator and all hoses. I fear that I have a head gasket issue, but the conversion engine had less than 20K miles on it when installed and I’ve driven less than 30K since installation. The van runs well but I have an ongoing problem with my coolant overflow tank filling up completely during highway trips. I bought the conversion as a turnkey kit from a highly respected company and installed the engine myself (following the provided directions that even a liberal arts major could understand). I have a 1988 Westy with a Subaru 2.5 engine conversion.
