    P1870 and a water damaged PCM….

    Hi again! Thanks for your replies! I am not sure if I would classify my environment as corrosive (live in an in-land climate with fairly nice summers and fairly cold winters, but I understand why you ask. I´ve only owned the vehicle for like 18 months and I have no history of what it has been...

    P1870 and a water damaged PCM….

    So, 1997 GMC Savana 1500. Problem no 1: Me and the family drove home from our camping vacation and after appr. 4 hours of driving, it started to slam in the second gear and lost the lockup. Since we were on the road and in the middle of nowhere (as you always are when things break down) we...

    1997 Savana, engine temp, fan clutch, trouble codes etc

    Hi again! Summer is over and I just wanted to report back. So, replaced the fan with an 11-blade and the engine temp. seemed to be more stable, never went past roughly 200 F. The new fan also made much less noise than the older so that was a nice upgrade. Also, no sign of any coolant loss during...

    1997 Savana, engine temp, fan clutch, trouble codes etc

    Thanks a lot for replying, I´m so glad to have found this forum! The thermostat has been replaced and it seems to be reaching normal operating temperature as it should. Intake gaskets were replaced last year along with an upgraded injection spider etc. When doing this, I remember now that...

    1997 Savana, engine temp, fan clutch, trouble codes etc

    Hello again! A little update: Oil pan is down. It was actually a quite easy job, I only had to remove the converter cover and loosen the bolts. It did slide right out just as L31MaxExpress said. However, when I took a little deeper look in it I noticed that there was a layer of milky sludge at...

    1997 Savana, engine temp, fan clutch, trouble codes etc

    So if I wanted to upgrade to the larger 5 quart pan, would I need to replace anything else beside the actual pan or is it just bolt on with no additional mods? Looking at Rockauto, there are 4 or 5 different brands...any thoughts on which one to choose, regardless of pan size? Thanks again!

    1997 Savana, engine temp, fan clutch, trouble codes etc

    Hi again! All right! Thank you so much for your replies! Regarding engine temp, I acutally looked at the ECT temp on the scanner to verify the gauge and it seems pretty accurate. About the fan blade, is GM 1580739 the way to go (as in bolt-on, no hassle) or is there another option as well...

    1997 Savana, engine temp, fan clutch, trouble codes etc

    Hello again! So, I´ve come across some new issues with the van (1997 Savana, Vortec 5.7) and I thought that maybe you guys could help me out. Again, I apologize if for any misspelling or incorrect choice of words as English isn´t my first language. Anyway, I would appreciate any help or...

    1997 GMC Savana 1500, intake gaskets, EGR plumbing etc

    First of all, I realize that this update is beyond late, there are probably bottle posts moving way faster than me in this case. I have no excuse except from a really bad memory combined with a busy day-to-day life, but hey, who doesn’t have that? All in all, I apologise for not responding back...

    1997 GMC Savana 1500, intake gaskets, EGR plumbing etc

    Hi again! First of all, thank you so much for all your replies and info, I really appreciate it. As an update/respons: I have ordered a remanufactured spider unit from Motor Man Fuel Injection which should be arriving within a week or so. I do not know whether this was a good choice or if...

    1997 GMC Savana 1500, intake gaskets, EGR plumbing etc

    Hi again! Just a little update. The intake is off and is now on the bench in the garage awaiting some further inspection. The hose connector seems to be fine and the leak I wrote about earlier seems to have been coming from the gaskets - leaking "upwards" towards the valve covers and on to the...

    1997 GMC Savana 1500, intake gaskets, EGR plumbing etc

    Hi again! Allright, I´ll just have to see what awaits when I eventually pull the intake manifold off. I think I´m better of tackling the hose connector then. Thanks again for all the advice and information. Tried searching for the ACDelco hose barb (15-33220 as shown in the linked thread) but...

    1997 GMC Savana 1500, intake gaskets, EGR plumbing etc

    Hi again! Thank you so much for all your swift replies, really appreciate it! I kind of suspected that you would need some sort of tune to "get rid" of the EGR. I suppose there are tuners in Sweden (somewhere...) who could tackle this operation but it seems, at least to me personally, like its...

    1997 GMC Savana 1500, intake gaskets, EGR plumbing etc

    Hi guys! New user and a lucky (?) owner of a Savana 1500 with a 350 Vortec. First of all, since English isn´t my mother tongue, I apologize for any misspellings and whatnot. Anyway, I´m currently working on the vehicle which my family and I are going to use as a "holiday-car" during this summer...
